Fast Wave Current Drive Study
Improvement of confinement by current profile control and steady-state tokamak operation
Traveling wave antenna (Combline antenna)
Collaboration with General Atomics
- Sharp directivity with 12 current straps
- No need for phase adjustment per individual current strap
Combline antenna installed in the JFT-2M vacuum vessel
Experimental results
- No need for impedance matching from vacuum- to plasma loading
demonstration of fast wave pre-ionization - No problem of mismatching on H-transition and ELMs
Negative shear experiments will be performed in combination with electron cyclotron heating.
