Space applications of the MITS electron-photon monte carlo transport code system

Kensek, R.P.; Lorence, L.J.; Halbleib, J.A.; Morel, J.E.

The MITS multigroup/continuous-energy electron-photon Monte Carlo transport code system has matured to the point that it is capable of addressing more realistic three-dimensional adjoint applications. It is first employed to efficiently predict point doses as a function of source energy for simple threedimensional experimental geometries exposed to planar sources of monoenergetic electrons up to 4. 0 MeV due to simulated uniform isotropic fluences. Results are in very good agreement with experimental data. It is then used to efficiently simulate dose to a detector in a subsystem of a GPS satellite from the natural electron environment, employing a relatively complex model of the satellite. The capability for survivability analysis of space systems is demonstrated, and results are obtained with and without variance reduction. © 1996 IEEE.
