SEPS
The Source/Loss-Cone Energetic Particle Spectrometer (SEPS) instrument is located on the POLAR satellite despun platform along with the auroral imagers, and is independent of the other CEPPAD sensors. SEPS consists of two independent telescopes which measure both the energetic electron, and ion fluxes in the vicinity of the magnetic field-aligned loss, and source cone regions with high sensitivity, and with fine angular and time resolution. SEPS consists of two independent telescopes, one for electrons, and one for ions. The electron telescope has twice the sensor area of the ion telescope, and uses aperture wheels to vary its dynamic range. Particle angular imaging is obtained using pinhole-camera apertures in front of the electron XY position sensitive detectors. The ion telescope is similar to the electron telescope except for the reduced sensor area, and the fact that the aperture wheels are replaced by magnets which sweep out electron. See: http://www.css.tayloru.edu/~physics/seps.html for more information. The SEPS is part of the Comprehensive Energetic Particle Pitch Angle Distribution (CEPPADS) package, but the SEPS sensor is independent of the body mounted sensor and contains a separate digital processing unit.
