Fission Mechanism of 235U+n Reaction According to the Symmetrical Atomic Nucleus Model

In this study, the variants of structures are considered for fission fragments of the 235U nucleus caused by thermal neutrons, depending on differences in the initial configuration of proton, neutron and alpha particle compositions, according to a symmetrical model developed for the atomic nucleus. The proposed model is based on the principles of spatial symmetry and the analysis of the binding energy of the nucleus, taking into account the quark structure of nucleons. For the first time, the number of alpha particles in the composition of the 235U nucleus is considered to be 44 and the total number of connections between nucleons is 292. The work compares the binding energy of fragments of the atomic nucleus 235U, which have the same number of protons and neutrons in their composition, but a different number of alpha particles. The results obtained are the basis for an experimental study on the energy characteristics of various fission options of the 235U+n reaction, which is of interest for improving the efficiency of nuclear power sources.

Absolute response of a proton detector composed of a microchannel plate assembly and a charge-coupled device to laser-accelerated multi-MeV protons.

The absolute response of a real-time proton detector, composed of a microchannel plate (MCP) assembly, an imaging lens, and a charge-coupled device (CCD) camera, is calibrated for the spectral characterization of laser-accelerated protons, using a Thomson parabola spectrometer (TPS). A slotted CR-39 plate was used as an absolute particle-counting detector in the TPS, simultaneously with the MCP-CCD detector to obtain a calibration factor (count/proton). In order to obtain the calibration factor as a function of proton energy for a wide range of proton numbers, the absolute response was investigated for different operation parameters of the MCP-CCD detector, such as MCP voltage, phosphor voltage, and CCD gain. A theoretical calculation for the net response of the MCP was in good agreement with the calibrated response of the MCP-CCD detector, and allows us to extend the response to higher proton energies. The response varies in two orders of magnitude, showing an exponential increase with the MCP voltage and almost linear increase with the phosphor voltage and the CCD gain. The calibrated detector enabled characterization of a proton energy spectrum in a wide dynamic range of proton numbers. Moreover, two MCP assemblies having different structures of MCP, phosphor screen, and optical output window have been calibrated, and the difference in the absolute response was highlighted. The highly-sensitive detector operated with maximum values of the parameters enables measuring a single proton particle and evaluating an absolute spectrum at high proton energies in a single laser shot. The absolute calibrations can be applied for the spectral measurement of protons using different operating voltages and gains for optimized response in a large range of proton energy and number.

Photon, charged particles, and neutron shielding properties of natural rubber/ SnO2 composites

The flexible shielding material based on natural rubber (NR) composites has been developed for radiation shielding materials. The natural rubber (NR) was prepared by incorporating Tin oxide (SnO2) with various loading levels. The addition content of SnO2 to natural rubber improved modulus at 100% elongation, hardness and specific gravity of natural rubber. while the tensile strength and elongation at break were reduced. The WinXCom program was used to calculate theoretical gamma ray shielding parameters. While, the Compton scattering technique was used to measure experimental values in the energy range of 0.223 MeV–0.662 MeV. The mass stopping power (MSP) and projected range (PR) have been simulated by SRIM coding for the proton and alpha particles. Moreover, the fast neutron shielding removal (FNSR) were calculated by Phy-X program. From the results, it was found that adding the SnO2 in the NR structure affected to increase of the photon, and charged particles, while the neutron shielding properties values decreased from adding the SnO2. These results reflect that the NR/SnO2 composites are suitable to apply as flexible radiation shielding materials.

Radiation shielding parameters and Micro-Raman spectral analysis of some pyroclastic rocks

In this study, the radiation shielding parameters of some pyroclastic rocks (Karabakir, Elazığ) were experimentally measured at 59.54–661.62 keV energy region. In addition, theoretical mass attenuation coefficients were calculated. Fast neutron removal cross section, exposure buildup factor, mass stopping power and projected range values for proton (H1) and alpha (He+2) particles were theoretically determined. The equivalent dose rates due to fast neutrons absorption by rock samples was measured experimentally using a241Am–Be fast neutron source with 10 mCi activity. Also, the elemental analysis of pyroclastic rocks was done by instrumental neutron activation analysis and inductively coupled plasma mass spectrometry. Minerals type and rock strength were evaluated by micro-Raman spectroscopy methods. The dose rate at detector is D0 when there is no sample between the neutron source and the detector, the dose rate at detector is Dd when there is a K-8 rock sample. The difference between the dose rates (Ds), was calculated and the equivalent dose rate absorbed by the K-8 rock sample was obtained as 0.2667 μSv⁄h. It is observed that K-8 rocks sample is a promising choice for gamma, neutron, proton and alpha shielding.

