The loss cone imager

The Loss Cone Imager (LCI) instrument package on the US Air Force׳s Demonstration and Science eXperiment (DSX) mission is expected to provide in-situ measurements of energetic charged particles in the Earth׳s radiation belts. The LCI comprises an 18-pixel imaging electron spectrometer known as the Fixed Sensor Head (FSH) and a single pixel, narrow view angle, large geometric factor, charged particle telescope known as the High-Sensitivity Telescope (HST). The LCI is anticipated to be flown in a 6000 km×12,000 km orbit at 42°42° inclination to allow sampling of the inner and outer radiation belts as well as the slot region.
