Transport of relativistic electron beams in preformed channels

The propagation of a relativistic electron beam, in a reduced density channel consisting of fully or partially ionized gases is analyzed in two ways. First, a relativistic Fokker Planck equation is derived and used to determine the appropriate relaxation times. The relativistic kinematics of high energy collisions are also presented. Next, a computer code, named TREBIC, was written to model the transport of a relativistic electron beam in such media. This code utilizes some of the analytical results mentioned above to simulate electron scattering, and includes the electromagnetic self-fields of the beam. Some results from TREBIC are subsequently presented and discussed
