New Projects of Crystal Extraction at IHEP 70 GeV Accelerator

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 intensity was up to 5.2 x 10**11 protons per spill of ~ 0.5 s duration. Also, the first proof-of-principle experiment on ’c...

Sumario: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 intensity was up to 5.2 x 10**11 protons per spill of ~ 0.5 s duration. Also, the first proof-of-principle experiment on ’crystal collimation' was performed where crystal - serving as a scraper - has reduced the radiation level in the accelerator by a factor of two. The measurements agree with Monte Carlo predictions.
