The feasibility of an integral, high temperature, pulse forming network PFN operating at a high pulse rate for a short duration burst has been demonstrated. The dielectric construction of the capacitors consisted of Kapton film and paper impregnated with Monsanto Chemical Co. MS 1489 oil. Litz wire coils were wound on a high temperature foam core and the entire assembly was placed in a stainless steel enclosure. A U-shaped aluminum shield was used between the coils and the case to reduce eddy current heating. An overall weight of approximately pounds for an energy storage density of 600 joules 30 joules per pound was achieved in a design that operated for 150,000 shots at a pulse rate of 280 shots per second in 18 second bursts. The burst duration was limited by heating of the stainless steel enclosure due to eddy currents induced by the coil magnetic field. An aluminum case construction would greatly reduce this effect.
