摘要: [1] The Cute-1.7+APD II, 10 × 15 20 cm3 in size and 5 kg mass, is the third picosatellite developed by students at Tokyo Institute of Technology. One primary goals II mission to validate use avalanche photodiodes (APDs) as a radiation detector for first time space experiment. While itself immature compared forefront satellites plasma physics, APDs offers various possibilities regarding brand-new electron energy analyzer medium-energy electrons ions (1–100 keV), well high-performance light sensor future X-ray astronomy missions. The satellite was successfully launched ISRO PSLV-C9 rocket on 28 April 2008 has since been operation more than year. carries two reverse-type monitor distribution low-energy particles (mainly protons) down 9.2 keV trapped low Earth orbit (LEO), including South Atlantic Anomaly (SAA) aurora bands. We present design parameters preflight tests prior launch, particularly, high counting response active gain control system mission. Examples electron/proton distribution, obtained continuous 12 h observations, will be presented demonstrate initial flight performance orbit.