Experimental and theoretical investigation on physical, structure and protection features of TeO2–B2O3 glass doped with PbO in terms of gamma, neutron, proton and alpha particles

Glass series of composition 70TeO2- (30-x)B2O3- xPbO (where x = 2, 6, 10, 14 and 20 mol%) is prepared using melt-quenching technique. The glass structure was investigated by X-ray diffraction (XRD). Manufactured glass density, molar volume and Fourier transform infrared spectroscopy (FTIR) were measured. Shielding parameters against gamma-rays including, linear attenuation coefficient (μ), mass attenuation coefficients (μm), half-value layer (HVL) and mean free path (λ) were measured experimentally at energies of 0.664, 1.177 and 1.334 MeV using Cs137 and Co60 point sources and NaI(TL) scintillation detector. The measured parameters were compared with those calculated using XCOM program with a good agreement between them. To fully comprehend the shielding efficiency of the prepared glasses, several shielding parameters including, μm, HVL, effective atomic number (Zeff), electron density (Nel), equivalent atomic number (Zeq), exposure and energy absorption buildup factors (EBF & EABF), radiation protection efficiency (RPE) and kerma relative to air (Ka), were evaluated in the photon energy range 0.015–15 MeV and compared with some materials that commonly used as gamma-ray shielding. The findings demonstrate the viability of employing the current glass composition as an effective agent for gamma-ray shielding and fully protection (100%) for x-ray. The macroscopic effective removal cross section (ΣR) of the prepared glasses were calculated and compared with those of frequently used neutron shielding materials. Finally, the mass stopping power (MSP) and projected range (PR) values of proton (H1) and alpha particles (He+2) have been evaluated in the energy range 0.01–15 MeV. The results show that, increasing PbO content improves shielding characteristics. Among the examined samples, the S5 glass sample was found to be superior in terms of photon, neutron, proton and alpha particles protection. These results indicate that, the prepared glass samples are highly appropriate nuclear shielding material that can be used in many applications.

Characteristics and evolution of sheath and leading edge structures of interplanetary coronal mass ejections in the inner heliosphere based on Helios and Parker Solar Probe observations

Context. We investigated the plasma and magnetic field characteristics of the upstream regions of interplanetary coronal mass ejections (ICMEs) and their evolution as function of distance to the Sun in the inner heliosphere. Results are related both to the development of interplanetary shocks, sheath regions, and compressed solar wind plasma ahead of the magnetic ejecta (ME). Aims. From a sample of 45 ICMEs observed by Helios 1/2 and the Parker Solar Probe, we aim to identify four main density structures; namely shock, sheath, leading edge, and ME itself. We compared characteristic parameters (proton particle density, plasma-beta, temperature, magnetic field strength, proton bulk speed, and duration) to the upstream solar wind in order to investigate the interrelation between the different density structures. Methods. For the statistical investigation, we used plasma and magnetic field measurements from 40 well-observed Helios 1/2 events from 1974–1981. Helios data cover the distance range from 0.3–1 au. For comparison, we added a sample of five ICMEs observed with the Parker Solar Probe from 2019–2021 over the distance range of 0.32–0.75 au. Results. It is found that the sheath structure consists of compressed plasma as a consequence of the turbulent solar wind material following the shock and lies ahead of a region of compressed ambient solar wind. The region of compressed solar wind plasma is typically found directly in front of the magnetic driver and seems to match the bright leading edge commonly observed in remote sensing observations of CMEs. From the statistically derived density evolution over distance, we find the CME sheath becomes denser than the ambient solar wind at about 0.06 au. From 0.09–0.28 au, the sheath structure density starts to dominate over the density within the ME. The ME density seems to fall below the ambient solar wind density over 0.45–1.18 au. Besides the well-known expansion of the ME, the sheath size shows a weak positive correlation with distance, while the leading edge seems not to expand with distance from the Sun. We further find a moderate anti-correlation between sheath density and local solar wind plasma speed upstream of the ICME shock. An empirical relation is derived connecting the ambient solar wind speed with sheath and leading edge density. We provide constraints to these results in this paper. Conclusions. The average starting distance for actual sheath formation could be as close as 0.06 au. The early strong ME expansion quickly ceases with distance from the Sun and might lead to a dominance in the sheath density between 0.09 and 0.28 au. The leading edge can be understood as a separate structure of compressed ambient solar wind directly ahead of the ME and is likely the bright leading edge of CMEs often seen in coronagraph images. The results allow for better interpretation of ICME evolution and possibly the observed mass increase due to enlargement of the sheath material. The empirical relation between sheath and leading edge density and ambient solar wind speed can be used for more detailed modeling of ICME evolution in the inner heliosphere.

