EBW studies on the Mega Amp Spherical Tokamak (MAST) can be subdivided into four separate subjects: thermal EC emission observation from overdense plasmas; EBW modeling; proof-of-principle EBW heating experiments with the existing 60 GHz gyrotrons; EBW assisted plasma start-up at 28 GHz. The optimum choice of frequency and launch configuration for EBW heating and CD is a key issue for future applications in MAST. The modelling suggests the preferable operating frequency for efficient EBW heating and CD must be in the range of the fundamental EC resonance or its lower harmonics. This requires a high power RF source in the range of 16–28 GHz. Workplace Institute of Plasma Physics Contact Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Year of Publishing 2007
