Enhancement of the FIDA diagnostic at ASDEX Upgrade for velocity space tomography

M Weiland, B Geiger, A S Jacobsen, M Reich, M Salewski, T Odstrčil, the ASDEX Upgrade Team2016年Plasma Physics and Controlled FusionIF 2.2出版社

Recent upgrades to the FIDA (fast-ion D-alpha) diagnostic at ASDEX Upgrade are discussed. The diagnostic has been extended from three to five line of sight arrays with different angles to the magnetic field, and a spectrometer redesign allows the simultaneous measurement of red- and blue-shifted parts of the Doppler spectrum. These improvements make it possible to reconstruct the 2D fast-ion velocity distribution from the FIDA measurements by tomographic inversion under a wide range of plasma parameters. Two applications of the tomography are presented: a comparison between the distributions resulting from 60 keV and 93 keV neutral beam injection and a velocity-space resolved study of fast-ion redistribution induced by a sawtooth crash inside and outside the sawtooth inversion radius.

ASDEX UpgradeにおけるFIDA(高速イオンDα)診断装置の最近のアップグレードについて論じる。本診断装置は、磁場に対して異なる角度を持つ3つの視線アレイから5つに拡張され、分光器の再設計により、ドップラースペクトルの赤方偏移成分と青方偏移成分の同時測定が可能となった。これらの改良により、広範囲のプラズマパラメータ条件下で、FIDA測定からのトモグラフィー逆変換による2次元高速イオン速度分布の再構成が可能となった。トモグラフィーの2つの応用例を示す:60 keVと93 keVの中性粒子ビーム入射から生じる分布の比較、およびサブトゥース反転半径の内側と外側におけるサブトゥースクラッシュによって誘起される高速イオン再分布の速度空間分解測定である。
