R which have penetrated a considerable layer of absorbing material in the laboratory. If such particles w'ere produced by an exchange process, their detection would depend on the life of the neutral particle and the frequency of occurrence of the exchange. Recently de Vos and du Toit~reported an effect which

A b s t r a c t -Apulse power supply has been designed to support the development and evaluation of candidate propellants for an Electrothermal Chemical (ETC) gun program a t ARDEC.The flexibility needed for this evaluation is achieved through the modular design of the test fixture and power supply.The test fixture is comprised of a plasma chamber and instrumented combustion chamber interconnected by a convergent-divergent nozzle.The combustion chamber is terminated by an exhaust nozzle and overall thrust is measured. The volume of both c h a m b e r s a n d nozzle configurations c a n be v a r i e d t o optimize performance. A 10 mm gun tube is an option. The power supply is readily reconfigured to provide either an RLC or PFN discharge.Either configuration can store up to 34 kJ and provide a pulse between 0.5 to 2 ms. Load behavior and the effects of parasitic energy losses on circuit performance are presented.The results will be compared with PSpice c i r c u i t models.A presentation of the experimental pulse power system and resulting data will be provided.
