Abstract
The proposed research project is focused to the studies of the diffusion of gasses in materials used in vacuum technology (Hydrogen in stainless steels, helium in different glasses) and the phenomena of adsorption and desorption of different gasses at room temperature on technical surfaces of stainless steels, which are used as construction material for vacuum chambers.
The proposed studies are aimed to support the development of the primary static expansion system for the generation of low pressures. This system is currently being built in the Laboratory of Pressure Metrology at the Institute of Metals and Technology in Ljubljana and it is foreseen that this system will serve as Slovenian national standard in the range of medium and high vacuum.
The characterisation of the static expansion system requires extensive studies of hydrogen diffusion and outgassing from the chamber walls and the studies of adsorption and desorption of different active gasses which may be used for calibrations in the system. Special attention will be paid to the adsorption of atmospheric gasses and moisture during the venting period of the system whenever the system is opened to the atmosphere during the exchange of vacuum gauges for calibration.
The research will also include the experimental studies and numerical modelling of the diffusion of helium at room temperature in different glasses: quartz, prex and kovar.
