Fusion Plasma Research
Disruption Control Study
Suppression of magnetic field fluctuations causing disruption by local heating with electron cyclotron (EC) waves

EC wave antennas in the JFT-2M vacuum vessel
Leading achievement of disruption control by EC heating
ITER physics R&D issue for achieving high β

For more efficient suppression, a new mirror antenna for current drive (variable injection angle) was developed. The experiment is going on.
