Solid targets irradiated by very high intensity laser pulses are dominated by suprathermal electrons with energies of 100s of keV. The penetration of suprathermal electrons into the target is limited primarily by electric and magnetic fields, the growth of which is heavily influenced by the target resistivity which in turn is heavily influenced by ohmic heating of the thermal electrons to keV temperatures. The proposer has developed an implicit 2-D Fokker-Planck code with magnetic field. This code will be the first to self-consistently model all the important physics of suprathermal electrons. We will use the code, as we have used our hybrid code, to model unusual transport phenomena discovered by our collaborators in experiments in RAL. With laser intensities expected to rise by further orders of magnitude during the course of the project, we are confident that there are further transport surprises in store.A parallel strand to the research is to develop FP codes to the point at which they provide a serious alternative to PIC codes as plasma workhorse simulations. This is particularly relevant to lower temperature (industrial) plasmas for which collisional and ionisation physics are important and pose serious problems for PIC simulations.
