The radiation transport through a ring slot in a rotation body

A process of the radiation propagation through the orifices in an envelope and reradiation from covers (walls) as well as me influence of screens from optically nontrasparent materials is of interest in the problem of controlled thermonuclear fusion (CTF) for the targets of “Green House” [1] and other types. A model problem of heating an optically wide slab with a slot in optically more transparent medium is under consideration according 2D technique [2]. The coefficients of this task are constructed on the base of the Fleck problems [3]. Just as in [2], we aren't yet taking into account the media motion. Moreover some additional theoretical aspects of the technique [2] are considered. Since the article is a continuation and supplement of [2], all designations of the latter article are kept.
