An Algorithm for Matching the Amplitude of the Accelerating Voltage and the Rate of Growth of the Magnetic Field

The preparation of the NICA injection complex for injection into the collider requires an increase in the beam intensity at the Nuclotron exit. Important part of the program to increase intensityis a reduction of beam loss in the course of beam acceleration. This approach requires an optimization of many systems of the facility, and, in particular, of operation of the RF systems. Experience gained in the course of four commissioning runs enables choosing major directions for further optimization of RF systems operation. The measurement showed that the beam losses observed at the beginning of accelerating cycle, in both Booster and Nuclotron, are related to the mismatch between the magnetic field growth rate and capabilities of existing RF systems. Ways to achieve the required matching and the corresponding loss in the accelerating rate are discussed.
