Final Design and Manufacture of a Modular Sixty Megajoule Pulsed Homopolar Generator Power Supply

The Center for Electromechanics at The University of Texas at Austin (CEM-UT) has designed and built high-energy pulsed homopolar generators (HPG's) since 1972. A 5-megajoule (MJ) disc-type HPG was built and tested in 1974 as a high current source for pulsing toroidal and poloidal fields in tokamak devices. The sucess of this prototype generator led to the design of a system of four 50-MJ, disc-type HPG's to power the Texas Experimental tokamak (TEXT). Although never built, the 50-MJ module for this system became the baseline for the design of the 60-MJ system described here. Final design of the 60-MJ HPG power supply has been completed by Parker Kinetic Designs, Inc. (PKD) of Austin, Texas. PKD is manufacturing the system, and will complete installation in February, 1986. Testing of the system will be completed in April, 1986Center for Electromechanic
