Space Systems Environmental Interaction Studies
Abstract
Under Task 1, the Photovoltaic Array Space Power Plus Diagnostics PASP Plus experiment, encompassing most of Amptek's effort in the report period, Amptek has: (1) designed and built the experiment Controller; (2) provided an Electrostatic Analyzer (ESA), two QCMs, and three calorimeters (CALs); (3) worked with PL/GPSP on testing and integrating PASP Plus into the APEX satellite; and (4) provided Ground Support Equipment for spacecraft integration and mission operation. The Controller is comprised of a central processing unit, an array biasing and electrometer unit, an array I-V curve measurement unit, a power conversion unit, and interfaces to the 16 array modules, ten PASP Plus instruments (not including the Dosimeter), and the APEX spacecraft. The PASP plus Controller and ten other instruments it controls Sun Sensor, Langmuir Probe, ESA, Transient Pulse Monitor (with sensors), Electron Emitter, 2 QCMs, 3 CALs are described in detail, giving size (dimensions), weight, data rates and outputs, and input power requirements. On Tasks 2 and 3, at a much lower level of effort, Amptek supported PL/GPSP's work on the Charge Hazards and Wake Studies CHAWS experiment (O to -5000 V sweep power supply and engineering assistance) and on the S co Wave Interactions with Plasmas Experiment SWIPE (instrument definition)....
