Phys. Rev. E 52, 6818–6825 (1995)Simulation of an experiment on crystal extraction of 900-GeV protonsReceived 27 February 1995; published in the issue dated December 1995 A Fermilab experiment [R. A. Carrigan, Jr. et al. (unpublished)] on crystal extraction of 900-GeV protons from the Tevatron has been simulated with the Monte Carlo code catch [Biryukov, catch 1.4 User’s Guide, CERN SL Report No. 93-74, 1993 (unpublished); Phys. Rev. E 51, 3522 (1995)] tested earlier in the CERN-SPS crystal extraction experiment [Akbari et al., Phys. Lett. B 313, 491 (1993)]. Detailed predictions for the extraction efficiency, angular scans, and extracted beam profiles are presented. Furthermore, several ideas are proposed and tested by the simulation on how to get key information about the extraction experiment: the ‘‘septum width’’ of the crystal and the dependence of the extraction efficiency on it, the impact parameters of the incident protons, and the contribution of the first and multipasses to the extraction. With the use of simulation, we analyze ways to optimize the Fermilab experiment. (c) 1995 The American Physical Society © 1995 The American Physical Society URL:
