摘要：

<正> By ECH under a steady Bv field,a closed field equilibrium of a low aspect ratio aslow as R/a=1.4 is spontaneously formed in the LATE device.After the spontaneous formation,the plasma current has increased further up to IP=7.2 kA by 2.45 GHz,30 kW and IP=11 kA by 5 GHz,120 kW,by increasing the microwave power with a slow ramp of Bv for theequilibrium of the plasma loop at larger currents.Both amount to 12% of the total toroidal coilcurrent.ECH/ECCD at 2ud harmonic resonance of EBW supports the plasma.An outline of thetheoretical considerations for the formation process is presented.
