热电子在ECR(Electron Cyclotron Resonance)源中有着非常重要的作用
为了研究ECR源的工作参数(微波功率、磁场等)对热电子的影响
我们对SECRAL(Superconducting ECR ion source with Advanced design in Lanzhou)等离子体在轴向发出的轫致辐射谱进行了系统的测量。从测得的轫致辐射谱中我们得到用来衡量热电子能量的参考量——光谱温度Tspe
并且对ECR源的几个工作参数与Tspe的关系进行了讨论。
Hot electron is a key issue for ECR ion sources. In order to study the dependence of hot electrons on external parameters of the ECR ion source
such as the RF power and the magnetic confinement configuration
bremsstrahlung spectra emitted by the SECRAL plasma axially were measured systematically. The spectral temperature Tspe
the index of hot electron energy
was obtained from the spectra
and influences of the source parameters on the Tspe were discussed.
