高频离子源等离子体的光谱诊断
Spectroscopic diagnosis of RF ion source plasma
摘要
采用发射光谱法研究了高频离子源的等离子体性质.该离子源应用于ZF-200keV中子发生器中,是一种电感耦合型无极环形放电高频离子源.实验采用绝对定标后的光学多道分析系统测定了离子源等离子体在不同阶段氢原子巴耳末谱线系中前三条谱线的强度,并采用部分局部热力学平衡状态的理论,计算出了相应阶段高频离子源等离子体的电子温度、氢原子浓度、氢离子浓度等参数,并进行了简要分析.
Abstract
Plasma characteristics of an RF ion source were investigated by emission spectroscopy. The RF ion source, applied in ZF200keV neutron generator, is an orbicular discharge RF ion source coupled with inductance. The spectral line intensities of the first three atomic lines in hydrogen Balmer series in different moment of RF ion source plasma, were measured with calibrated optical multichannel analyzer. Some plasma parameters in relevant time, including electron temperature, hydrogen atom density and hydrogen ion density, were calculated and analyzed using partial local thermodynamic equilibrium theory.
