Abstract

In this paper, we present a study on DH ( ⁷Li) plasmas with moderate hydrogen concentration (15%) on the HT-7 tokamak. Enhanced density fluctuation induced by ion cyclotron range of frequencies (ICRF) at the centre of the plasma is observed by a continuous wave CO ₂ (λ = 10.6 μm) collective scattering system. At the same time, the Doppler shift V _D due to E ^→ × B ^→ plasma rotation in the mode-converted ICRF DH ( ⁷Li) plasmas is observed experimentally for the first time on the HT-7 tokamak, and the Doppler shift V _D is approximately linear versus the change in plasma stored energy ΔW.
