A stand based on a magnetron, circulator, parallel-coupled accelerating structure, electron gun, diagnostic equipment, and modulator has been being created at the Budker Institute of Nuclear Physics (BINP) for testing the accelerator and injection part of a compact linear accelerator. The installation operates in the S-band with a pulsed power of 3–3.5 MW and average magnetron power up to 3 kW. This work contains descriptions and results of preliminary launching of the stand.