Mass stopping power and nuclear shielding behavior of lead borate glasses: Influence of gamma irradiation on physical properties

Four glassy systems with dissimilar PbO ratios were synthesized by the melting method. Raman scattering was used to study the chemical bonds inside the glass structures and follow the chemical changes occurring inside their networks after using the glasses in a radiation field. The glass samples are based on several tetrahedral and triangular groups where in BO3 is predominant. The energy gap of each sample was calculated from two different equations extracted from absorption and transmission measurements as ETauc and ETrans, respectively. Also, chemical durability has been studied to show the stability of these glasses against acidic environmental effect and followed by SEM images. Our findings showed that radiation effect on the prepared samples did not cause significant variations of structural and optical characteristics, however, increasing PbO concentrations resulting in enhancement of several radiation attenuation competencies. This study presented a comprehensive study of the radiation shielding properties of lead borate glass by assessing the effectiveness of proton, electron, neutron, and gamma shielding. Mass stopping power (ψp) and projected range (PR) values were calculated for proton particles (H1) using SRIM Monte Carlo simulation code and its subroutine TRIM, which predicts the radiation damage and atomic displacements per atom (dpa), while the ESTAR program was used to calculate ψe and the continuous slowing down approximation (CSDA) range for electrons. Furthermore; the findings estimate the excess lifetime cancer risk% for radiation workers behind the glass shields. Also, the glass with the lowest PbO content has the highest ΣR value, whereas the sample with the highest PbO content has the highest MAC value of gamma rays.

Charged Particles and Gamma-Ray Interaction with Gallium Barium Borate Glass: Theoretical Approach

The charged particle and gamma-ray shielding properties of gallium barium borate glass in composition (80-x)B2O3: xBaO: 20Ga2O3 (where x = 5, 10, 15, 20 and 25 mol%) were calculated and discuss in this work. The mass attenuation coefficient (μm), the effective atomic number (Zeff) and the effective electron density (Neff) were calculated by using the WinXCom program in the energy range from 1 keV to 2 MeV. The results show the mass attenuation coefficients (μm), the effective atomic number (Zeff) , and the effective electron density (Neff) increase with increasing of BaO content reflected higher interaction probability at higher BaO composition in the glass matrix. The result of build-up factor are in the same trend and show the high value in the region which incoherent scattering is the main interaction. The mass stopping power and the projected range of proton and alpha particle have been simulate by SRIM program. The mass stopping power has maximum value at 0.9 MeV and 0.07 MeV for proton and alpha particles respectively. The projected range have the higher value at the higher kinetic energy of proton and alpha particle. Moreover the gallium barium borate glass system better have the proton and alpha shielding preperty when add barium oxide concentration due to weight fraction of barium increase in glass matrix.

Charge transfer of potassium by the impact of proton particle

The total cross section for electron capture is being calculated in this paper for 2s state of hydrogen atom in proton-potassium collision. The energy range chosen for the calculation is 50 keV to 10,000 keV and we have used Coulomb projected Born (CPB) approximation method. Also the differential cross section at different scattering angle has been calculated. The result obtained are compared with available theoretical data and found it to be in good agreement.

