Mono-energetic neutron fields using 4 MV pelletron accelerator at FRS/JAEA

Tanimura, Yoshihiko; Kowatari, Munehiko; Yoshitomi, Hiroshi; Nishino, Sho; Yoshizawa, Michio

Mono-energetic neutron calibration fields have been developed in the energy range of 8 keV to 19 MeV using a 4 MV Pelletron accelerator at the FRS in the JAEA. Protons or deuterons are accelerated and transported to bombard various targets for neutron production. The targets are prepared by depositing Sc, LiF or TiT on the backing disks for $$^{45}$$Sc(p,n)$$^{45}$$Ti, $$^{7}$$Li(p,n)$$^{7}$$Be and, $$^{3}$$H(p,n)$$^{3}$$He and $$^{3}$$H(d,n)$$^{4}$$He reactions, respectively. For $$^{2}$$H(d,n)$$^{3}$$He reaction, a gas target is prepared by filling a target cell with D$$_{2}$$ gas. A pulsed beam with a minimum width of 2 ns can be derived with the pulsing system. Neutron fluence rates were measured with a Bonner sphere, a Li glass detector, a Si-SSD with a polyethylene radiator and a BC501A detector. Though the maximum fluence rates should not be high enough to obtain the nuclear data using an activation method, they can be available to obtain the nuclear data by using the prompt $$gamma$$ ray analysis.
