Electric Propulsion Facilities
Space Electric Propulsion Laboratory is equipped with two identical L-shape
vacuum chambers (named MSLC-1 and MSLC-2) that are approximately 0.6 m diameter by 1.5 m long.
|Internal Diameter||0.6 m||0.6 m|
|Length||1.5 m||1.5 m|
|Pumping Speed||2,200 l/s||4,300 l/s|
|Base Pressure||1x10-7 mbar||<1x10-7 mbar| MSLC-1 is currently equipped with a direct
impulsive thrust balance capable of measuring an impulse bit in the range 20 µNs to 120 µNs. The facility has
been used to flight-qualify the first PPT for Cubesat applications and to test a PPT for Nano-satellite applications.
The facility is currently used for delta qualification and acceptance testing
of cubesat PPT Flight Models
is currently used to perform tests on Hollow Cathodes and Hollow Cathode Thrusters, an
d will be used for tests on the Xenon Very High Temperatu Resistojet and Ring Cusp Ion thr
Power Supplies and Measuring InstrumentsDC electric power supplies include both low and high
voltage supplies (up to 15 kV) necessary to operate PPTs and low and high current supplies to run HCs, HCTs, VHTRs and Ring Cusps (up to 60 A).
capabilities include two HV probes (rated up to 12 kV), one HV differential probe
(rated up to 7 kV), two Rogowski coils (to measure the PPT discharge
current) and a high accuracy mass scale with a resolution of 10 µg.
