Application of nonlocal transport model to experiment

Our Krook model for nonlocal electron energy transport [1-5] has been developed on solid theoretical grounds. The model is characterized by both some flux limitation and some preheat as was shown for example in the calculation of a spherical implosion [3]. In the present work, we compare results of our model with an experiment performed at the U. of Rochester [6]. Preliminary results indicate that our Krook model does not exhibit any flux limitation for this case. The reduction in pressure -as indicated by the use of an average flux limiter of .07 to reproduce the experimental result at 1015 W/cm2- can be achieved by a combination of several classical effects, namely a reduction in the absorption fraction and taking into account 2D effects. Numerical diagnostics will be presented to support this interpretation.\\[4pt] [1] W.Manheimer (WM), D.Colombant (DC) and V.Goncharov (VG), Phys.
