3D Monte-Carlo model to study the transport of hot electrons in the context of inertial confinement fusion.Part Ⅰ
文献摘要：
We describe the development of a 3D Monte-Carlo model to study hot-electron transport in ionized or partially ionized targets,considering regimes typical of inertial confinement fusion.Electron collisions are modeled using a mixed simulation algorithm that considers both soft and hard scattering phenomena.Soft collisions are modeled according to multiple-scattering theories,i.e.,considering the global effects of the scattering centers on the primary particle.Hard collisions are simulated by considering a two-body interaction between an electron and a plasma particle.Appropriate differential cross sections are adopted to correctly model scattering in ionized or partially ionized targets.In particular,an analytical form of the differential cross section that describes a collision between an electron and the nucleus of a partially ionized atom in a plasma is proposed.The loss of energy is treated according to the continuous slowing down approximation in a plasma stopping power theory.Validation against Geant4 is presented.The code will be implemented as a module in 3D hydrodynamic codes,providing a basis for the development of robust shock ignition schemes and allowing more precise interpretations of current experiments in planar or spherical geometries.
