Accelerator Tests of Crystal Undulators
V. M. Biryukov, A. G. Afonin, V. T. Baranov +22
A series of Silicon crystal undulator samples were produced based on the approach presented in PRL 90 (2003) 034801, with the periods of undulation from 0.1 mm to 1 mm, and the num…
Crystal experiments on efficient beam extraction
A. G. Afonin, V. M. Biryukov, V. T. Baranov +13
Silicon crystal was channeling and extracting 70-GeV protons from the U-70 accelerator with efficiency of 85.3+-2.8% as measured for a beam of 10^12 protons directed towards crysta…
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…
Progress in crystal extraction and collimation
A. G. Afonin, V. M. Biryukov, V. T. Baranov +13
Recent IHEP Protvino experiments show efficiencies of crystal-assisted slow extraction and collimation of 85.3+-2.8%, at the intensities of the channeled beam on the order of 10^12…
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…
