Abstract

The results of development, creation, and use of a unified crystal station (CS) at the U-70 accelerator complex are presented. This station is used for proton beam extraction directly from the U-70 accelerator vacuum chamber using the channeling effect. The station performs fine angular and linear movements of crystal deflectors under harsh operating conditions: in a cyclic variable magnetic field of the accelerator, in high vacuum, and at high radiation dose rates. The components of the unified CS and their interrelation are described in detail. An automated control system for the unified CS is presented. The advantages of the unified CS over the previous generation CS are shown. The results of the unified CS operation with proton beams in U-70 sessions are presented.
