In November 2013, the FAIR management delegated the responsibility for the technical design, construction, installation, and commissioning of the whole CR and its components from GSI to Budker Institute of Nuclear Physics (BINP). Since that time a lot of modifications of the original design were made aiming to improve the beam parameters and the machine performance. This work shows the present status of the development.

The control system of a linear induction accelerator LIA-20 for radiography is presented in this paper. The accelerator is designed to provide a series of three consecutive electron pulses with energy up to 20 MeV, current 2 kA and lateral size less than 1 mm. To allow reliable operation of the whole complex, coordinated functioning of more than 700 devices must be guaranteed in time frames from milliseconds to several nanoseconds. Total number of control channels exceeds 6000. The control system structure is described and the hardware in VME and CAN standards is presented.

The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

The system of geodetic measurements for accelerator LIA-20 is presented. The system consists of two subsystems. The first one is hydrostatic level system and the second one is system with the stretched wire. The system of geodetic measurements controls vertical and horizontal shifts of the accelerating structures, and also their inclinations in the longitudinal and cross directions.
