Abstract

The Fermilab crystal-extraction experiment E853 at Tevatron was simulated by Monte Carlo code CATCH [1] tested earlier in the CERN-SPS experiment [2-4]. Predictions for the extraction efficiency, angular scans and extracted beam profiles are presented. Several ideas are proposed and tested by the simulation, how to get in E853 the key information of the extraction experiment: the "septum width" of a crystal and dependence of extraction efficiency on it, the impact parameters of protons at crystal, and the contribution of the first and multi passes to the extraction. The ways to optimize E853 are analyzed.
