Monitoring of tritium in surface waters in PC, Nuclear facilities of Serbia

The isotope of hydrogen, tritium, is a radioactive isotope, in most cases it is found bonded to molecules that replace hydrogen. It can be found in nature as a product interactions of cosmic radiation with air or atmospheric molecules nitrogen, such tritium is natural. There is also anthropogenic tritium that contributes increased levels of natural tritium. Artificially produced tritium is produced in testing of nuclear weapons, in the operation of nuclear power plants and processing nuclear fuel. This paper will describe the methods of tritium detection liquid scintillation detector Quantulus 1220 by direct method in duration of 300 minutes at the Department of Nuclear Physics. Surface water samples with tritium was taken from the location of PC Nuclear facilities of Serbia from the Mlaka stream. The monitoring recorded an increase in tritium content at two locations, which indicates failures of nuclear waste storage.

Accelerator mass spectrometry with ANU’s 14 million volt accelerator

Accelerator Mass Spectrometry (AMS) at the Department of Nuclear Physics and Accelerator Applications (Australian National University) is based on a 14UD tandem accelerator. The 14UD has demonstrated exceptional accelerator performance over more than three decades of AMS, e.g. by running regularly above 14 MV. We present the actual performance for the whole range of measured radionuclides and the potential of this specialised high-energy AMS facility - demonstrating the continuing need for such a system. Focus here will be also on the unique setup comprising an Enge split-pole spectrograph used as a gas-filled magnet (GFM). The GFM has seen growing importance at ANU over the years as a means for providing an efficient reduction of isobaric background. We use the Enge now routinely for 10Be, 26Al, 32Si, 53Mn and 60Fe measurements.

Outreach and engagement in Australia and the Indo-Pacific region

Outreach and engagement activities have been core functions of the Australian National University Department of Nuclear Physics for many years. Staff and students of the Department play an important role in educating local high school students, Australian Federal Government employees and the general public. As the ‘national’ university, we also accept a social responsibility to undertake endeavours that align with Australia’s broader strategic priorities. One of these is to make a positive, sustained contribution to the overall growth and development of our geographical neighbours. Here, I report on the existing program of local outreach at the ANU Heavy Ion Accelerator Facility, selected international engagement activities and comment on opportunities for future growth.

Status and activities of the LAFN (Laboratório Aberto de Física Nuclear)

A brief panorama is given about the status and the research activities of the LAFN - Laboratório Aberto de Física Nuclear (the “Open Nuclear Physics Laboratory”). The LAFN is an internal organization of the Nuclear Physics Department of the Institute of Physics of the University of São Paulo, São Paulo, SP, Brazil, which was created in the late 90’s in order to facilitate the participation of users from other institutions in Brazil or abroad. Presently the Laboratory has more than 70 registered users, most of them active in proposing and performing experiments with the 8MV Pelletron-Tandem particle accelerator, which is a mayor nuclear physics research facility in Brazil. The experiment proposals are evaluated by a project advisory committee. It is characteristically a University based facility, with abundant participation of students, and production of several MSc and PhD theses regularly. The organizational structure of the Laboratory, and the characteristics of the Accelerator and peripherals will be described, as well as selected topics of the ongoing research both on basic and applied nuclear physics, such as nuclear structure and reaction mechanism studies with stable and radioactive beams, and tests of irradiation damage and other effects on electronic devices. Presently, the LAFN is part of the INCT-FNA (“Instituto Nacional de Ciência e Tecnologia - Física Nuclear e Aplicações”), supported by several Federal and State institutions from Brazil.

Physics architecture. Part two

Physics architecture. Part two. The talk is devoted to the jubilee of academician M.A. Markov, who was born in 1908. Now we have also the 100th anniversary of the gauge invariance principle proposed by Weyl in 1918. During the period from 1967 to 1988 M.A. Markov was Academician Secretary of Nuclear Physics Department of AN USSR. He organized the series of conferences dedicated to the topical problems of theoretical, nuclear and elementary particle physics. One of them was international seminar “Vector mesons and electromagnetic interactions” under A.M. Baldin direct leadership. It went off in JINR in September of 1969. This very that seminar gave birth to the conferences series named “Baldin autumn”. Thanks to the discussions at the A.M. Baldin seminar many critical situations in theoretical and experimental physics were subsequently settled. The first plenary session of the seminar included L.D. Faddeev talk about gauge field quantization, which cleared the way to develop the renormalized quantum gauge field theory. My talk was dedicated to the transformation of the classical gauge field theory into geometrical one. As a result the unified geometrical theory was obtained, which could include any interactions together with Einsteinian gravity. In this connection both formulations of Weyl’s local gauge invariance principle (of 1918 and 1929) as well as Einsteinian principle of general relativity were used. This approach was based on the fibre bundle geometry, which was developed by mathematicians at that time. This theory gives a realizable classification of interactions according to the local Lie’s symmetry groups associated with them. This approach leads to the VIth Hilbert’s problem solution. To obtain further development of the gauge field theory, it is necessary to decide the question of the gauge field mass origin. It is the key moment both in quantum and geometrical classical theories of the gauge fields. Therefore it is very important to analyze the experiments, where massive and massless particles are converted in each other (similar Baldin experiments in JINR in 1967).

