| Abstract: | We use an analysical model to Calculate superthcrmal electron energy deposition in the main fuel under different main compressed laser energy conditions in the fast ignition concept. It is conduced: (1) During the fast ignition process, most superthermal electron energy will be deposited near the edge of the main fuel. (2) This energy deposition is the slowing down process for higher main laser energy. |
