使用类似的实验工具在不同托卡马克（JET、ISTTOK）和仿星器（TJ-II）装置的等离子体边界中研究了密度梯度和粒子输运之间的动态耦合，结果表明湍流事件的大小在最可能的密度梯度附近最小。实验结果被发现与两个截然不同的等离子体湍流和传输模型的结果一致。目前的发现对几种等离子体装置来说都是常见的，表明聚变装置中等离子体传输和梯度之间的自我调节机制的重要性。
The dynamical coupling between density gradients and particle transport has been investigated using similar experimental tools in the plasma boundary of different tokamak (JET, ISTTOK) and stellarator (TJ-II) devices, showing that the size of turbulent events is minimum in the proximity of the most probable density gradient. Experimental results were found to be consistent with results from two very different models of plasma turbulence and transport. The present findings, common to several plasma devices, suggest the importance of self-regulation mechanisms between plasma transport and gradients in fusion devices.
