2720 Energetic Particles: Trapped, 2774 Radiation Belts
Scientific paper
Maps of the South Atlantic Anomaly (SAA) and high-latitude cutoff rigidities for energetic protons detrimental to satellite operations have previously been produced by the Space Vehicles Directorate of the Air Force Research Laboratory (AFRL/RVBXR) and others. AFRL has since recognized a need for a similar application to detail Low Earth Orbit (LEO) energetic electrons that might also negatively impact operational systems. Current work on this effort, specifically dealing with the outer radiation belt, will be presented. A set of flux intensity maps for electrons is shown for the epoch 2000-2006, based on data from the Compact Environment Anomaly Sensor (CEASE) flown onboard the Tri-Service Experiment-5 (TSX-5) satellite in a 410 km x 1710 km, 69 degree inclination orbit. To eliminate any proton contamination, >10 MeV particles and all particles in the SAA have been removed from the data. Scatter plots of counts/sec versus magnetic latitude are examined to ensure only data for the outer radiation belt is being used. Intensity maps of the integral flux in latitude versus altitude for seven of the instrument channels (0.11 MeV to 6.46 MeV energies) have been constructed. These maps are then compared to the AE-8 and average CRRESELE values and distribution functions examined.
