Re-START: The second operational test of the String Thermionic Assembly Research Testbed

“…The objectives of this second test, called "Re-START," were to evaluate the structural integrity of the reengineered diode mounting assembly at high temperatures, measure the output power and current-voltage (I-V) response of the diodes under a variety of thermal and electrical transient conditions, and provide an operational database for use in the development of the ISUS power management and distribution (PMAD) system (Baez 1997).…”

Re-START: The second operational test of the String Thermionic Assembly Research Testbed

“…Driven by the need to evaluate the effectiveness of the new diode support structure prior to the system-level Engine Ground Demonstration (EGD) test, Phillips Laboratory and the Defense Special Weapons Agency jointly decided to perform a second test on the ISUS bimodal system prototype diode array. The objectives of this second test, called "Re-START," were to evaluate the structural integrity of the reengineered diode mounting assembly at high temperatures, measure the output power and current-voltage (I-V) response of the diodes under a variety of thermal and electrical transient conditions, and provide an operational database for use in the development of the ISUS power management and distribution (PMAD) system (Baez 1997).…”
