• By employing a new invertor power supply system, a fully continuous AC tokamak operation with the whole duration of one minute and the frequency of 60 Hz has been achieved in Current Sustaining Tokamak in Nagoya University(CSTN)-AC device. The plasma current with a few milliseconds flat top is ±600A, with the loop voltage of ±6V, the plasma density up to 2×10^<18>m^<-3> and the electron temperature of around 10 eV. Detailed traces of plasma behavior were measured with triple probe method at the current reversal phase where a very short or almost no dwell time was obtained. Major part of dissipated power was identified to be deposited on the inner surface of vacuum chamber. Quite different histories of gas pressure have been observed, depending on the quantity of adsorbed hydrogen on the wall surface.
