论文摘要
灰尘壁高速冲击是由终止在面向组件的血浆中终止的终止，这构成了侵蚀的来源。钨灰尘对散装钨板的正常高速机械影响通过轻型气枪射击系统以受控的方式复制。验尸表面分析表明，实现了三个侵蚀制度。塑性变形，粘结和部分崩解。较大的影响统计数据允许在后一种制度中提取可靠的经验损害定律，这可以用于未来反应堆中的侵蚀估计。
Dust-wall high speed impacts, triggered by the termination of runaway electrons on plasma facing components, constitute a source of erosion. Normal high velocity mechanical impacts of tungsten dust on bulk tungsten plates are reproduced in a controlled manner by light gas gun shooting systems. Post-mortem surface analysis revealed that three erosion regimes are realized; plastic deformation, bonding and partial disintegration. The large impact statistics allowed the extraction of reliable empirical damage laws in the latter regime, which can be employed for erosion estimates in future reactors.
