Modified formula of nonlocal electron transport in a laser-produced plasma
Abstract
A nonlocal heat-transport formula for electrons is derived to include the terms associated with the electrostatic potential and [partial derivative]/[partial derivative][ital v]([ital f][sub 0],[ital f][sub 1]) in the Fokker-Planck (FP) equation. Then the FP equation for a strongly inhomogeneous plasma is solved. It is found that the behavior of the electron thermal conductivity at a large temperature gradient is considerably affected by the electrostatic field, and the thermal conductivity [kappa]/[kappa][sub SH] for electrons scales as 1/[ital k] in a large temperature gradient [ital k] when there exists a non-negligible electrostatic field, where [kappa][sub SH] is the Spitzer-Haerm heat coefficient.
