- Abstract
- We report the experimental observation of ion heating by the mode-converted ion Bernstein waves (MC IBWs) in tokamak plasmas. The MC IBW is created from the fast waves launched from the high-field-side antenna in the HT-7 tokamak in plasmas consisting of deuterium majority, hydrogen minority and Li-7 ions. Experimental evidence and numerical simulation show that the interaction between the MC IBW and Li-7 ions at the first ion-cyclotron harmonic resonance of Li-7 (i.e. omega = 2 Omega(Li-7)) is the main mechanism for radio-frequency power deposition. By comparing with previous experiments of direct-launch IBW flow drive on tokamaks and existing theories, we hypothesize that this MC IBW and Li-7 interaction also leads to the observed flow drive effect.
