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.
