在MM-2单磁镜装置上完成了电子回旋共振加热实验。装置中心的磁场强度约为3×10~(-1)T,磁镜比等于2.64:1,磁峰距为60cm,真空室内径为20cm,通过微波辐射耦合到中心平面的真空室而产生等离子体并使之加热。微波功率源是一个振动陀螺仪,它在10ms的脉冲持续时间内产生15MHz频率的30kW的输出功率。当出现反磁性信号时,观察到了硬X射线信号。轫致辐射发射分析表明:热电子温度约为25～30keV,通过多栅能量分析器测得的电子密度约为1.1～3.9×10~(10)cm~(-3)。
The electron cyclotron resonance heating experiment was completed on MM-2 single mirror device. The intensity of the magnetic field in the center of the device is about 3 × 10 -1 T, the magnetic mirror ratio is equal to 2.64: 1, the magnetic peak distance is 60 cm, the inner diameter of the vacuum chamber is 20 cm, and the plasma is generated by coupling the microwave radiation to the vacuum chamber in the center plane Body and make it heated. The microwave power source is a vibrating gyroscope that produces 30 kW of output power at a 15 MHz frequency over a 10 ms pulse duration. When a diamagnetic signal appears, a hard X-ray signal is observed. The results of birefringence emission show that the hot electron temperature is about 25-30 keV and the electron density measured by a multi-gate energy analyzer is about 1.1-3.9 × 10-10 cm -3.
