| 简介 |
The ion source has an ionisation chamber and a UV/VUV-excimer light source for generating ions by directing light into a sample gas. The light source is provided by a deuterium lamp, a micro hollow cathode lamp, a micro point lamp, a DC discharge lamp, a barrier discharge lamp, or an electron beam UV/VUV lamp, with an electron gun (1), a membrane (3) between the electron gun and a gas space (9) containing a rare earth gas or gas mixture and optical elements (11, 12) for imaging the light emission volume into the ionisation space (14). |
