Abstract

In this report, the generator of intense microwave pulses based on the S-band relativistic magnetron supplied from the linear induction accelerator (LIA) module is presented. The generator provides different modes of operation. The following modifications were made to provide the capability of continuous operation at high repetition rate: 1) The LIA module has the magnetic switch and magnetic pulsed generator for the strip-line pulse forming network commutation and charging. 2) The LIA module power supply system contains three-phase voltage source with the primary storage oscillatory charging, stabilization circuit for the primary storage voltage level, and thyristor commutator. 3) the relativistic magnetron (i) is of increased resistivity to the anode block damage from the anode current electron bombardment, (ii) is adapted to the LIA module voltage pulse shape. 4) The magnetic system of the magnetron (Helmholtz pair) is supplied from the dc current source and made of copper tube of square cross-section with the central hole for cooling water transport. The electromagnet provides the magnetic field of 0.4 T continuously. The installation control system allows one to set the magnitude of the primary storage voltage, number of shots in a burst, and pause between bursts. The repetitively-pulsed relativistic magnetron generates microwave pulses of highly reproducible amplitude and waveform. The peak power of 300 MW in the S-band frequency (2840 MHz. <2% bandwidth) at 45 ns FWHM pulse duration is produced with 400 kV anode voltage and 5 kA current in the continuous operation mode (8 Hz rep-rate frequency), repetitively-pulsed mode (8-80 Hz), and burst mode (80-200 Hz).