A Low Background Gamma Ray Spectrometer with Anticosmic Shielding

The article describes a gamma ray spectrometer protected by a lead shield (Model 747E Canberra lead shield) and an active shield made of an 80~cm \(\times\) 80~cm \(\times\) 3~cm plastic scintillator plate in anticoincidence on top of the lead shield. The detector used as low background gamma-spectrometer is a high purity Germanium crystal of model GC2018 Canberra. The background count rate currently achieved (30-2400 keV) is 1.27 cps without anticoincidence. The level of background suppression obtained from the active protection is 0.80 overall and about 0.43 for the 511 keV gamma line. The gamma ray spectrometer is installed and operated in the Nuclear Laboratory, Department of Nuclear Physics, University of Science, HCMC-Vietnam National University.

Mesenteric blood flow during vasovagal syncope

s selected for presentation 3.6 Mesenteric blood flow during vasovagal syncope D. Jardine, R. Pointon, I. Wright, T. Buckenham Department of General Medicine, Christchurch Hospital, New Zealand Department of Nuclear Physics, Christchurch Hospital, New Zealand Department of Radiology, Christchurch Hospital, New Zealand Rapid vasoconstriction of the splanchnic arterioles, controlled by the sympathetic nervous system is thought to be the most important mechanism for maintaining blood pressure during posture change, exercise and haemorrhage. It has been hypothesised that during vasovagal reactions, the baroreflexes transiently fail, allowing blood to pool in the splanchnic vessels. This results in decreased venous return and a steady fall in stroke volume output during the minutes preceding syncope.We aimed tomeasure mesenteric artery blood flow during tiltinduced syncope to see if “active” vasoconstriction was maintained as blood pressure fell.We selected 40 patients with a history of fainting and during 70-degree head-up tilt, we continuously monitored blood pressure [MAP] [Finapress], heart rate [HR] and muscle sympathetic nerve activity [MSNA]. We also did pulsed-doppler measurements from the superior mesenteric artery each minute. Using the pixel-averaging techniquewe quantified the area under thewave signal representative of diastolic flow and normalised this for systolic flow [NDF]. Patients were tilted for 30 minutes [GTN given at 20 minutes] or until presyncope. 18 patients [age 41 ± 15 yrs, 9 females] had tilt-induced presyncope after 21 ± 8minutes. During the last 5 minutes of tilt: BP fell from 98± 12mmHg to 70 ± 18 [p= 0.001]; HR from 82± 12 bpm to 74± 18 [p= 0.09]; MSNA from 47 ± 9 bursts/min to 37 ± 13 [p= 0.04] and NDF from 0.92 units to 0.75 [p= 0.02]. Despite a fall in MSNA during presyncope, active vasoconstriction is maintained in the splanchnic arterioles resulting in decreased diastolic blood flow. Stroke volume falls at this time, therefore a relative increase in systolic flow is not contributing to the fall in NDF. The dominant hypotensive mechanism in vasovagal syncope is likely to be splanchnic venous pooling which occurs despite decreased arterial inflow. doi:10.1016/j.autneu.2015.07.264 Symposium 4: Is renal nerve ablation a sound therapeutic strategy for the clinical treatment of hypertension?

