Abstract
Studies of ECRH-assisted start-up in the CLEO Tokamak have resulted in the production of well-controlled discharges with Ip approximately 13 kA, ne approximately 5*1018 m-3 in the presence of a loop voltage Vl-1, and results in an average rate of current rise of dIp/dt approximately 0.44 MA s-1. Calculated over the whole of the current rise there is a approximately 50% reduction in volt-second consumption when compared with the best case in the absence of RF power. It is estimated that during the plasma current rise approximately 30-50% of the electromagnetic energy input from the poloidal field system is converted to stored magnetic energy.Keywords
