We present a method of beam emission spectroscopy (BES) using an atomic Li beam that is generated by means of laser blow-off for the investigation of electron density fluctuations in the edge and scrape-off layer plasmas of fusion devices. We discuss the operational limits of this technique and compare them to those of other atomic Li beam diagnostics.Furthermore, we apply this method to different Wendelstein 7-AS discharges and study the influence of the line integrated electron density and the direction of the main magnetic field on the fluctuations inside and outside the last closed flux surface, and especially on their movement.The information we obtain on the influence of the main magnetic field on the fluctuations gives some insight into the possible origin of certain features of their spatial structure.

我々は、核融合装置の周辺およびスクレイプオフ層プラズマにおける電子密度揺動の調査のための、レーザーブローオフによって生成される原子Liビームを用いたビーム発光分光法(BES)の手法を提示する。我々は、この手法の適用限界について議論し、他の原子Liビーム診断法と比較する。さらに、この手法を異なるWendelstein 7-AS放電に適用し、最終閉鎖磁気面の内外における揺動に対する視線積分電子密度および主磁場方向の影響を研究する。主磁場が揺動に及ぼす影響に関して得られた情報は、その空間構造の特定の特徴の可能な起源についての洞察を与える。
