Kinetic Simulations of Relativistic Electron Flows in Time-Dependent Electromagnetic Fields

摘要

Relativistic transport equation for approximate distribution function of electron flows is derived from the Vlasov equation in external electromagnetic wave fields. The initial distribution of electrons is considered as the Juttner distribution in the whole configuration space. The distribution function of electrons is approximated by expanding it into a series of static Juttner distributions each multiplied by time-dependent coefficients.
