最近对 MAP-II 激光汤姆逊散射 (LTS) 系统的升级以及新型异质串联双单色仪的开发,使得可检测的电子温度低至 0.05eV,电子密度低至 1012cm-3。这使得能够研究 He 电子离子复合 (EIR) 等离子体,并与部分局域热平衡 (p-LTE) 中 He I 里德堡态的光学发射光谱进行比较。具有主量子数 n=9–16 跃迁的 21P-n1D 和 23P-n3D 系列用于 Tederivation。玻尔兹曼图和碰撞辐射模型拟合的结果与 LTS 的结果一致。 0.06eV 的极低温度(通常通过 He EIR 态的玻尔兹曼图获得)得到证实。
The recent upgrades of the MAP-II Laser Thomson Scattering (LTS) system and the development of a new Hetero-Tandem Double Monochromator, allowed detectable electron temperatures as low as 0.05eV and electron densities as low as 1012cm-3. This enabled the study of He Electron Ion Recombining (EIR) plasmas and the comparison with optical emission spectroscopy for He I Rydberg states in partial local thermal equilibrium (p-LTE). 21P-n1D and 23P-n3D series with transitions from principal quantum numbers n=9–16 were used for the Tederivation. Results from both Boltzmann plot and Collisional Radiative model fitting are consistent with those from LTS. The very low temperature of 0.06eV, usually obtained by the Boltzmann plot for He EIR states, is confirmed.
