给出了在简单磁镜装置MM-2及其改进装置MM-2U中电子回旋共振加热(ECRH)和离子回旋共振加热(ICRH)的实验结果。在电子回旋共振加热的实验中,使用一个频率为15GHz,功率约为30kW的微波源,建立了热电子温度为140~170kev的热电子环,这是半径为7~10cm,空间分布为一个非封闭的环。在离子回旋共振加热实验中,使用一个频率为4.81MHz,功率为40kW的射频源,对ECR等离子体进行离子回旋共振加热,观测到离子与电子受到了不同程度的加热,离子温度由原来的平均3eV升到8eV,电子温度由原来的平均20eV升到30eV,且等离子体电位及等离子体的约束特性均有所改变。
The experimental results of electron cyclotron resonance heating (ECRH) and ion cyclotron resonance heating (ICRH) in the MM-2 and its modification MM-2U are given. In the experiment of electron cyclotron resonance heating, a hot electron ring with the temperature of 140-170kev was established by using a microwave source with a frequency of 15GHz and a power of about 30kW, which is a thermionic ring with a radius of 7 ~ 10cm and a spatial distribution of one Closed ring. In the ion cyclotron resonance heating experiment, we use a frequency of 4.81MHz, a power of 40kW RF source, ECR plasma ion cyclotron resonance heating, ion and electron were observed to varying degrees of heating, the ion temperature from the original average 3eV rose to 8eV, the electron temperature rose from the average of 20eV to 30eV, and the plasma potential and plasma confinement characteristics have changed.
