Progess of Crystal Channeling Technique for Beam Extraction and Collimation at IHEP
We report progress achieved in crystal-assisted slow extraction and collimation of the 70-GeV
proton beam in the U-70 accelerator at IHEP-Protvino. We recently obtained an extraction
efficiency of 85.3±2.8% for a beam of ∼1012 proton directed towards very short crystals
of ∼2 mm length in spills of ∼2 s duration. The experimental data follow very well the
theoretical predictions obtained with Monte Carlo simulations. This success is important to
devise a more efficient use of the U-70 accelerator in Protvino and suggests a possible way
of implementingcrystal-assisted slow extraction and collimation in other machines, such as
the Tevatron, RHIC, the AGS, the SNS, COSY, and the LHC
