AN IMPROVED VERSION OF THE VIEW FACTOR METHOD FOR SIMULATING INERTIALCONFINEMENT FUSION HOHLRAUMS

A modified version of the view factor equations is proposed which impr oves the accuracy of the description of temporal effects in energy red istribution by thermal radiation in cavities driven by power pulses ty pical for inertial confinement fusion (ICF). The method is applied to analyze the process of radiative symmetrization in the simplest type o f closed cylindrical hohlraums heated by two x-ray rings on the sidewa ll of the hohlraum case. Such hohlraums may be used in certain types o f ICF targets driven by ion beams. (C) 1996 American Institute of Phys ics.
