The project NICA is being constructed in JINR, Dubna to provide collisions of heavy ion beams in the energy range from 1 to 4.5 GeV/u at the luminosity level of 1*10²⁷ cm^-2*s⁻¹. One of the elements in the collider injection chain is BUSTER – a cycling accelerator of ions 197Au³²⁺. The injection energy of particles is 6.2 MeV/u, extraction energy is 600 MeV/u. Two RF stations are to provide 10 kV of acceleration voltage. Frequency range of operation of the stations in the injector chain is from 634 kHz to 2400 kHz. The provisions are made for autonomous mode of operation of the stations in the frequency range of 0.5 – 5.5 MHz at the same accelerating voltage. Amorphous metal rings of Russian production are used in the RF cavities. RF stations are created in the Budker Institute of Nuclear Physics, SB RAS, Novosibirsk. The stations are tested in the operative mode and will be delivered to the customer in October, 2014. Main design features and parameters of RF cavity, power generator and control system of the stations are described in the paper.

CW 100 keV electron RF gun for 40 mA average beam current was developed, built and commissioned at BINP SB RAS. The RF gun consists of normal conducting 100 MHz RF cavity with a gridded thermo cathode unit, CW 16 kW generator with GU-92A tetrode in the output stage and a set of LLRF electronics. The gun was tested up to the design specifications at a test bench that includes a diagnostics beam line. The design features of different components of the gun are presented. Preparation and commissioning experience is discussed. The beam test results are summarized.

Intellectual Controller for RF stations based on CPU module SAMA5D31-CM for Booster of NICA Project is presented. Controller measures magnetic field using induction coil and provides corresponding real-time tuning of frequency according to non-linear law with 20 ums period and better than 2*10^-4 accuracy. Controller also allows setting up and monitoring several parameters of RF stations. The tester module that generates a sequence of events and signals imitating acceleration cycle is alo presented.
