摘要

我们报道了一种新的比较方法的发展，用于估计重元素等离子体和高温铁激光产生的等离子体的电子温度。为此，研究了两种激光产生的等离子体——镁等离子体和铁等离子体——在目标上相同的激光辐射通量下。等离子体诊断使用x射线光谱的H-和he -样Mg离子。记录了Fe离子在波长15 ~ 150 Å范围内的VUV光谱，研究了100 ~ 400 eV范围内Fe离子VUV光谱结构随te的变化规律。这些数据对于诊断含有铁元素的等离子体源是必要的。

Spectroscopic VUV diagnostics of high-temperature iron plasmas using the comparison method

We report the development of a new comparison method used to estimate the electron temperature T e of heavy-element plasmas and high-temperature iron laser-produced plasmas. To this end, two laser-produced plasmas – magnesium plasmas and iron plasmas – were studied at identical laser radiation fluxes on the target. Plasma diagnostics was performed using X-ray spectra of H- and He-like Mg ions. VUV spectra of Fe ions were recorded in the wavelength range 15 – 150 Å As a result, the change in the structure of the VUV spectra of Fe ions as a function of T e in the range of 100 – 400 eV was studied. These data are necessary for diagnosing plasma sources containing the iron element.
