Space Radiation Environment and Shielding Computer Codes. Volume I.
Abstract
Mathematical representations and computer codes are developed for determining the absorbed dose and the linear-energy-transfer spectrum at arbitrary points within a spacecraft on an arbitrary trajectory in space. The radiation environment, including spectral, angular, and temporal dependence, was represented mathematically, and calculation of the flux and flux rate of each particle type was coded. Specifically, codes were devised to (1) determine the spacecraft trajectory; (2) convert the trajectory in geographic coordinates to magnetic coordinates B, L. and t and to equivalent magnetic dipole coordinates R, lambda, and t; (3) calculate the unit-flux dose or total dose of penetrating and secondary radiation at a dose point within the spacecraft; and (4) integrate the various subroutines and instruct a plotter to plot program output.
