高光谱分辨率X射线成像晶体光谱仪已在J-TEXT托卡马克装置上实现了类氦Kα谱及其卫星谱线的测量。类氦氩的 Kα 光谱的波长范围为 3.9494 Å 至 3.9944 Å，其中包括共振线 w、互组合线 xandy、禁线 z 和许多卫星线，使用标准加布里埃尔表示法引用。在低密度放电中，非热电子可以显着增强q、r卫星线和z线的强度。由于等离子体密度低，会产生非热电子。来自 NaI 探测器的高硬 X 射线通量和高能失控电子的显着下移电子回旋加速器发射也表明低密度放电中存在大量失控电子。电子的非热部分可以影响激发/跃迁平衡或电离/复合平衡。 Theqline主要由类锂氩内壳激发产生，therline部分由类锂氩内壳激发和类氦氩双电子复合产生。
A high spectra resolution X-ray imaging crystal spectrometer has been implemented on J-TEXT Tokamak for the measurements ofKαspectra of helium-like argon and its satellite lines. The wavelength range ofKαspectra of helium-like argon is from 3.9494 Å to 3.9944 Å that includes the resonance line w, intercombination linesxandy, forbidden linezand numerous satellite lines, referenced using standard Gabriel notation. In low-density discharge, the intensity ofq,rsatellite lines andzlines can be significantly enhanced by non-thermal electrons. Non-thermal electrons are produced due to the low plasma density. The high hard X-ray flux from NaI detector and significant downshift electron cyclotron emissions from energetic runaway electrons also indicated that there is a large population of runaway electrons in the low-density discharge. The non-thermal part of electrons can affect the excitation/transition equilibrium or ionization/recombination equilibrium. Theqline is mainly produced by inner-shell excitation of lithium-like argon, and therline is partially produced by inner-shell excitation of lithium-like argon and dielectronic recombination of helium-like argon.
