On possibility of crystal extraction and collimation at 0.1-1 GeV

Abstract

Bent crystal situated in a circulating beam can serve for efficient slow extraction or active collimation of the beams. This technique, well established at 10-1000 GeV, could be efficient also at the energies as low as 0.1-10 GeV according to the computer simulations presented in this paper. Applications might include halo scraping in the Spallation Neutron Source or slow extraction from synchrotrons.
