在JET托卡马克等离子体中的实验观察和陀螺动力学模拟表明，电子尺度不稳定性及其与离子尺度不稳定性的相互作用对电子热输运具有重要作用。由于这些效应在强电子加热和接近边际稳定的离子尺度模式下最大，因此这些发现与ITER等离子体具有高度相关性，具有这两种条件。根据JET实验结果对多尺度效应的陀螺动力学和准线性输运模型进行了评估。
Experimental observations in JET tokamak plasmas and gyrokinetic simulations point to an important role, for electron heat transport, of electron-scale instabilities and of their interaction with ion-scale instabilities. Since these effects are maximized for strong electron heating and ion-scale modes close to marginal stability, these findings are of high relevance for ITER plasmas, featuring both conditions. Gyrokinetic and quasi-linear transport models accounting for multi-scale effects are assessed against JET experimental results.
