Abstract:
Closed loop control of the period of Fast Ion Stabilised Sawtooth has been demonstrated for the first time on Tore Supra by varying the ECCD injection angles in real time. Fast ions generated by 4 MW of central ICRH increased the Sawtooth period to 100 ms. This sawtooth period was reduced to the ohmic period of 30 ms by the addition of only 300 kW of ECCD near the q = 1 surface. A feedback loop allowed the sawtooth period to be switched in real time between short and long sawteeth with a response time of ~1 s.
