Abstract :
A 3D study of deep charging in a satellite has been carried out. A complex model. Satellite structure has been assembled via software named “Builder” developed in-house for this purpose, The generated file formed an input file for the code “ACCEPT”, a 3D Monte Carlo electron/photon propagation simulator. The code was run on the 500 MHz DEC Alpha RISC platform. Both low and high fluence conditions affecting the internal charging state of the satellite at GEO have been considered. The approach presented allows analysis of realistic charging scenarios
