A Heat Transport Model Including the Effect of Non-Maxwellian Electron Distribution and Its Application in Laser Produced Plasma

An electron heat transport model is given for studying laser-to-x-ray conversion of inertial confinement fusion. The electron heat flux is derived based on a non-Maxwellian electron distribution, and the behavior of the heat flux is discussed. The effect of the non-Maxwellian electron distribution on inverse bremsstrahlung heating rate and electron-ion heat transfer rate are also included in the present model. The simulation results show that the effects of the non-Maxwellian electron distribution on laser absorption efficiency, laser-to-x-ray conversion efficiency and electron temperature in the coronal region are important.
