Summary
The Digital Ion Drift Meter (DIDM), developed by Amptek, Bedford, MA USA, for AFRL, was launched on July 15, 2000 aboard the Challenging Minisatellite Payload (CHAMP) — developed by the GeoForschungsZentrum, Potsdam, Germany into a 421 x 475 km polar orbit. All components and functions of DIDM are performing nominally except for two problems; the immediate loss after launch of one of the two nearly redundant sensors, and an uneven gain evolution of the micro-channel-plate used for the ion detection that has required development of an in-space calibration procedure. This procedure is now complete and we now have reasonable DIDM results for selected periods of the mission, and will soon be extending the new procedure to the entire mission. This paper will review the instrument design, the laboratory and in-space calibration procedures, and present sample results.
