This module traces the trajectories of charged particles through earth's magnetic field. It may be used to visualize exactly how ionizing particles arrive at a spacecraft. For example, you can examine whether trapped protons of a specific energy can exist and can interact with a space system at a point in its orbit.

You can use this module to understand various features of the ionizing radiation environment including the South Atlantic Anomaly, geomagnetic cutoff, east-west effect, Stormer cones, electron horns, offset dipole, magnetic mirroring, and higher-order multipole terms in the field.

The module traces electrons, protons, alphas and other heavy ions. They may be traced either forward or in reverse. You may specify the initial position, direction, and energy of the particle; any magnetic field model and epoch; and the length of the trajectory.

This module rapidly creates a Space Radiation orbit file. You can display it with the [207] Instant Graphics module (see image on this page) and output a text file containing coordinates.
