Parallel flow in the JET scrape-off layer

S K Erents, A V Chankin, G F Matthews, P C Stangeby2000年Plasma Physics and Controlled FusionIF 2.2出版社

Parallel plasma flows with Mach number M≈0.5 have been measured inthe JET scrape-off layer (SOL). These flows show a maximum some 10-20 mmmid-plane outside the separatrix, and decrease towards the separatrix. Theflow reverses when BT and IP are reversed, but is asymmetric aboutzero. A number of possible mechanisms for the observed flow are suggested,including ion Pfirsch-Schlüter flow, ballooning transport, momentumtransfer, reverse flow (ionization driven flow) and co-current toroidalmomentum generated in the SOL by ion ∇ and centrifugaldrifts.

JETのスクレイプオフ層(SOL)において、マッハ数M≈0.5の平行プラズマ流が測定された。これらの流れは、セパラトリックスから中平面で約10〜20 mm外側に最大値を示し、セパラトリックスに向かって減少する。この流れは、BTおよびIPが反転すると反転するが、ゼロに対して非対称である。観測された流れの考えられるメカニズムとしては、イオン・ピルシュ・シュリューター流、バルーニング輸送、運動量輸送、逆流(電離駆動流)、およびSOL内でのイオン∇Bドリフトと遠心ドリフトによるトロイダル方向の同方向運動量生成が挙げられる。
