偏滤器中的不透明度效应，特别是莱曼线的不透明度效应，被认为与等离子体光谱学和整个偏滤器动力学有关，可能通过激发氢原子的重新分布和辐射损失。已经开发了相当精细的计算辐射输运工具，专门用于许多应用。聚变研究的任务一直是适应聚变边缘等离子体条件。在本文中，我们从已经很好地适应偏滤器应用的现有动力学中性粒子代码开始，并将其从“粒子”模拟扩展到模拟“光子气体”模拟。它示出了如何可以实现，并且可以方便地获得一个相当灵活和详细的偏滤器辐射输运代码。我们应用这一点来研究莱曼不透明度的人口动力学和氢偏滤器辐射损失的影响。本文计划发表在第7期《血浆物理学》上。控制。融合。要访问EFDAJET先进托卡马克研究的特刊，请访问此链接：http://stacks.iop.org/0741-3335/44/7
Opacity effects, in particular of Lyman lines, in divertors are believed to be relevant for plasma spectroscopy and for the overall divertor dynamics through possible redistribution of excited hydrogen atoms and radiation losses. Quite elaborate computational radiation transport tools have been developed, specialized for numerous applications. The task in fusion research has been adaptation to fusion edge plasma conditions. In this paper, we start from an existing kinetic neutral particle code already well adapted to divertor applications, and extend this from the ‘particle’ simulation to an analogue ‘photon gas’ simulation. It is shown how this can be achieved and that a quite flexible and detailed divertor radiation transport code can conveniently be obtained. We apply this to study Lyman opacity effects on population kinetics and hydrogen divertor radiation losses. This article was scheduled to appear in issue 7 of Plasma Phys. Control. Fusion.