Investigating charm production and fragmentation via azimuthal correlations of prompt D mesons with charged particles in pp collisions at mathbf {sqrt{ s} = 13} TeV

Angular correlations of heavy-flavour and charged particles in high-energy proton–proton collisions are sensitive to the production mechanisms of heavy quarks and to their fragmentation as well as hadronisation processes. The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in proton–proton collisions at a centre-of-mass energy of sqrt{s} = 13 TeV with the ALICE detector is reported, considering mathrm D^{0} , mathrm D^{+} , and mathrm D^{*+} mesons in the transverse-momentum interval 3< p_{mathrm{T}} < 36 GeV/c at midrapidity (|y| < 0.5), and charged particles with p_{mathrm{T}} > 0.3 GeV/c and pseudorapidity |eta | < 0.8. This measurement has an improved precision and provides an extended transverse-momentum coverage compared to previous ALICE measurements at lower energies. The study is also performed as a function of the charged-particle multiplicity, showing no modifications of the correlation function with multiplicity within uncertainties. The properties and the transverse-momentum evolution of the near- and away-side correlation peaks are studied and compared with predictions from various Monte Carlo event generators. Among those considered, PYTHIA8 and POWHEG+PYTHIA8 provide the best description of the measured observables. The obtained results can provide guidance on tuning the generators.

Proton, Alpha, and Gamma Rays Interactions of CsI(Na) Scintillator Using the Theoretically Computational Program

The charged particles and photon interaction parameters of CsI(Na) scintillator were calculated by the theoretically computational program. The Phy-X programs were used to calculation gamma rays interaction at an energy range of 1 keV to 100 GeV. The stopping and range of ions in matter program were used for measurement the proton and alpha particles. The result found that the total mass attenuation coefficient decreased with the increasing of the high photon energy range and found the discontinuous energy due to the absorption edge of Cs and I. The effective atomic number and the effective electron density found the same trend with the total mass attenuation coefficient. The data of mass stopping powers for proton and alpha particle increase to the maximum value at kinetic energy 0.09, 0.6 MeV, respectively. The results showed that the energy at 5 keV, the ions entering the scintillator penetrate less deeply than the energy of the ions at 10 keV.

Gamma, neutron, and heavy charged ion shielding properties of Er3+-doped and Sm3+-doped zinc borate glasses

AbstractThis study aimed to investigate the nuclear radiation shielding properties of erbium (Er)-reinforced and samarium (Sm)-reinforced borate glasses. In the 0.015–15 MeV photon energy range, attenuation coefficients, as well as half-value layer tenth-value layers, and the mean-free path have been calculated. Additionally, effective, and equivalent atomic numbers, effective atomic weight, electron density, and exposure and energy absorption build-up factors were also calculated. To evaluate the overall nuclear radiation attenuation competencies of Er-rich and Sm-rich glasses, effective removal cross-section values for fast neutrons and projected range/mass stopping power values for alpha and proton particles were also determined. The glass sample BZBEr2.0 had the highest linear and mass attenuation coefficients (µandµm), effective conductivity (Ceff), the effective number of electrons (Neff), and effective atomic number (Zeff) values as well as the lowest half-value layer (T1/2), tenth value layers (T1/10), mean free path (λ), exposure build-up factor, and energy absorption build-up factor values.µmvalues were reported as 2.337, 2.556, 2.770, 2.976, 2.108, 2.266, 2.421, 2.569, and 2.714 for BZBEr0.5, BZBEr1.0, BZBEr1.5, BZBEr2.0, BZBSm0.0, BZBSm0.5, BZBSm1.0, BZBSm1.5, and BZBSm2.0 glass samples at 0.06 MeV, respectively. The results showed that Er has a greater effect than Sm regarding the gamma-ray shielding properties of borate glasses. The results of this investigation could be used in further investigations and added to older investigations with the same aim, to aid the scientific community in determining the most appropriate rare-earth additive, to provide adequate shielding properties based on the requirement.

