Beam Injection into the Booster of the NICA Accelerating Complex

The NICA accelerator complex includes two chains of linear injectors, a new superconducting Booster, the existing Nuclotron superconducting synchrotron, and a superconducting Collider consisting of two storage rings ≈503 m in circumference. At present, three commissioning runs have been carried out. One of the first operations during work with the beam is its injection and subsequent stable circulation. This paper describes algorithms for tuning a single single-turn injection and the results of the past three runs, as well as methods for optimizing tuning.
