MONTE-CARLO (HYBRID) SUPRATHERMAL ELECTRON-TRANSPORT

A one-dimensional hybrid model for electron transport in laser targets is introduced, in which the suprathermal electrons are collisional particle-in-cell particles, the thermal electrons are a donor-cell fluid, and the electric field is calculated by artificially dilating the plasma period. The scheme shows that resistive electric fields are too transient and that a calculated ion-acoustic level is too low to explain experimentally observed reduced transport, that can, however, arise as convective inhibition enhanced by troughs in the target density profile. © 1979 The American Physical Society.
