Description
Bent crystals, through the phenomenon of channeling, provide compact and passive deflection elements capable of delivering angular kicks equivalent to those of hundreds-tesla magnetic dipoles on selected portions of a beam. They are therefore attractive for a wide range of beam-manipulation tasks in circular proton and ion accelerators, including ion collimation as foreseen for HL-LHC, halo extraction, crystal-assisted focusing and defocusing, and beam-shadowing schemes in the 1-400 GeV range, in which a bent crystal placed upstream of the electrostatic septum slightly pre-deflects a thin slice of the circulating beam to reduce the particle load on the septum wires and thereby lower extraction losses.
We report recent progress in the design, fabrication, and characterization of bent crystals optimized for these applications. Emphasis is placed on curvature control, crystal quality, and high-precision structural diagnostics to ensure reliable and reproducible deflection performance. These developments demonstrate the feasibility and potential impact of crystal-assisted beam steering in future accelerator facilities.
