Effects of ICRH on electrostatic fluctuations and particle transport in the boundary plasma of TEXTOR

Direct current (DC) driven and turbulence driven cross-field particle fluxes have been deduced from Langmuir probe measurements during discharges with ion cyclotron resonance heating (ICRH) in the TEXTOR tokamak. Spectral analysis of fluctuations of the floating potential at spatially separated probe pins has been used to determine the velocity associated with the poloidal rotation of the boundary plasma. Characteristics of the turbulence spectra of density and potential fluctuations at the edge during ICRH have been measured and compared with the corresponding spectra during standard ohmically heated discharges. It has been observed that both DC driven and turbulence driven fluxes increase significantly during ICRH. The measured high particle fluxes indicate motion in DC convective cells. The DC convective flux and the turbulence driven flux are partly counteracting.

直流(DC)駆動および乱流駆動の交差磁場粒子フラックスが、TEXTORトカマクにおけるイオンサイクロトロン共鳴加熱(ICRH)を伴う放電中のラングミュアプローブ測定から導出された。空間的に分離されたプローブピンにおける浮遊電位のゆらぎのスペクトル解析を用いて、境界プラズマのポロイダル回転に関連する速度を決定した。ICRH中の端部における密度および電位ゆらぎの乱流スペクトルの特性を測定し、標準的なオーミック加熱放電中の対応するスペクトルと比較した。DC駆動および乱流駆動の両方のフラックスがICRH中に有意に増加することが観察された。測定された高い粒子フラックスは、DC対流セル内での運動を示している。DC対流フラックスと乱流駆動フラックスは部分的に互いに打ち消し合っている。
