Electron cyclotron emission measurements on TJ-II stellarator plasmas

E de la Luna, I Garcı́a-Cortés, V Tribaldos, F Tabarés, B Zurro2001年Fusion Engineering and DesignIF 1.7出版社

AbstractElectron cyclotron emission (ECE) measurements are used to investigate the changes in the electron temperature profile during on axis and off axis EC-heating in TJ-II stellarator. The modifications of the electron temperature profiles are discussed and compared with the predictions of ray tracing calculations. Recently, the two gyrotrons (PECRH ≤600 kW) were simultaneously applied for the plasma heating in TJ-II. ELM-like events are clearly observed in these plasmas. A first description of these phenomena is also presented.

電子サイクロトロン放射(ECE)測定を用いて、TJ-IIステラレータにおけるオンアクシスおよびオフアクシスEC加熱時の電子温度分布の変化を調査した。電子温度分布の変化について議論し、光線追跡計算による予測と比較した。最近では、2本のジャイロトロン(PECRH ≤600 kW)を同時にプラズマ加熱に適用した。これらのプラズマにおいてELM様事象が明確に観測された。これらの現象の最初の記述も提示する。
