通过注入15kW、15GHz的微波进行电子回旋共振加热,在MM-2简单磁镜中建立了热电子环。电子环半径约为4～5cm。实验观察到了电子环对低频扰动的抑制作用。从低频扰动的再次爆发可推测在微波关断以后热电子环仍可存在10～15ms,而表征热电子存在的X射线辐射可延续50～70ms。微波启动的头2ms的主要作用是电离工作气体,在15kW、9ms微波注入 的实验条件下,建立热电子环的最佳充氢气压为1.2×10~(-3)Pa。
By injecting 15kW, 15GHz microwave electron cyclotron resonance heating, the MM-2 simple magnetic mirror to establish a hot electron ring. Electronic ring radius of about 4 ~ 5cm. The effect of electronic ring on the low-frequency disturbance was observed experimentally. It can be inferred that the thermal electron ring can still exist for 10-15ms after the microwave is turned off, and the X-ray radiation that characterizes the existence of the thermoelectrics can last for 50-70ms. The main role of microwave initiation is to ionize the working gas for the first 2ms. Under the experimental conditions of 15kW and 9ms microwave infiltration, the optimum hydrogen pressure for establishing the thermionic ring is 1.2 × 10 ~ (-3) Pa.
