【摘要】 本文敍述了我们新近建造的一台高电压、大电容、低电感三电极真空火花光源。用此光源与SGV-50真空紫外光谱仪相配合,分别用C、Al、Ti等元素作电极,进行了积分光谱的初步观测。在200A—2000A的波段区,辩认出高离化态谱线330条,其中C谱线174条,O谱线68条,N谱线44条,Al谱线24条,Ti谱线20条。实验表明,这种光源使用效果比较好。更多还原

【Abstract】 A low inductance three-electrode vacuum spark source for generating spectra of highly ionized atoms fed by a 30-kv, 1.43-μF capacitor has been constructed and in operation for some time. The source was used to produce the radiation, which was analyzed in a vacuum ultraviolet spectr-ophotometer (SGV-50) with a concave grating set for normal incidence. By use of spark between electrodes made of materials containing elements under investigation, we have recorded lines of multiply ionized C, Al and Ti in the region 200-2000A. Majority (174 in number) of the emission lines of carbon, sixty-eight lines of oxygen, forty-four lines of nitrogen, twenty-four lines of aluminium and twenty lines of titanium have been identified.更多还原
