Fast electron-emission phenomenon from Grimm glow-discharge plasmas and its application to X-ray elemental analysis

研究成果: Article査読

抄録

A maximum high voltage of 5 kV was applied to a Grimm glow-discharge lamp using helium gas. The characteristic X-rays and continuous X-rays were measured from an X-ray window attached to the lamp, indicating the existence of fast electrons which could excite X-rays. The electrons emitted from the cathode surface by ion impact are accelerated by the cathode fall region, then pass right through both the negative glow and the hollow anode, resulting in bombardment to the X-ray window. The fast electrons were utilized as an excitation source in X-ray elemental analysis. It was demonstrated that quantitative analyses of Fe-Si alloys are possible by this electron-excited X-ray emission method.
