摘要

In fast wave to ion Bernstein wave mode conversion experiments in DT supershot plasmas,rnlocalized efficient ion heating rather than electron heating was observed, due to Dopplerbroadenedrntritium cyclotron resonance overlap into the mode conversion region. The ionrntemperature heat pulse associated with RF power modulation in this regime could provide arndiagnostic tool for measuring the local ion thermal conductivity in various confinement regimes.rnIn direct-launch ion Bernstein wave heating experiments, core power coupling was limited by thernexcitation of parasitic edge modes. However, a sheared poloidal flow was observed that isrnconsistent in both magnitude and direction with theoretical models based on RF-driven Reynoldsrnstress. With the modest power coupled to the core (~ 360 kW), the magnitude of the observedrnflow was estimated to be a factor of 3-4 too low to trigger transport barrier formation throughrnlocalized shear suppression of turbulence.
