在Rijnhuizen托卡马克等离子体项目中，观察到的核心电子温度的瞬态上升时，氢丸切向注入诱导快速冷却的周边区域。高分辨率汤姆逊散射测量表明，T-e上升与区域1 < q < 2中的大温度梯度有关。该区域作为一个层的瞬态增加热阻率（运输障碍）时，探测调制电子回旋加热的快速热脉冲。
In the Rijnhuizen Tokamak Project plasmas, a transient rise of the core electron temperature is observed when hydrogen pellets are injected tangentially to induce fast cooling of the peripheral region. High-resolution Thomson scattering measurements show that the T-e rise is associated with large temperature gradients in the region 1 < q < 2. This region acts as a layer of transiently increased thermal resistivity (transport barrier) when probed by fast heat pulses from modulated electron cyclotron heating.
