Deflection of protons under axial channeling in a silicon crystal bent along the <111> axis was observed on experiment with 400-GeV protons at the CERN Super Proton Synchrotron. The deflection efficiency due to axial channeling of protons for the crystal with the bend angle 50 µrad was about 30 %. Axial channeling deflection occurred by means of doughnut scattering and hyper-channeling, this latter involving about 2% of the particles.

Abstract
Deflection of protons under axial channeling in a silicon crystal bent along the <111> axis was observed on experiment with 400-GeV protons at the CERN Super Proton Synchrotron. The deflection efficiency due to axial channeling of protons for the crystal with the bend angle 50 µrad was about 30 %. Axial channeling deflection occurred by means of doughnut scattering and hyper-channeling, this latter involving about 2% of the particles.File in questo prodotto:
