Abstract
HiSPANoS (HiSPAlis Neutron Source) is the first accelerator-based neutron facility in Spain, installed at the Centro Nacional de Aceleradores (CNA), where different experiments have been performed related to nuclear astrophysics, detector characterization, electronic devices irradiation, imaging, etc. An upgrade of the neutron facility has been carried out recently, installing a pulsing system at the 3 MV tandem accelerator at CNA. Such system, composed by a chopper and buncher unit, can provide nanosecond proton and deuteron pulsed beams. A new experimental line dedicated to neutron time-of-flight (n-TOF) technique has been installed at the tandem accelerator. Proton and deuterium pulse width of 1 ns have been measured with a repetition rate in the range of 62.5 kHz to 2 MHz. The commissioning of the n-TOF line has consisted of the measurement of the neutron field generated by 7Li(p,n) reaction with proton energy of 1912 keV.
Highlights
HiSPAlis Neutron Source (HiSPANoS) is the first accelerator-based neutron source (ABNS) installed in Spain
For several years, HiSPANoS is operating as the first accelerator based neutron source in Spain
In order to improve its possibilities by means of neutron time-of -flight technique, an upgrade has been realized
Summary
HiSPAlis Neutron Source (HiSPANoS) is the first accelerator-based neutron source (ABNS) installed in Spain. The main purpose is to develop experimental measurements applying the neutron time-of-flight (TOF) technique. If neutrons are produced with a pulsed ion beam, time information is added, so neutron velocities may be measured.
