Abstract:

The report covers work done to improve the performance of a mass spectrograph in the semi-quantitative analysis of solids. Reproducibility and accuracy were found to be limited by many instrumental factors, as well as sample inhomogeneity. A broad-based evaluation of highest-purity materials, to be used as compacting powders or counterelectrodes, has led to at least one source which can supply gold of adequate purity. The design and construction of a short-pulse ion source was finished which is of particular value in surface studies. Ionsensitive thin-film plates were developed which show marked improvements in line sharpness, halation, signal-to-noise ratio, and vacuum characteristics. Author
