The impact of edge localized modes (ELMs) carrying energies of up to 450 kJ on carbon erosion in the JET inner divertor is assessed by means of time resolved measurements using an in situ quartz microbalance diagnostic. The inner target erosion is strongly nonlinearly dependent on the ELM energy: a single 400 kJ ELM produces the same carbon erosion as ten 150 kJ events. The ELM-induced enhanced erosion is attributed to the presence of codeposited carbon-deuterium layers on the inner divertor target, which are thermally decomposed under the impact of ELMs.
通过使用原位石英微量天平诊断进行时间分辨测量，评估了携带高达450 kJ能量的边界局域模（ELM）对JET内部偏滤器中碳侵蚀的影响。内部靶材侵蚀强烈非线性地依赖于ELM能量：单个400 kJ的ELM产生的碳侵蚀与十个150 kJ事件产生的相同。ELM引起的侵蚀增强归因于内部偏滤器靶材上共沉积的碳 - 氘层的存在，这些层在ELM的冲击下发生热分解。
