Electron density fluctuation in JET measured with multichannel reflectometry

G I Kramer, A C C Sips, N J Lopes Cardozo1993年Plasma Physics and Controlled FusionIF 2.2出版社

Electron density fluctuations have been studied with the multichannel reflectometer at JET. Results from three topics are presented: the location of MHD modes, fluctuations during the sawtooth crash and fluctuations before and after the L-mode to H-mode transition. The nonlinear response of the homodyne detection system, used to measure density fluctuations is considered. This can introduce artefacts in the data which should be taken into account in the interpretation of the signals.

電子密度揺動は、JETにおけるマルチチャンネル反射計を用いて研究されてきた。3つのトピックからの結果が提示される:MHDモードの位置、鋸歯状波クラッシュ中の揺動、そしてLモードからHモードへの遷移前後の揺動である。密度揺動の測定に使用されるホモダイン検出システムの非線形応答が考慮される。これはデータにアーティファクトを導入する可能性があり、信号の解釈において考慮されるべきである。
