Abstract

Abstract

The atmospheric electron-beam produced air plasma attracts intensive attentions recently. Based on a Monte Carlo toolkit named Geant4, a model including complete physics processes is established to simulate the passage of the electron beam in air in nonuniform magnetic field. By using the model, the characteristics of the electron-beam produced air plasma are simulated. The results indicate that, the nonuniform magnetic field is effective controlling the trajectories of electron beams and can reduce the beam divergence obviously. The energy spectrum becomes wider with the increase of beam penetration depth and secondary electrons play a significant role in low energy range. Moreover, the magnitude of energy deposition at the outlet of the transportation section is two orders higher than th
