本研究的目的是研究高密度低温复合氢等离子体中负氢离子的密度。在螺旋波激发的小型分流器模拟器中获得了复合氢等离子体。复合等离子体的电子密度和电子温度分别为（1 ~ 4）× 1012 cm−3和0.1 ~ 0.2 eV，分别由氢原子激发态的居群分布和Saha-Boltzmann方程计算得到。在重组等离子体中，负离子与电子密度的比值在0 ~ 0.02之间，比电子密度为1011 cm−3的等离子体低一个数量级。负氢离子的低效率产生可能归因于高密度等离子体中氢分子的显著解离。
The objective of this work is to investigate the density of negative hydrogen ions in high-density, low-temperature recombining hydrogen plasmas. The recombining hydrogen plasmas were obtained in a compact divertor simulator excited by helicon-wave discharges. The electron density and the electron temperature of the recombining plasmas were (1–4) × 1012 cm−3 and 0.1–0.2 eV, respectively, which were evaluated by comparing the population distribution of the excited states of atomic hydrogen with the Saha–Boltzmann equation. The ratio of the negative ion to electron density ranged between 0 and 0.02 in the recombining plasmas, which was one order of magnitude lower than that observed in a plasma with an electron density on the order of 1011 cm−3. The less efficient production of negative hydrogen ions may be attributed to significant dissociation of molecular hydrogen in high-density plasmas.
