Bent crystals for efficient beam steering of multi TeV-particle beams

Abstract Charged particle beams can be manipulated by exploiting the channeling phenomenon in 15-eg2373cl bent crystals.Two plate-like crystals, bent by mechanical holders, were manufactured and characterised for such purpose at the Sensor and Semiconductor Laboratory in Ferrara, Italy.An anticlastic curvature was obtained for these crystals, achieving a steering angle of the order of 1 mrad, which is about 20 times larger than the values currently achieved for the bent crystals used in the LHC for collimation experiments.Finally, a Geant4 simulation was performed to study the channeling efficiency for beam deflection with 400 GeV/c and 7 TeV/c proton beams.

Such crystals represent technological progress in the development of bent crystals for highly energetic charged particle beams.Indeed, they are designed to impart an angular kick to a 7 TeV/c proton beam with unprecedented high efficiency.Therefore, this study demonstrates the possibility of realizing bent crystals suitable for beam extraction in high-energy hadron accelerators, such as LHC or at the future FCC.A further series of studies should be conducted to evaluate the channeling efficiency equi-jec 6 and the deflection angle of the realized crystals via a charged proton beam.
