论文摘要
与Tokamaks中的中断和失控电子有关的多种风险的缓解涉及竞争要求。成功要求充分理解每个风险，以便可以做出适当的妥协。在这里，重点是短时磁磁扰动与最接近等离子的结构的相互作用，被分离的铍瓷砖覆盖的毯子模块。该瓷砖表面对扰动和力对结构的力的影响是微妙的。不确定性可以通过瓷砖到瓷砖的短路引入。引入了确定的微妙之处，因为电分离的瓷砖可以充当具有正常成分表面的磁扰动的导电表面。开发了一种将这种确定的微妙的方法包括在等离子体模拟中的实用方法。时间尺度越短，定位越大，尤其是在环形方向上，瓷砖的磁效应就越重要。
Mitigation of the multiple risks associated with disruptions and runaway electrons in tokamaks involves competing demands. Success requires that each risk be understood sufficiently that appropriate compromises can be made. Here the focus is on the interaction of short timescale magnetic-perturbations with the structure in ITER that is closest to the plasma, blanket modules covered by separated beryllium tiles. The effect of this tiled surface on the perturbations and on the forces on structures are subtle. Indeterminacy can be introduced by tile-to-tile shorting. A determinate subtlety is introduced because electrically separated tiles can act as a conducting surface for magnetic perturbations that have a normal component to the surface. A practical method for including this determinate subtlety into plasma simulations is developed. The shorter the timescales and the greater the localization, particularly in the toroidal direction, the more important the magnetic effects of the tiles become.
