Relativistic Electron Fluid Simulation and Studies on Electric Shock Wave Formation

抄録

This study simulates the scenario when a relativistic electron beam enters high-density plasmas under the fast ignition condition. A relativistic fluid simulation code was developed for simulating relativistic electron transport in high dense plasmas. It is found that a shock wave is formed in a two temperature electron plasma. Namely an electron acoustic mode exists in the two component electron plasma. When relativistic electrons enter high-density plasmas at the relativistic electron expansion front, a shock wave front is formed in our simulation results. This shock wave in the simulation satisfies the relativistic Rankine–Hugoniot condition and Mach number condition.
