Collective stopping and ion heating in relativistic-electron-beam transport for fast ignition
Filamented transport of laser-generated relativistic electron beams in a plasma is studied with reference to fast ignition of fusion targets. The study is based on transverse two-dimensional particle-in-cell simulation. Coalescence of current filaments and related ion dynamics are found to determine beam stopping and ion heating.
