The effect of electron initial energy with , it’s distribution function and pre-plasma background temperature on the optimum transport into the dense fuel with the density have been investigated analytically for fast-shock ignition concept. Analytical results indicate that for , coulomb logarithm of charged particle has weak dependency on pre-plasma temperature and it seems that plasma stopping power are approximately independent from background temperature. Therefore, it could be concluded that, pre-plasma temperature is a marginal not a key parameter for electron penetration improvement and the electron penetration may be optimized by decreasing fuel density and increment of electron incident energy. So that, the optimal condition may be of the order of for electron incident energy and for pre-plasma density. Furthermore, investigating the impact of fast ignitor wavelength and electron energy distribution function imply that, electron distribution function is almost independent from background temperature and by considering quasi two-temperature distribution function for electron and fast ignitor wavelength of the order of , optimum penetration could be obtained. Ultimately, analytical results confirmed with the Monte -Carlo code and showed good consistency with simulations.
