Abstract

The loss cone imager (LCI) on the demonstration science experiments mission (DSX) of the Air Force Research Laboratory (AFRL) was designed to measure the effect of waves on non-relativistic electrons in the slot of the radiation belts. The LCI comprises two instruments: a narrow ~7° acceptance-cone electron detector (HST) to measure the low-intensity electron flux in the local loss cone, and a three-pin-hole multi-pixel sensor, the fixed sensor head (FSH), measuring the electron intensity in a 180° x 10° continuous swath containing the HST look-direction at 45°. The design history of the LCI is briefly outlined; the relevant mechanical and signal processing parameters reviewed; and the differential response functions, including the normal data-number (DN) to engineering-unit (EU) conversion of raw data, required to generate the physics (model dependent) parameters discussed.
