Abstract:

The removal of hydrogen, considered as an impurity gas, from a closed noble gas helium discharge system is studied using the techniques of 1 hydrogen pumping through a heated palladium membrane and 2 hydrogen gettering by a titanium film deposited on a water-cooled stainless-steel surface. Mass spectrometric and optical measurements are presented which show the effect of helium background on hydrogen removal rate. Experimental results of hydrogen gettering on titanium agree with theoretical calculations based on kinetic theory, and not only support, but extend earlier work of other investigators. Removal of hydrogen by the palladium membrane is about equally effective for the geometry employed. In addition, laser transmission measurements of deposition of titanium films on a glass surface are studied. Dependence of deposition rate and film thickness on helium background pressure, and source temperature are shown. Author
