用RFEA测量的在MAST中III型和I型ELM期间偏滤器靶处的刮除层离子温度测量
Scrape-off layer ion temperature measurements at the divertor target during type III and type I ELMs in MAST measured by RFEA
摘要：
在未来的核聚变反应堆中，高热负荷事件，如边缘局部模式（ELM），可能会损坏偏滤器材料并将杂质释放到主等离子体中，从而限制等离子体性能。最难处理的是I型ELM，因为它们携带来自等离子体的最大部分能量，因此在靶和第一壁材料上沉积最大的热通量。了解从ELM事件释放的离子的温度是重要的，因为它决定了它们将从面向等离子体的材料引起的潜在溅射。为了在I型ELM期间通过减速场能量分析仪（RFEA）测量Ti，已使用一种新的操作技术来进行更快的测量;这被称为快速扫描技术（FST）。
英文摘要：
In future nuclear fusion reactors high heat load events, such as edge-localised modes (ELMs), can potentially damage divertor materials and release impurities into the main plasma, limiting plasma performance. The most difficult to handle are type I ELMs since they carry the largest fraction of energy from the plasma and therefore deposit the largest heat flux at the target and on first wall materials. Knowing the temperature of the ions released from ELM events is important since it determines the potential sputtering they would cause from plasma facing materials. To make measurements of Ti by retarding field energy analyser (RFEA) during type I ELMs a new operational technique has been used to allow faster measurements to be made; this is called the fast swept technique (FST).
