Description
Summary
The ICARE instrument was flown on the SAC-C satellite (705 km, 98°, Dec 2000-April 2012). An improved version ICARE-NG was flown on the SAC-D (657 km, 98°, June 2011-June 2015) and the JASON-2 (1336 km, 66°, June 2008-Aug. 2016) satellites and is currently operated on JASON-3 (1336 km, 66°, Jan. 2016-now). The instruments are based on classical detector designs using single and coincident mode detection of energy deposition in Si diodes. An analog to digital conversion over 128 to 256 channels of the pulse height counts allows a quite fine restitution of flux versus energy spectra. The instruments also feature a technology board including 2 dosimeter types, TID and TNID drift measurements, and SEU, SEL, SEB counts over a selection of devices. The development of these instruments in a joint venture between ONERA (detector design and data processing) and CNES (technology board design, instrument development and in-orbit operations). The communication will present the main features of the instruments and the technology boards, and samples of results over periods of interest.
