PASP PLUS Transient Pulse Monitor (TPM) - Preflight Characterization Report.
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. However, as a result of the way in which the TPM electric-field sensors are installed on the APEX spacecraft, certain additional information is required to properly analyze and interpret mission data relating to the locations of discharges that may occur. The purpose of the TPM E-Field Sensor Response Characterization Test was to perform a series of preflight measurements on the as-installed sensor/payload configuration. The measurements were made to determine the relative combined responses of the entire set of E-field sensors to electromagnetic signals originating at selected locations on the deployed panel and payload shelf. These data will then be used, during the data analysis phase of the PASP Plus program, to help determine the actual discharge locations. This report describes the TPM E-Field Sensor Response Characterization Test results, and, based upon these results, the development and testing of preliminary flight data analysis techniques and software prior to launch Transient pulse monitor (TPM), Preflight characterization of sensor response, arc pulse parameter measurements, High-voltage arc discharge characterization
