CASIM and ground water activation calculations at the A0 abort

摘要

The results of CASIM and ground water activation calculations for the A0 abort is presented in this paper. CASIM calculations were done at 150 GeV and 1 TeV for the following transverse beam sizes ({sigma}x{sigma}y): (0.15 x 0.15)mm{sup 2}, (0.15 x 0.15)cm{sup 2}, and (1.5 x 1.5)cm{sup 2}. The results from CASIM were used to calculate the ground water activation using the Concentration Model. The results show that there is only a weak dependence on the transverse beam size and that the maximum number of protons which can be aborted at A0 per year is 7.6 x 10{sup 16} protons/year {at} 150 GeV and 1.7 x 10{sup 16} protons/year {at} 1 TeV.
