Nuclear Physics Institute develops high power microwave magnetron generators for more than 25 years. Relativistic magnetrons of conventional, inverted, inverted coaxial configurations, magnetrons with external electron beam injection were investigated.

Output parameters of the repetitively-pulsed relativistic magnetron

frequency band	S
peak power	300 MW
-3 dB pulse length	45 ns
Radiation bandwidth	<2%

Relativistic magnetron and compression circuit

Microwave peak power	1200 MW
Microwave pulse length (-3 dB level)	5 ns

Operation modes	Repetition rate	Number of pulses
continuous	0.4-8 pps	unlimited
repetitively-pulsed (pause time ~ burst time)	8-80 pps	104 - 105
burst (pause time >> burst time)	80-320 pps	103
Compact lativistic magnetrons can be used for testing electronic hardware, radar applications, laser pumping, sterilization etc .
