Tested at PEPL
Space Systems/Loral loaned PEPL an SPT-100 Hall thruster to conduct far-field plume measurements to support flight qualification for far use on Western spacecraft. Under Air Force Office of Scientific Research (AFOSR) support, PEPL developed a number plume diagnostics to study the SPT-100 including: a fast radial traverse system to obtain far- and near-field plume measurements (with RPA, Langmuir, heat flux, and neutral density probes), a molecular beam mass spectrometer (MBMS) to characterize the plume plasma charge state, and an ExB probe to quantify the plume plasma charge state.
