Simulation calculation for the energy deposition profile and the transmission fraction of intense pulsed electron beamat various incident angles

The incident angles have a heavy effect on the intense pulsed electr on beam energy deposition profile, energy deposition fraction and beam current transmission fraction in material. This article presents electron beam energy deposition profile and energy deposition fraction versus electron energy(0.5-2.0MeV), at various incident angles for three aluminum targets of various thickness via theoretical calculation. The intense pulsed electron beam current transmission fractions versus electron energy(0.4-1.4MeV) at various incident a ngles for three thickness of carbon targets were also theoretically calculated. The calculation results indicate that the deposition energy in unit mass of material surface layer increases with the rise of electron beam incident angle, and electron beam with low
