Description

Beam steering performance of bent silicon crystals irradiated with high-intensity and high-energy protons have been studied. In particular, crystals of the type used for collimation purposes at the CERN Large Hadron Collider have been irradiated at the HiRadMat CERN facility with 2.5 x 10^13 440 GeV protons, with a pulse length of 7.2 μs, to study possible changes in bending angle and channeling efficiency due to thermo-mechanical stresses in case of accidental irradiation during accelerator operation. A comparison between measurements performed before and after the irradiation shows negligible differences concerning the angle and the efficiency in both crystals.
