Study of electrodeless discharge lamp properties and plasma/wall interaction

摘要

Our work is concerned with the preparation and investigation of high-frequency light sources, containing different elements, excited by means of outer electrodes, so called, electrodeless light sources. In this work we consider our experience in the technology of the electrodeless light sources, on the example of mercury and rare gases. The interaction process with the discharge vessel is investigated using spectroscopic emission measurements of the filling elements and the wall surface diagnostics by means of the atomic force microscope. The necessary quantity of the mercury filling is estimated to reach a considerably long working life.
