Description

The effect of the filling gas natural convection in the French Laser Mega Joule(LMJ) hohlraum on the target temperature distribution has been studied with a CFD code (Fluent). In order to reduce the temperature nonuniformity around the target, the division of the hohlraum with polymer membranes has been simulated to obtain the optimum division mode. In combination with the correct temperatures of the two cooling rings with a temperature difference of ±0.5 mK between them, the seven gas-division mode can meet the uniformity requirement of cryogenic target in the inertial confinement fusion.
