Coupled Electron/Photon Transport in Static External Magnetic Fields

Abstract

The model describes coupled electron/photon transport through extended media in the presence of macroscopic magnetic fields of arbitrary spatial dependence. Collisional transport is accomplished via condensed-history electron Monte Carlo and single-scattering photon Monte Carlo. Production and transport of relevant secondary electrons and photons are included along with electron energy loss straggling. State-of-the-art differential equation solvers are employed in order to obtain the magnetic field trajectories of the electrons. Options are available which allow for transport through variable density media and for switching the field off in regions where transport is collision dominated. Results from selected model applications are also presented.
