Interaction of High-Energy Proton Beam With a Thin Target and Multiplicities of Neutron
(2007) Demirkol, I.; Arasoǧlu, A.; Tel, E.; Tatar, M.; Şafak, M.S.
An important ingredient in the performance of accelerator driven systems for energy production, waste transmutation and other applications are the number of spallation neutrons produced per incident proton. The neutron multiplicities, angular and energy distributions are usually calculated using simulation codes. We have presented multiplicities of the neutrons emitted in the interaction of a high-energy proton (1500 MeV) with a thin target Pb, Bi. In this study we have used the code ISABEL to calculate multiplicities of the neutron emitted. The results obtained have been compared with the available data. © 2007 American Institute of Physics.
Triton Emission Spectra in Some Target Nuclei Irradiated by Ultra-Fast Neutrons
(Springer, 2010) Tel, E.; Kaplan, A.; Aydin, A.; Buyukuslu, H.; Demirkol, I.; Arasoglu, A.
High-current proton accelerator technologies make use of spallation neutrons produced in (p,xn) and (n,xn) nuclear reactions on high-Z targets. The produced neutrons are moderated by heavy water. These moderated neutrons are subsequently captured on (3)He to produce tritium via the (n,p) reaction. Tritium self-sufficiency must be maintained for a commercial power plant. So, working out the systematics of (n,t) reaction cross sections and triton emission differential data are important for the given reaction taking place on various nuclei at different energies. In this study, triton emission spectra by using ultra-fast neutrons (incident neutron energy > 50 MeV), the (n,xt) reactions for some target nuclei as (16)O, (27)Al, (56)Fe, (59)Co, (208)Pb and (209)Bi have been investigated. In the calculations, the pre-equilibrium and equilibrium effects have been used. The calculated results have been compared with the experimental data taken from the literature.
