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…
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…
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 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…
Optimization of the parameters in the RHIC single crystal heavy ion collimation
V. M. Biryukov, Yu. A. Chesnokov, V. I. Kotov +2
In the framework of the project to design and test a collimation system prototype using bent channeling crystal for cleaning of the RHIC heavy ion beam halo, we have studied the op…
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…
