The miscut angle influence on the future LHC crystal based collimation system
The paper concerns the future LHC crystal based collimation system. The dependence of collimation efficiency on the muscut angle characterizing nonparallelity of the channeling planes and crystal surface is mainly addressed. We demonstrate that even the preferable positive miscut can increase the nu...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The paper concerns the future LHC crystal based collimation system. The dependence of collimation efficiency on the muscut angle characterizing nonparallelity of the channeling planes and crystal surface is mainly addressed. We demonstrate that even the preferable positive miscut can increase the nuclear reaction rate in the perfectly aligned crystal collimator by a factor of 4.5 in the UA9 experiment. We also discuss the possible miscut influence on the future LHC crystal collimation system suggesting simple estimates for the beam diffusion step, average impact parameter of particle collisions with the collimator and angular divergence of the colliding particle beam portion. |
