![عکس صفحه اول مقاله: Intermittent transport in the JET far-SOL Intermittent transport in the JET far-SOL](/preview/png/1567567.png)
The intermittent transport in the JET scrape-off layer has been investigated using a multi-pin reciprocating Langmuir probe system. It was found that radial transport in the far-SOL is not continuous but occurs in short bursts observed most often at the beginning of each structure. The magnitude of the parallel ion flux during the filaments quickly decreases with radius, contrary to the cross-field velocity which has a weak radial dependence. Data from the JET boundary plasma have been analyzed to characterize the properties of the intermittent events. Statistical analysis reveals that the filament duration is larger on average in L-mode when compared to that observed during ELMs, while the radial velocity and the density perturbations are smaller.
