The Access of Energetic Charged Particles to Satellite Altitudes.
Abstract
The ability of energetic charged particles to arrive at a particular location within the magnetosphere from a particular direction is characterised by the cut-off rigidity for the location and arrival direction. Cut-off rigidities may be obtained either by interpolation between known cut-offs at adjacent sites and/or directions of arrival, or by the numerical integration of appropriate particle trajectories in a suitable numerical model of the geomagnetic field. This report summarizes research on the calculation of cutoff rigidities for a satellite at 400 km altitude. The report is divided into the following sections: General Cut-off Survey, Asymptotic directions of arrival for very high rigidity particles, Cut-off definitions for below-horizon directions, and Largest zenith angle of arrival. A listing of the publications and presentations resulting from this effort is included. (Author)
