AbstractBroadband density fluctuations and plasma potential profiles are measured with a 2 MeV heavy ion beam probe (HIBP) diagnostic system on the TEXT-U tokamak. Measurements are performed in various locations including the edge and the core, as well as the high and low field side regions of the plasma. Results show a poloidal asymmetry in the core density fluctuation power spectra in which a distinct mode in the frequency range 70–170 kHz is present in the low field side region only. Furthermore, the HIBP provides a direct measurement of the local plasma potential from which the electric field profile across the plasma is inferred. Results showing the poloidal asymmetry as well as the potential and electric field profiles are presented.

TEXTUトカマクにおいて、2MeV重イオンビームプローブ(HIBP)診断システムを用いて、広帯域密度揺動とプラズマ電位分布の測定を行った。測定は、プラズマ周辺部および中心部を含む様々な位置で実施され、さらに高磁場側および低磁場側の領域でも行われた。結果は、中心部の密度揺動パワースペクトルにおいてポロイダル非対称性を示し、70〜170kHzの周波数範囲で明確なモードが低磁場側領域のみに存在することが明らかになった。さらに、HIBPはプラズマ電位の直接測定を提供し、そこからプラズマ全体の電場分布が推定された。ポロイダル非対称性ならびに電位および電場分布を示す結果を提示する。
