Observation of Mode-Converted Ion Bernstein Wave by an HCN Laser Scattering

概要
- 論文の詳細を見る
An HCN laser scattering technique is employed for detecting an electrostatic wave excited by ICRF heating on the JIPP T-IIU tokamak. The measured wave is consistent with the theoretically estimated wave dispersion of the ion Bernstein wave which is mode-converted from the fast wave near the ion-ion hybrid resonance layer. The ion Bernstein wave is found to be strongly absorbed and damped at least by 30dB as propagating a half round of the torus (2.9m in toroidal direction). The influence of MHD activity on the mode-converted ion Bernstein wave is examined. When the MHD activity grows and the plasma becomes unstable due to high power ICRF heating, the scattered signal from the ion Bernstein wave decreases, being accompanied with large fluctuations.
