Three series of recent experiments on JET have been dedicated to energy transport studies. Experiments with pellet injection followed by off-axis ICRH produce a heat sink on axis resulting in an inward thermal heat flux. A diffusive model for thermal flux with no heat pinch can adequately describe the data. It also describes the data from current ramp experiments in which total current is transiently decorrelated from the current distribution. The effective thermal diffusivity in L-mode confinement is found to scale with normalised Larmour radius according to Bohm in a series of non-dimensional scaling experiments.
JET上最近的三系列实验专门用于能量输运研究。通过弹丸注入后接离轴ICRH加热的实验，在轴心产生了热汇，从而形成向内方向的热通量。一个不考虑热缩并的热通量扩散模型能够充分描述这些数据。该模型同样适用于电流爬升实验中的数据，在这些实验中总电流与电流分布瞬态地去关联。在一系列无量纲定标实验中，L模约束下的有效热扩散系数被发现按照玻姆定标律随归一化拉莫尔半径变化。
