论文摘要
在FTU中，失控电子与金属等离子体的成分的爆炸样相互作用期间，验证后和原位证据有利于产生高速固体灰尘。新鲜生产的固体灰尘是通过高速影响的次级去重新定位壁损伤的来源，导致陨石坑的形成，这已经在专用的轻质枪支冲击测试中复制了。表面分析，多个理论参数和尘埃动力学建模进一步支持了这种对ITER和演示具有潜在重要性的新型机制。
Post-mortem and in-situ evidence is presented in favor of the generation of high-velocity solid dust during the explosion-like interaction of runaway electrons with metallic plasma-facing components in FTU. The freshly-produced solid dust is the source of secondary de-localized wall damage through high-velocity impacts that lead to the formation of craters, which have been reproduced in dedicated light gas gun impact tests. This novel mechanism, of potential importance for ITER and DEMO, is further supported by surface analysis, multiple theoretical arguments and dust dynamics modelling.
