摘要: The design, development, and performance of Medium-energy Electron SPectrometer (MESP), dedicated to the in situ observation suprathermal electrons auroral ionosphere, are summarized this paper. MESP employs a permanent magnet filter with light tight structure select proper energies guided detectors. A combination two avalanche photodiodes large area solid-state detector (SSD) provided 46 total energy bins (1 keV resolution for 3−20 range APDs, 7 >20 SSDs). Multi-channel ultra-low power application-specific integrated circuits also verified flight operation read-out analyze signals. was launched from Poker Flat Research Range on 3 March 2014 as part ground-to-rocket electrodynamics-electrons correlative experiment (GREECE) mission. successfully measured precipitating 120 120-ms time characterized features suprather...