Discrimination of cosmic-ray in scintillation region and light-guide for plastic scintillation detectors using 5GSPS readout system

At sea level, the measurement of energy spectrum for cosmic-ray flux determination using two-coincidence plastic scintillation detectors with “traditional” electronic-readout system may include not only cosmic-ray in scintillator region but also light-guide region. In this work, we carry out a measurement of cosmic-ray using two-coincidence plastic scintillation detectors with size of each 80cm×40cm×3cm thick, and an electronic-readout system of 5GSPS (i.e. 200 ps sampling-time resolution). With the readout system, the shapes of pulses from scintillation detectors can be observed. The behavior of time responses of pulses in a plastic scintillator and a light-guide may be different. Based on some characteristics of these responses (such as pulse width, its falling edge, etc. ), it is possible to discriminate cosmic-ray in scintillation region from light-guide region. The vertical cosmic-ray flux was measured to 0.1×10-3count.s-1cm-2. The obtained results will be presented and discussed in detail. The experiment was set up and measured at the Nuclear laboratory, Department of Nuclear Physics, University of Science, HCMC-Vietnam National University

Correction of matrix effects in XRF with the samples of two elements of Fe-Cr

A study on the correction of matrix effects in XRF with samples of two elements of Fe-Cr was carried out. The measurement of XRF was excited by H3-Zr source at the Nuclear Physics Department, University of Science HCM City. In this study, Claisse-Quintin algorithm was applied to adjust the absorption effects in analysis of Fe-Cr concentration in the samples. As the results, obtained concentrations were, wFe = 0,39 ± 0,02 (g/g) and wCr = 0,40 ± 0,01 (g/g). Here, there is a very good with agreement in concentration between standard and sample, which deviation from 0.01 % to 2 %.

Development of environmental radiation monitoring system using inspector+ and FPGA board

In this report, we present the development of an environmental radiation monitoring system. The system includes Inspector+ dose meter, FPGA board, and LabVIEW interface. In the electronic board using FPGA, the embedded VHDL program is developed for FPGA board. Its functions are to accumulate pulse signals from the Inspector+, transmit data to the computer. Computer interface is written on LabVIEW platform. Its functions are to receive data from FPGA board, plot data, store data, as well as control the FPGA board. We evaluate the response of the system by using a standard pulse generator. With this system, we carry out the measurement of environmental background radiation in two experimental rooms and outside at Nuclear physics Department, University of Science, VNU-HCMC.

George Dionisios Dracoulis

Nuclear physicist George Dionisios Dracoulis had a vibrant and charismatic personality. As a meticulous researcher, he was known for the reliability of his results—if George had measured it, then you knew it was right. And he took his wit and wisdom outside the laboratory when he served as a respected science adviser to the Australian government. He passed away at home in Canberra, Australia, on 19 June 2014 after a short battle with cancer.George Dionisios DracoulisPPT|High resolutionBorn in Melbourne, Australia, on 19 December 1944, George pursued his undergraduate and postgraduate studies at the University of Melbourne, from which he received a PhD in nuclear physics in 1970. After a three-year postdoctoral research position at the University of Manchester in the UK, he returned to Australia to take a research position at the Australian National University in Canberra, where the world’s largest tandem Van de Graaff heavy-ion accelerator was under construction. George played an integral, and soon leading, role in the accelerator’s development and exploitation as a research facility. As head of the university’s department of nuclear physics from 1992 until his retirement in 2009, he established it as one of the most respected nuclear-physics laboratories in the world.In retirement, George continued as an indefatigable researcher. He traveled the world to perform experiments and speak at conferences until diagnosed with kidney cancer in March of this year. In addition to having a network of friends and colleagues around the globe, George enjoyed extended visits to Stony Brook University in New York, Argonne National Laboratory in Illinois, Lawrence Berkeley National Laboratory in California, and the University of Surrey in the UK.George made seminal contributions to the understanding of nuclear structure: the way different nuclear shapes can coexist; the way nuclear vibrations, especially octupole vibrations, can couple to neutron and proton excitations; and the way metastable excited states, or isomers, can be used to probe nuclear spin and shape properties. He was renowned for the thoroughness of his experimental approach, which he combined with a deep physical understanding of nuclear phenomena.Among the numerous awards George received were the Australian Academy of Science’s 2003 Thomas Ranken Lyle Medal for outstanding contributions to our understanding of the structure of atomic nuclei and the Australian Institute of Physics’ 2004 Walter Boas Medal for excellence in physics research.George served as a member of the Australian Prime Minister’s Select Task Force on Uranium Mining, Processing and Nuclear Energy in 2006. As professor emeritus, he remained active in public education and continued to engage with the media and in the public discussion of nuclear energy and nuclear technology. George also continued his nuclear-physics research work until only a few weeks before he died.George will be greatly missed by his family, friends, and colleagues around the world.© 2014 American Institute of Physics.
