Main-ion temperature and plasma rotation measurements based on scattering of electron cyclotron heating waves in ASDEX Upgrade

We demonstrate measurements of spectra of O-mode electron cyclotron resonance heating (ECRH) waves scattered collectively from microscopic plasma fluctuations in ASDEX Upgrade discharges with an ITER-like ECRH scenario. The measured spectra are shown to allow determination of the main ion temperature and plasma rotation velocity. This demonstrates that ECRH systems can be exploited for diagnostic purposes alongside their primary heating purpose in a reactor relevant scenario.

我々は、ITER類似のECRHシナリオを有するASDEX Upgrade放電において、電子サイクロトロン共鳴加熱(ECRH)波がプラズマ中の微視的揺らぎによって集団散乱されたスペクトルの測定を実証した。測定されたスペクトルにより、主イオン温度とプラズマ回転速度の決定が可能であることが示された。これは、ECRHシステムが、炉心関連シナリオにおいて主たる加熱目的に加えて、診断目的にも利用可能であることを実証するものである。
