One of the most important issues in inertial confinement fusion (ICF) is to study the uniformity of the radiation field around the implosion pellet containing fuel.To this end,a numerical method linking Monte Carlo with iteration method is presented for calculating the radiation transfer problems in a cavity.The detail of the calculation scheme is described and some numerical examples are also given. 相似文献

1. IntroductionX-r8y spectroscopy can provide much informationabout the plasma parameters, and it is often usedas a diagnostic tool for hot plasmas [1]. Resonancelines, such as Ly a and He cr, are often used for theanalysis of soft xrny spectra from highly--chargedplasmas [2,3,4,5,6], and their adjacent dielectronicsatellite lines are used to investigate the line opac-ity and intensity distribution of these resonance Iines[7,8,9,l01. In fact, dense plasmas produced by a ns-pulsed laser are op… 相似文献
