Preliminary Calculation Results for the Sr-82 Production

The 82Sr had been produced by the irradiation of molybdenum with 800 MeV protons at Los Alamos Meson Physics Facility [2-3]. From 1980's the RbCl target has been used for 82Sr production instead of Mo. A 100-MeV proton linear accelerator has been constructed at the end of 2012 and the target irradiation facility for RI production was established in 2016 at the KOMAC (Korea Multi-purpose Accelerator Complex) in Gyeongju. Radio-nuclides which can be produced by high-energy proton beam irradiation, such as 67Cu, 82Sr, etc. are main nuclides interested in by KOMAC. In this paper, some calculation results for 82Sr using 100-MeV proton accelerator are presented. As a result, we can found out that we can optimized the irradiation conditions by using SRIM code and MCNPX code. After optimization of the irradiation condition on the basis of the 82Sr production yields calculated by MCNPX code simulation, the proton beam energy reached to the target can be calculated by SRIM code simulation.
