ENERGY LOSS OF RELATIVISTICELECTRON BEAM IN A MAGNETIZED PLASMA

In the paper,the energy loss of a relativistic electron beam (REB) in magnetized plasma has been investigated We derived the general expression for the energy loss and expanded it in terms of the small parameters.Up to the lowest order,the final analytical expression of the energy loss of REB was obtained.In the absence of an applied magnetic field B0 it reduces to R A.Gerwins result.Finally,we have numerically analyzed the dependence of the energy loss on the parameters.The results shqw that in some parameter range the magnetic field has an important effect on the energy loss of REB.
