在JET和MAST中，误差场校正线圈（EFCC）最近已被用于尝试控制I型边缘局部模式（ELM），这对ITER中面向等离子体的组件的寿命构成了主要威胁。使用真空磁模型，它建议，ELM缓解在JET观察到的可能与随机化的磁场在边缘。事实上，ELM缓解的发病被认为是与一定程度的奇里科夫参数配置文件。初始MAST结果显示EFCC的ELMs的效果，再次兼容边缘随机根据建模。专门用于ELM控制的新线圈今年已准备好在MAST上使用，并在此简要介绍。
In both JET and MAST, the Error Field Correction Coils (EFCCs) have been used recently in order to attempt to control Type I Edge Localised Modes (ELMs), which represent a major threat to the lifetime of plasma facing components in ITER. Using vacuum magnetic modelling it is suggested that the ELM mitigation observed at JET could be related to the stochastization of the magnetic field at the edge. Indeed, the onset of ELM mitigation is found to be correlated with a certain level of the Chirikov parameter profile. Initial MAST results are presented which show an effect of EFCCs on the ELMs, again compatible with edge stochastization according to the modelling. New coils dedicated to ELM control are ready for use on MAST this year and are presented here briefly.
