Pulsed Microwave Source Utilizing an All Solid State Driver for the Generation of Time-Modulated ECR Plasmas

Abstract

An inexpensive pulsed microwave source has been developed for time-modulated electron cyclotron resonance (TMECR) plasma studies. Utilizing series IGBT switching, a high voltage modulator drives a standard 2M130 magnetron producing microwaves at 2.45 GHz. The microwave power waveform follows the TI L modulator trigger 2-500 micro(s) in width, at rep-rates up to 10 kHz and duty factors to 50%. Preliminary measurements of the TMECR plasma potential as a function of microwave pulsewidth, rep-rate, and duty factor are presented.
