| Abstract: | A Monte Carlo code is developed to study mega-electron-volt(MeV) electron scattering and transport in plasma based on multiple scattering.A scaling law relating the angular width of a scattered beam to the incident electron energy and the areal density of plasma is found,which may provide a method of MeV electron radiography for diagnosing the areal density of high-temperature,dense plasma under fusion conditions.The study on the MeV electron beam radiography also shows that plasma density interfaces could be discriminated by electron scattering. |
