首次在等离子体中进行电子温度调制实验，其特点是强而持久的电子和离子内部传输势垒 (ITB)，在 JET 中使用模式转换方案中的离子回旋共振加热进行了实验。 ITB 被证明是一个局部良好的窄层，具有低热扩散率，其特征是亚临界传输和刚度损失。此外，冷脉冲传播实验的结果表明 ITB 形成存在二阶转变过程。
The first electron temperature modulation experiments in plasmas characterized by strong and long-lasting electron and ion internal transport barriers (ITB) have been performed in JET using ion cyclotron resonance heating in mode conversion scheme. The ITB is shown to be a well localized narrow layer with low heat diffusivity, characterized by subcritical transport and loss of stiffness. In addition, results from cold pulse propagation experiments suggest a second order transition process for ITB formation.
