Revalde1, , ,1 Institute of Atomic Physics and Spectroscopy, Univerisity of Latvia, Skunu 4, Riga, LV1050, Latvia2 Institute of Theoretical and Applied Mechanics, Novosibirsk, RussiaOur work is concerned with the preparation and investigation of highfrequency 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.1. GeneralThe history and development of lamps has always been closely connected to materials properties used for them. The properties of materials have always determined new steps towards more efficient light sources. The trend in modern light source development clearly points towards a miniaturization with the effect of higher radiation intensity from the lamp, also bined with demands of higher lifetime. New aggressive fillings are introduced and the thermal loading can reach the temperature limits of the wall material. The large diversity of lamp applications requires specific properties of the used envelope material and in practice it has caused some problems: wall corrosion and blackening, layer formation, solarisation and UV radiation resistance, increasing ignition voltage, luminescence, outdiffusion of filling ponents, microcracks under VUV –radiation [1]. In this work we deal with the study of filling problems as well as spectroscopic properties of electrodeless discharge lamps for broad range of applications.Electrodeless lamps, driven with the high,radio or microwave frequencies, have nowadays many nonlighting applications, but they start to penetrate also general lighting markets. Light sources, based on highfrequency or radiofrequency electrodeless discharge are widely used for atomic absorption analysis,magnetometry, etc. Our research is concerned with the preparation and diagnostics of new performance high frequency electrodeless light sources (HFEDLs), filled with different elements for their use in scientific devices [2].The history of development of highfrequency (HF) electrodeless light sources (EDL) in science and technique goes back to the twenties. Jackson began to use the HF discharge, which was excited in a tube, filled with rubidium, by means of electrodes placed outside the tube. The rubidium pressure was mbar, and the source was heated to increase the line intensities [3]. A similar design was used by different research groups until the beginning of fifties to excite the spectra of various elements [4, 5]. One of the first HF light sources as often used today was created by Bell and Bloom in 1961 [6].The HF EDS vessels are mostly made of glass or quartz and filled with a working element and buffer gas (usually rare gas). Lamp contains lamp balloon and a short side branch (cold spot) containing working element. The lamp vessel is placed in highfrequency generator coil to induce an inductivecoupled electrodeless discharge. Typically, the HFelectromagnetic is applied. The side branch could be thermostated to control the metal vapour pressure in the lamp. The light source vessel is placed into some thermo isolation. In general, the lamps could be designed in different forms.Such light sources have many advantages than many others due to the absence of the electrodes and hence they are easier to manufacture and to create plasma describing models. Many problems which are caused by electrodes, in these lamps are eliminated. In these lamps the optimal amount of filling has to be found experimentally for each element [7, 8]. However, during the lamp operation time, interaction of the filling element with the walls of the vessel occurs. This process depends strongly on the light source operating conditions and on the filling type.2. ExperimentaIn order to find out the optimum and to study the plasma interaction with a wall, we have prepared HF EDL samples from quartz with a spherical form of 20 mm diameter with mercury in a metal phase of different amount. The inductive coupled discharge was induced in the light
