Crystal collimation experiment on 70-GeV proton accelerator
A. G. Afonin, V. M. Biryukov, V. N. Chepegin +8
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 up…

New projects of crystal extraction at IHEP 70-GeV accelerator
A. G. Afonin, V. M. Biryukov, V. N. Chepegin +8
Using channeling in a 5-mm crystal with bending angle of 0.65 mrad, a record high efficiency, over 60%, of particle extraction from accelerator was achieved. The extracted beam int…

Application of bent crystals at IHEP 70-GeV accelerator to enhance the efficiency of its usage
V. I. Kotov, A. G. Afonin, V. M. Biryukov +13
Bent crystal was extracting 70-GeV protons with average intensity 4*10^11 (as measured in external beamline) per spill of 1.6 s duration, in parallel to the simultaneous work of tw…
