ENERGY-LOSSES OF FAST ELECTRONS IN A BEAM-PLASMA

A method is presented for calculating the stopping power of a plasma t hat is produced by the interaction of a powerful fast-electron beam wi th condensed matter. The contribution of the different processes to th e stopping power is analyzed for the temperature and density of a plas ma ranging from 1 to 100 eV and from 10(-4) to 10(-2) rho(0), respecti vely (rho(0) is the matter density at the normal conditions), in which the energy of the beam electrons ranges from 0.01 to 10 MeV. Energy d eposition in aluminum and copper plasmas is calculated for various pla sma conditions.
