21 Nov 2019 | | Abstract: | The Active Monitor Box of Electrostatic Risks (AMBER) is a double-head
thermal electron and ion electrostatic analyzer (energy range 0-30 keV) that
was launched onboard the Jason-3 spacecraft in 2016. The next generation AMBER
instrument, for which a first prototype was developed and then calibrated at
the end of 2017, constitutes a significant evolution that is based on a single
head to measure both species alternatively. The instrument developments focused
on several new subsystems (front-end electronics, high-voltage electronics,
mechanical design) that permit to reduce instrument resources down to ~ 1 kg
and 1.5 W. AMBER is designed as a generic radiation monitor with a twofold
purpose: (1) measure magnetospheric thermal ion and electron populations in the
range 0-35 keV, with significant scientific potential (e.g., plasmasphere, ring
current, plasma sheet), and (2) monitor spacecraft electrostatic charging and
the plasma populations responsible for it, for electromagnetic cleanliness and
operational purposes. | | Source: | arXiv, 1911.9353 | | Services: | Forum | Review | PDF | Favorites | |
