The importance of light generation in the vacuum ultraviolet spectral range increases constantly in industry as well as research and development. elux uses a novel concept. Pure rare gases and rare gas mixtures at elevated pressures are excited by low energy electron beams to generate vacuum ultraviolet (VUV) radiation.

Electrons penetrating a thin, but stable and inert membrane are stopped within the gas on a very short distance creating a small, brilliant, VUV-light emitting plasma. The light source remains cold due to the extremely high photon yield of this process. A short distance from the plasma to the exit window allows a large accessible emission angle. Light emission follows directly the fast and easy to modulate electron beam without ignition or termination problems. A computer-controlled power supply allows for internal or external pulsing as well as stabilized and completely continuous wave operation.

Successful application of this light source and excitation technique has been widely demonstrated in single-photon-ionization (SPI) mass spectroscopy as well as fundamental research such as gas-kinetic studies and lifetime measurement of excited species or material science.
