在S—300装置上研究了丝阵靶Z箍缩等离子体的软X射线辐射的动态过程。利用多通道X射线谱仪在50～2000eV范围内测量了丝阵靶内爆等离子体X射线辐射谱,辐射主要位于60～220eV谱段。辐射谱可用温度为40～50eV的Planck黑体谱近似描述。在能量高于500eV的谱段,辐射谱与Planck黑体谱有较大的偏离。这主要是因为等离子体热斑的出现、在1.5～2keV范围内线谱的存在和加速电子轫致辐射的结果。
The dynamic process of soft X-ray radiation of a Z-pinch plasma with a filament array was studied at S-300. The multi-channel X-ray spectrometer was used to measure the X-ray emission spectrum of the implosion plasma of the filament array in the range of 50-2000 eV. The radiation mainly lies in the spectrum of 60-220 eV. The radiation spectrum can be approximated by the Planck blackbody spectrum at a temperature of 40-50 eV. At energy bands above 500 eV, there is a large deviation between the radiation spectrum and the Planck blackbody spectrum. This is mainly due to the presence of plasma hot spot, the presence of line spectra in the range of 1.5-2 keV and the result of accelerated electron Bremsstrahlung.
