“…In the lamp used here, excimer molecules are formed via electron beam excitation of a dense gas . By choosing various rare gases or gas mixtures, different wavelengths can be generated. ,− The main innovation of the light source is a 0.7 × 0.7 mm 2 , 300-nm-thick SiN x foil, which separates the rare gas volume ( p > 1 bar) from the vacuum chamber containing an electron gun (EG). The EG generates a 13−15-keV electron beam, which is directed into the rare gas through the SiN x foil with low energy loss.…”

Single-photon ionization (SPI) using vacuum ultraviolet (VUV) light produced by an electron beam pumped rare gas excimer source has been coupled to a compact and mobile time-of-flight mass spectrometer (TOFMS). The novel device enables real-time on-line monitoring of organic trace substances in complex gaseous matrixes down to the ppb range. The pulsed VUV radiation of the light source is employed for SPI in the ion source of the TOFMS. Ion extraction is also carried out in a pulsed mode with a short time delay with respect to ionization. The experimental setup of the interface VUV light source/time-of-flight mass spectrometer is described, and the novel SPI-TOFMS system is characterized by means of standard calibration gases. Limits of detection down to 50 ppb for aliphatic and aromatic hydrocarbons were achieved. First on-line applications comprised real-time measurements of aromatic and aliphatic trace compounds in mainstream cigarette smoke, which represents a highly dynamic fluctuating gaseous matrix. Time resolution was sufficient to monitor the smoking process on a puff-by-puff resolved basis. Furthermore, human breath analysis has been carried out to detect differences in the breath of a smoker and a nonsmoker, respectively. Several well-known biomarkers for smoke could be identified in the smoker's breath. The possibility for even shorter measurement times while maintaining the achieved sensitivity makes this new device a promising tool for on-line analysis of organic trace compounds in process gases or biological systems.

The spectral and energy characteristics of a compact krypton glow-discharge lamp used as the ionization source in analytical devices have been investigated. The emission spectrum of the lamp in the 115-200 nm VUV region has been studied, the flux of VUV emission has been measured, and data concerning the intensity ratio of the 116.49 and 123.58 nm resonance lines of krypton emitted by the lamp have been obtained.

“…A mixture of argon and nitrogen shows an enhanced emission on the C-B band of nitrogen between 300 and 400 nm. Mixtures of rare gases show energy transfer from the light to the heavier rare gas with emission due to the formation of mixed molecules [11] and for higher concentrations of the heavier species on the rare gas excimer band of these heavier species (first and second continuum) [12].…”

Abstract. Electron beams with a particle energy of typically 12 keV are used for collisional excitation of dense gases. The electrons are sent through ceramic membranes of only 300 nm thickness into gas targets. Excimer light emission from the pure rare gases and from gas mixtures are studied for the development of brilliant VUV and UV light sources. The application of the technology for gas kinetic studies is described and its potential for building very small electron beam pumped lasers is discussed.
