A Pulsed Magnetron Driver for the Lithium Tokamak Experiment

Eagle Harbor Technologies (EHT), Inc. has designed and built a pulsed magnetron driver that will be delivered to the Lithium Tokamak Experiment (LTX) at the Princeton Plasma Physics Laboratory. Earlier in the program, EHT developed and tested a 10-kV solid-state switch. To build the magnetron driver, EHT has stacked four of the 10-kV switches in series to achieve the 40-kV output. The driver can produce 40 kV for 5 ms and source up to 100 A. The rise time of the output pulse has been tailored for the specific magnetron at LTX. EHT has also developed short-circuit protection that will shut down the magnetron driver in less than 1 \textmu s. EHT will present results of the development of the pulsed magnetron driver during the Phase II program.