Developments in Mathematical Algorithms and Computational Tools for Proton CT and Particle Therapy Treatment Planning

We summarize recent results and ongoing activities in mathematical algorithms and computer science methods related to proton computed tomography (pCT) and intensity-modulated particle therapy (IMPT) treatment planning. Proton therapy necessitates a high level of delivery accuracy to exploit the selective targeting imparted by the Bragg peak. For this purpose, pCT utilizes the proton beam itself to create images. The technique works by sending a low-intensity beam of protons through the patient and measuring the position, direction, and energy loss of each exiting proton. The pCT technique allows reconstruction of the volumetric distribution of the relative stopping power (RSP) of the patient tissues for use in treatment planning and pretreatment range verification. We have investigated new ways to make the reconstruction both efficient and accurate. Better accuracy of RSP also enables more robust inverse approaches to IMPT. For IMPT, we developed a framework for performing intensity modulation of the proton pencil beams. We expect that these developments will lead to additional project work in the years to come, which requires a regular exchange between experts in the fields of mathematics, computer science, and medical physics. We have initiated such an exchange by organizing annual workshops on the pCT and IMPT algorithm and technology developments. This report is, admittedly, tilted toward our interdisciplinary work and methods. We offer a comprehensive overview of results, problems, and challenges in pCT and IMPT with the aim of making other scientists wanting to tackle such issues and to strengthen their interdisciplinary collaboration by bringing together cutting-edge know-how from medicine, computer science, physics, and mathematics to bear on medical physics problems at hand.

Accelerators, Gantries, Magnets and Imaging Systems for Particle Beam Therapy: Recent Status and Prospects for Improvement.

The paper begins by emphasizing the clinical and commercial importance of proton or other charged particle such as carbon ion therapy, refers to the manufacturers of such systems of which more than 120 are installed or under construction worldwide by April 2021. A general review of charged particle therapy systems refers to six manufacturers and provides in tabular form some details of systems installed in the US, Europe, Asia, and elsewhere. In a description of the principles of particle beam therapy a comparison is made of the properties of photons (x-rays) versus protons and protons versus carbon ions. A brief discussion of accelerators in general is followed by descriptions of cyclotrons (including the isosynchronous cyclotron and the synchrocyclotron) and synchrotrons. An interesting case study describes the evolution of a normal-conducting 220 ton cyclotron into an iron-free synchrocyclotron weighing only 5 tons. The general principles of beam handling and gantry design are described. Subsequent sections describe gantry magnets in detail - normal conducting gantry magnets, superconducting gantry magnets for proton- and carbon therapy. Mention is made of a novel CERN-designed superconducting toroidal gantry for hadron therapy, GaToroid. This device, operating under steady state current and magnetic field, is able to deliver a beam at discrete angles over a range of treatment energies. Also considered are low temperature superconducting (LTS) and high temperature superconducting (HTS) magnet windings, and the choice of REBCO conductors for cryogen-free carbon-ion gantries. Finally, the paper mentions an important “Prospect for Improvement”, viz: the introduction of MRI image guidance. A well-known property of the particle beam as it passes through tissue is its energy dependent absorption that rises to a pronounced peak (the Bragg peak) at the end of its range. In order to take advantage of this effect the exact targeting of the tumor and positioning of the patient should be guided by imaging visualization using X-ray, CT, and hopefully advanced MRI. Unlike MRI-guided photon therapy the direct interaction of the magnetic field with the charged particle beam presents a huge challenge such that MRI image-guided proton/particle therapy has not yet been available in clinical practice. Modeling studies have been undertaken on the general topic of beam-line/magnetic field interaction using, for example, the software GEANT4 (GEometry And Tracking) a platform for simulating the passage of charged particles through matter using a Monte Carlo method.

Description for N = 126 Isotones 210Po and 212Rn with Particle-Hole Excited Nucleon-Pair Approximation and Realistic Effective Interaction

In this paper, we study yrast states of two N=126 isotones 210Po and 212Rn using the nucleon-pair approximation with particle–hole excitations and using a low-momentum interaction Vlow–k renormalized from the free CD-Bonn NN potential. An overall good agreement with experimental level structures, B(E2)s, and B(E3)s, is achieved. We also calculate the probabilities of neutron particle–hole excitations in these yrast states, with a focus on negative-parity states, which reflect the roles played by the neutron negative-parity configurations of one-particle-one-hole excitations across the N=126 shell gap and the negative-parity configurations of valence proton particles involving the 0i13/2 orbit. The N=126 shell gap is discussed in terms of energies of neutron one-particle-one-hole excitations.

