Aspects of Transport in Laser Produced Plasmas

Abstract

Summary form only given. We have been examining two aspects of transport in laser fusion plasmas. Both have to do with the fact that the mean free path is not necessarily short compared to the gradient scale length. Electrons on the tail of the distribution function can penetrate beyond the gradient scale length. We have devised a Krook model which can be easily incorporated into a conventional fluid simulation. It is more than a flux limit, but less than a full kinetic simulation. In the small mean free path limit, it gives classical theory, and follows departures for classical theorv as the plasma heats up. Results are presented showing the effect of this non local heating.
