Description
A hot electron ring of 4 ∼ 5 cm radius was established on MM-2 simple mirror through ECRH of 15 kW, 15GHz microwave injection. The suppression of hot electron ring on low frequency fluctuations in plasma has been observed experimentally. It can be inferred from the burst, moment of those fluctuations that the ring can exist about 10 ∼ 15 ms after cutting off the microwave injection, even the X-ray radiation from hot electron can insist for 50 ∼ 70 ms. The preionization of H2 will expend the beginning 2 ms of microwave pluse. The optimum background hydrogen pressure is 1.2 x 10-3 Pa to establish the hot electron ring if 15 kW microwave is injected for 9 ms
