One-dimensional simulation of radiation transport in three-dimensional cylinder

In indirect driven inertial confinement fusion experiments, one-dimensional radiation hydrodynamics code is used to simulate radiation transport in material confined in a cylinder and large bias is generated due to two- or three-dimensional lateral effects like energy losses into the cylinder wall. Lateral X-ray radiation losses such as cylinder wall loss and direct leak from the detection holes are simulated through analytical view factor equations and albedo power laws. Modifications are made for a one-dimensional radiation hydrodynamics code MULTI which is successfully used in the simulation of measured hydrodynamic trajectory of X-ray-heated gold plasma and better result is obtained than without taking lateral effect into account, which proves that this modification is practical.
