Elucidation and control of the low temperature recombining plasmas under fusion relevant conditions are crucial issues. In this study, we applied a conditional average for laser Thomson scattering technique to measure the temporal evolution of the plasma instability in detached recombining plasmas in the divertor simulator NAGDIS-II. In recombining plasmas, it is shown that the electron energy distribution function has a non-Maxwellian component, and the fraction of the low electron temperature component increases with the gas pressure. It is found that one of the major reasons to cause the non-Maxwellian distribution function is in the temporal variations of the electron temperature. By using the conditional averaging method, the temporal evolutions of the spatial (vertical and radial) profiles of the electron density and temperature are revealed for different frequency ranges.

通过激光汤姆森散射对分离等离子体的重组进行时空测量

在聚变相关条件下阐明和控制低温复合等离子体是至关重要的问题。在这项研究中,我们对激光汤姆森散射技术应用了条件平均值,以测量偏滤器模拟器 NAGDIS-II 中分离的重组等离子体中等离子体不稳定性的时间演变。在复合等离子体中,表明电子能量分布函数具有非麦克斯韦分量,并且低电子温度分量的分数随着气压的增加而增加。发现导致非麦克斯韦分布函数的主要原因之一是电子温度的时间变化。通过使用条件平均法,
