Blob transport properties in the plasma edge in the presence and absence of radio-frequency (RF) convective cells are compared. For the first time, the interactions between RF convective cells and intermittent plasma blobs in the scrape-off layer (SOL) are observed with gas puff imaging in the ASDEX Upgrade tokamak. It is found that the RF convective cells induce a sheared flow in the far SOL, which is able to stretch, distort and even split the blobs poloidally. The observed phenomena indicate that an externally generated sheared flow in the SOL can be considered as a method to modify blob transport in a favorable way.

プラズマ端部におけるブロブ輸送特性を、高周波(RF)対流セルの存在下と非存在下で比較した。ASDEX Upgradeトカマクにおいて、ガス入射イメージングを用いて、RF対流セルと間欠的ブロブとの相互作用が初めて観測された。RF対流セルは遠スクレイプオフ層(SOL)にせん断流を誘起し、このせん断流がブロブをポロイダル方向に伸長、変形、さらには分裂させることができることが見出された。観測された現象は、外部から生成されたSOL内せん断流が、ブロブ輸送を好ましい方向に改変する手法として利用可能であることを示している。
