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.

In 2016 the testing of the first section of the particle accelerator for the European X-ray Free-Electron Laser (XFEL) was completed and the results were excellent. BINP take anticipation in many works of XFEL construction. One of these works is developing, production, system assembling and putting in operation the power supply system for corrector magnets. Since 2012 there were developed, produced and delivered to XFEL 7 models of power supplies with up to 10 A output current and up to 70 V output voltage. Total quantity of delivered power supplies is near 400 pieces. The report presents the structure of power supply system and results of testing.

Hardware-software complex "PIRS-5" was developed to make measurements in warm accelerating structures. The idea was to create full-automatic measuring system, which can measure electrical field at the bead position with non-resonant and resonant pull techniques. PIRS-5 has postprocessor, which calculate electrical component from the frequency, reflection or transmission coefficient, shunt and effective shunt impedance. This work describes the construction of this complex, its mathematical part and possible future modifications.

The Linear Induction Accelerator LIA-20 is being created at the Budker Institute of Nuclear Physics. Waveform monitoring system (WMS) is an important part of LIA-20 control system. WMS includes "slow" and "fast" monitoring subsystems. Three kinds of digitizers have been developed for WMS. "Slow" subsystem is based on ADCx32. This digitizer uses four 8 channel multiplexed SAR ADCs (8 us conversion cycle) with 12-bit resolution. Main feature of this module is program configurable channel sequencing, which allows to measure signals with different timing characteristics. Two types of digitizers are involved in "fast" subsystem. The first one, ADC4x250-4CH, is 4-channel 250 MSPS digitizer. The second one, ADC4x250-1CH, is single channel digitizer with sample rate of 1 GSPS. Resolution of both devices is 12 bit. "Fast" modules are based on the common hardware. This paper describes hardware and software architecture of these modules.
