本文研究了JET托卡马克装置刮除层（SOL）区边缘局域模（ELM）径向传播的统计特性。ELM事件以1000 m s-1的有效径向速度径向传播。实验结果表明，径向速度和运输事件的大小之间的联系。这表明了平行和径向传输之间的竞争的重要性，以解释偏滤器板上的粒子损失。平行流动显示出一个短暂的增加，在ELMs的外观，提供证据的平行动力学和径向运输之间的耦合。
The statistical properties of the radial propagation of edge localized modes (ELMs) have been investigated in the Scrape-off layer (SOL) region of the JET tokamak. ELM events propagate radially with effective radial velocities in the range of 1000 m s−1. Experimental results show a link between the radial velocity and the size of transport events. This suggests the importance of the competition between both parallel and radial transport to explain particle losses onto the divertor plates. Parallel flows show a transient increase during the appearance of ELMs, providing evidence of a coupling between parallel dynamics and radial transport.
