Preliminary design of the energy system for the ZTH experiment

A 4 MA reversed field pinch experiment, called ZTH, is being designed and built at Los Alamos. The first plasma discharges are scheduled to take place in FY 1991. Major electrical power equipment components, such as a pulsed generator, controlled power supplies, isolation and opening switches, current interrupters and capacitor banks are being designed and procured for this experiment. In this paper the requirements and the design philosophy of the components for the energy system are described, and a status report on the component acquisition is given. 7 figs.
