Volume reflection of high-energy protons in short bent crystals

Characteristics of volume reflection for high-energy protons in short bent crystals are considered by simulation. The deflection efficiency and angle depend on the bend radius of the crystal. The concurrent process of volume capture of particles into channeling states limits the reflection efficiency. The optimal parameters of a crystal for using it as a beam reflector were determined. It was shown that the deflection efficiency of high-energy proton beams by the sequence of reflections in short bent crystals is high for small deflection angles. This allows considering possible applications of crystal reflectors for the beam collimation of hadrons colliders and for high-energy physics experiments.
