Application of Bent Crystals at IHEP 70-GeV Accelerator to Enhance the Efficiency of its Usage

Bent crystal was extracting 70-GeV protons with average intensity 4x10$^{11}$ (as measured in external beamline) per spill of ~1.6 s duration, in parallel to the simultaneous work of two internal targets in the accelerator ring. An additional crystal, placed in the external beamline, was deflecting a small part of the extracted beam with intensity ~10$^7$ protons toward another physics experiment. [...]

The first proof-of-principle experiment on "crystal collimation" was performed with 70-GeV protons on IHEP accelerator. A bent crystal installed in the ring as a primary element upstream of a collimator has reduced the radiation levels downstream in the accelerator by a factor of two. [...]

High Energy Phys., Protvino, Russia) ; Biryukov, V M (Inst. High Energy Phys., Protvino, Russia) ; Chepegin, V N (Inst. High Energy Phys., Protvino, Russia) ; Kotov, V I (Inst.

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 ~10**12 proton directed towards very short crystals of ~2mm length in spills of ~2s duration. [...]
