A. G. Afonin, V. T. Baranov, V. M. Biryukov +9
This paper presents the physical background for particle extraction from IHEP accelerator using short bent silicon crystals, analyses the results of the studies, considers in detai…
The Investigations Of Beam Extraction And Collimation At U-70 Proton Synchrotron Of IHEP By Using Short Silicon Crystals
A. G. Afonine, V. T. Baranov, V. M. Biryukov +15
The new results of using short (2-4mm) bent crystals for extraction and collimation of proton beam at IHEP 70 Gev proton synchrotron are reported. A broad range of energies from 6…
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…
