In PNPI RNC KI a universal center for testing electronic components for the needs of aviation and space and other applications is created on the synchrocyclotron SC-1000 with the proton energy of 1 GeV. The center consists of two protons and one neutron stands for test facilities developed at the PNPI in collaboration with the ROSCOSMOS Interagency Testing Center. The PNPI center is equipped with all necessary systems of diagnostics and monitoring of a beam, installation of targets on a beam. There is an opportunity to vary temperature of exemplars in the wide range. A unique conjunction of proton beams with variable energy 60-1000 MeV and atmospheric like neutron beam with broad energy range (1-1000 MeV) spectrum enable to perform complex testing of the semiconductor electronic devices at the SC-1000 within a single testing cycle.

In this work an axisymmetric diode electron-optical system based on a field emitter is simulated. The field emitter in the form of a thin filament of finite length is located on the flat substrate with the dielectric layer. The anode is a plane. The electrostatic potential distribution was found in an analytical form - in the form of Fourier-Bessel series in the whole area of the system under investigation. The coefficients of Fourier-Bessel series are the solution of the system of linear equations with constant coefficients.

Insulated core transformer (ICT) electron accelerator is an ideal prototype in low energy radiation processing industry, and ICT high voltage power supply is the essential apparatus. Conventional ICT high voltage power supply uses laminated silicon steel sheets as magnetic cores and works at 50 Hz. In a novel design of the ICT high voltage power supply, the magnetic cores made of ferrite material are adopted to increase the frequency and improve the performance. Focusing on the new scheme, the loss calculation of the high voltage power supply was carried out. The loss of ferrite magnetic cores and the windings was analysed and simulated.

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.
