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…
