【 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.
