摘要

为了诊断Z箍缩等离子体电子温度，研究了氩的双电子伴线与类氦共振线的强度比和等离子体电子温度的关系。利用椭圆弯曲晶体谱仪在“阳”加速器上探测X射线光谱，采用X射线胶片接收信号。谱仪获取了氩的类氦谱线及类锂伴线，计算了伴线k与共振线w的强度比以及伴线j与禁戒谱线z之和与共振线强度比，利用伴线与共振线强度比值和等离子体电子温度的关系诊断出电子温度为960～1060keV，实验结果证明谱线强度比值法是一种探测电子温度很有效的诊断方法。

Abstract

The line ratios between dielectronic recombination satellites and the w-resonance are analyzed as a function of plasma temperature for temperature diagnostics. The n=2—1 spectral emission pattern of heliumlike argon

together with the associated satellite emission originating from lithiumlike argon have been measured with x-ray elliptical curved crystal spectrometer on Yang accelerator. Experimental results using curved Mica crystal analyzer are described and show spectrum of argon-puff Z-pinch plasma. Spectra showing the He-like resonance line w and the satellites j

the magnetic quadrupole M2 line

the intercombination line y

the forbidden line z and a cold Kα line of argon were recorded with X-ray film. The line ratios between dielectronic recombination satellites ( j+z

k) and the w-resonance line were found and a good agreement between the theoretical models and the experimental results

supporting the method of line-ratio measurement as a temperature diagnostic for plasmas.
