Use of a Bent Crystal with a Decreasing Curvature to Increase the Efficiency of the Extraction and Collimation of a Beam in an Accelerator
I. A. Yazynin, V. A. Maisheev, Yu. A. Chesnokov
It has been shown that the use of a bent crystal with a variable curvature radius makes it possible to reduce the fraction of dechanneled particles by an order of magnitude. This e…
Optimizing the Bent Crystal Parameters for High-Efficiency Beam Extraction and Collimation in Circular Accelerators
I. A. Yazynin, V. A. Maisheev, Yu. A. Chesnokov
The efficiency of the beam extraction and collimation systems in circular accelerators with the use of the channeling effect in a bent crystal is determined. The dependences of the…
The UA9 experimental layout
W. Scandale, G. Arduini, R. Assmann +58
The UA9 experimental equipment was installed in the CERN-SPS in March '09 with the aim of investigating crystal assisted collimation in coasting mode. Its basic layout comprises si…
Collimation of a Circulating Beam in the U_70 Synchrotron by Use of Reflections in Axially - Oriented Crystals
A. G. Afonin, V. T. Baranov, M. K. Bulgakov +13
The possibilities of the extraction and collimation of a circulating beam by a new method due to the reflection of particles in crystals with axial orientation were experimentally…
Channeling Radiation of Positrons with Energy in the Region of 100 GeV in Single Crystals
V. A. Maisheev, Y. A. Chesnokov, P. N. Chirkov +5
The process of radiation of 120-GeV positrons moving in a channeling regime in (011) plane of a single crystal was considered. At the beginning on the basis of the theory of nonlin…
Crystal-Assisted Beam Extraction and Collimation at the U-70 Circular Accelerator
A. G. Afonin, V. T. Baranov, S. Bellucci +15
New crystal technique - array of bent strips and a fan-type reflector, based on thin straight plates - have been used for research of extraction and collimation a circulating beam…