Effect of low energy proton and He particle irradiation on CsPbBr3 material

In this paper, the effect of proton and He particle bombardment in CsPbBr3 material was investigated by the Monte Carlo simulation including ion range, backscattering, vacancies and sputtering yield. The energies of proton and He particle varied from 50 keV to 180 keV and the particle incidence angles increased from 0o to 89.9o . The calculated results showed that with the increase of incidence energies, the range and vacancies increased, and the backscattering ions and sputtering yield reduced for proton and He particle. Meanwhile, the vacancies, backscattering ions and sputtering yield induced by He particle were much more proton at the same energy. With the increase of incidence angles, the range and vacancies were reduced, and the sputtering yield increased for proton and He particle. Also, it is obvious that the effects of He particle on CsPbBr3 material were much more serious than proton.

Measuring the 15O(α, γ)19Ne reaction in Type I X-ray bursts using the GADGET II TPC: Hardware

Sensitivity studies have shown that the 15O(α, γ)19Ne reaction is the most important reaction rate uncertainty affecting the shape of light curves from Type I X-ray bursts. This reaction is dominated by the 4.03 MeV resonance in 19Ne. Previous measurements by our group have shown that this state is populated in the decay sequence of 20Mg. A single 20Mg(βp α)15O event through the key 15O(α, γ)19Ne resonance yields a characteristic signature: the emission of a proton and alpha particle. To achieve the granularity necessary for the identification of this signature, we have upgraded the Proton Detector of the Gaseous Detector with Germanium Tagging (GADGET) into a time projection chamber to form the GADGET II detection system. GADGET II has been fully constructed, and is entering the testing phase.

Computational approach of alpha and proton interaction of gadolinium bismuth borate glass system using SRIM program

The purpose of this research is used to study the alpha and proton shielding characteristics of gadolinium bismuth borate glass with chemical compositions (80-x)B2O3: 5CaF2: 15Bi2O3: xGd2O3 (where × = 0, 5, 10, 15, and 20 mol%). The mass stopping power (MSP) and projected range (PR) have been calculated by SRIM program for the proton and alpha particles. From the calculation, it was found that the proton mass stopping power (PMSP) value and alpha mass stopping power (AMSP) values tended to decrease with increasing Gd2O3 concentration. From the analysis, adding the Gd2O3 content in the glass affects the structure which increase the alpha and proton shielding properties. Likewise, the values of proton projected range (PPR) and alpha projected range (APR) were found to decrease with increasing Gd2O3 content. From the analysis, adding the Gd2O3 content to the glass affect the increase in the alpha and proton shielding properties. These results suggest that gadolinium bismuth borate glass is suitable to develop as alpha and proton shielding materials.

Optical, structural, physical, and nuclear shielding properties, and albedo parameters of TeO2–BaO–B2O3–PbO–V2O5 glasses

In this study, glass systems were constructed according to the formula 34TeO2∙xBaO∙35B2O3∙(30-x)PbO∙1V2O5 (x=0, 5, 10, 15, 20, 30 mol%). The gamma, neutron, proton, and alpha shielding characteristics of the glasses were evaluated for nuclear security applications. The mass attenuation coefficient (MAC), half-value layer, mean free path, effective atomic number, and radiation protection efficiency (RPE) were experimentally measured in the energy range of 59.54–661.62 keV. In addition, the theoretical MAC values were determined. The exposure buildup factor, fast neutron removal cross section, mass stopping power, and projected range values for proton (H1) and alpha (He+2) particles were theoretically determined. Albedo parameters were measured for the prepared glasses at photon energy of 59.54 keV. The optical and structural properties were studied using X-ray diffraction, FT-IR Fourier transform infrared, ultraviolet–visible, and electron paramagnetic resonance spectroscopy. The glass samples comprised structural units such as TeO4, TeO3, BO3, and BO4. The spin Hamiltonian parameters, g∥, g⊥, A∥, A⊥, dipolar hyperfine coupling parameter, P, and Fermi contact parameter, κ, were calculated. The molecular orbital parameters, α2, β2, and γ2, were determined by optical absorption spectroscopy. The number of bonds per unit volume in the glasses ranged between 8.763 and 9.212×1028 m−3. The most reflective compound among the glasses investigated was BaO. Good agreement was found between the theoretical and experimental MAC values. TeBaBPbV1 glass was identified as a potential candidate for use in neutron, gamma, proton, and alpha shielding.
