论文摘要
在磁融合实验中,一种评估第一壁组件上热通量的简单技术是控制等离子体表面相互作用的关键。热通量可以以峰值因子为特征,峰值因子是峰热通量与平均热通量的比率。可以使用简单的推导和标准软件工具来精确计算峰值因子。该分析应用于在15 MW的启动阶段,在理想化,现实和未对准的情况下,将其用于等离子体壁接触的iTer类实验。即使峰值因素通常高于10,墙上的峰热负载仍以几英里/m $ {}^2 $为中等。
In magnetic fusion experiments, a simple technique to evaluate the heat flux on first wall components is a key to controlled plasma surface interaction. The heat flux can be characterized by the peaking factor which is the ratio of the peak heat flux to the average heat flux. The peaking factor can be calculated exactly using simple derivations and standard software tools. This analysis is applied to an Iter class experiment for plasma wall contact during start up phases at 15 MW, in idealised, realistic and misaligned situations. Even though the peaking factors are usually above 10, the peak heat load on the wall remains moderate at a few MW/m${}^2$.
