“…Numerical simulations predict that relativistic protons interacting with a bent silicon crystal may be reflected with a deflection angle up to 1:5 C for R R C . Channeling in bent crystals is sometimes used in circular accelerators for beam steering [9], extraction, and collimation [10 -12], as well as for splitting and focusing [13] of external beams. Besides, there are on-going investigations to manufacture crystalline undulators [14] and to use bent crystals for measuring the magnetic moments of shortlived particles [15].…”

This paper presents a detailed study of the deflection phenomena of a 400 GeV=c proton beam impinging on a new generation of bent silicon crystals; the tests have been performed at the CERN Super Proton Synchrotron H8 beam line. Channeling and volume reflection angles are measured with an extremely precise goniometer and with high resolution silicon microstrip detectors. Volume reflection has been observed and measured for the first time at this energy, with a single-pass efficiency as large as 98%, in good agreement with the simulation results. This efficiency makes volume reflection a possible candidate for collimation with bent crystals at the CERN Large Hadron Collider.

A model for the simulation of orientational effects in straight and bent periodic atomic structures is presented. The continuum potential approximation has been adopted. The model allows the manipulation of particle trajectories by means of straight and bent crystals and the scaling of the cross sections of hadronic and electromagnetic processes for channeled particles. Based on such a model, an extension of the Geant4 toolkit has been developed. The code has been validated against data from channeling experiments carried out at CERN.
