FLUID EFFECTS ON INVERSE BREMSSTRAHLUNG

A self-similar electron distribution function for inverse bremsstrahlu ng absorption under planar ablative how is derived from the Vlasov-Fok ker-Planck (VFP) equation. Fluid effects play an important role in the build-up of the steady state and enhance the low-energy part of the d istribution function and the well pronounced tail remains (Uryupin S A et al 1995 Phys. Plasmas 2 3100). It is also found that the Bur limit ation factor is modified, and that the energy of electron carrying dom inant heat (EE-CDH) shifts toward the low-energy region by non-Maxwell ian effects. The EE-CDH is about half as much as that obtained in the Maxwellian case. These features are essential for isentropic compressi on and high gain of targets in laser driven implosion.
