Powerful terahertz g yrotrons based on pulsed magnets

Abstract

A bstract: The terahertz radiation has been demonstrated in pulse gyrotrons. Pulsed coils with field intensity up to 50T have been developed and tested. After more than 3500 shorts no any variation at solenoid operation observed. The repetition rate one short per minute was limited by coil cooling. The output power 5 kW at 1 THz and 0.5 kW at 1.3 THz has been obtained with pulse duration 40 microseconds at the fundamental harmonic with 30 kV/5A electron beam. The design of a sub-THz sub-MW gyrotron has been presented.
