Simulation of Electron-Beam Generating Plasma at Atmospheric Pressure

As electron-beam generating plasma is widely applied, the software tool EGS4 (Electron-Gamma Shower) was used to simulate the transmission and energy deposition of electron-beam in air. The simulation results indicated that the range of the electron-beam was inversely proportional to the gas pressure in a wide range of gas pressure, and the electron-beam of 200 keV could generate a plasma with a density 10 11 cm −3 in air of 1atm. In addition, the energy distribution of the beam-electron and plasma density profile produced by the beam were achieved.
