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

TL;DR

This paper explores the potential of using bent crystals for beam extraction and collimation at low energies (0.1-1 GeV), supported by computer simulations, expanding their application beyond high-energy regimes.

Contribution

It demonstrates through simulations that bent crystal techniques can be effective for beam manipulation at energies as low as 0.1-10 GeV, previously established mainly at higher energies.

Findings

Simulations indicate feasibility of crystal extraction at low energies.

Potential applications include halo scraping and slow extraction in existing facilities.

Efficiency comparable to high-energy applications suggested.

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.
