  A new proton irradiation facility to study radiation effects in electronics and different materials was constructed at INR RAS linac. The beam intensity range is 107-1012 protons per separate pulses up to 1 uA of average beam current. The energy is adjusted by switching on/off the fields in accelerating cavities and with energy degraders in the range 20-210 MeV. Features of the facility development, in-air operation, diagnostics system, as well as experimental results of beam adjustment and test irradiation are presented.

  Debuncher is to be installed in the present beam line after the LU-20 linac in the light ion injector of the NICA facili-ty. The purpose of the debuncher is to reduce by a factor of up to ten the ion energy spread in the accelerated beam before injection into the Nuclotron. Relative ion speed is 0.1. Split-ring cavity driven from solid state RF amplifier at 145.25 MHz, should provide effective RF voltage up to 200 kV at 4 kW peak RF power. The RF controller allows adjust effective RF voltage for different ions: 58 kV for Z/A=1, 121 kV for Z/A=0.5 and 190 kV for Z/A=0.3. The debuncher cavity is provided with the stepper-motor driven capacitance tuner with 2 MHz tun-ing range.
