Abstract : The Transient Pulse Monitor (TPM), part of the PASP Plus experiment aboard the APEX spacecraft, is designed to detect and characterize electromagnetic transient signals produced by electrostatic discharges on the solar array test modules. This report describes the results of the TPM post-mission data analyses performed for periods when the various test arrays were biased negatively with respect to the spacecraft. The report includes a developed filter algorithm for distinguishing between actual array discharges and electrical transients produced by other onboard sources, a discussion of the probabilities and characteristics of discharges (based on the filter algorithm) as functions of bias voltages and plasma densities, the results of efforts to determine more precise discharge locations, and a brief description of the TPM instrument.
