Abstract:

Progress is reported on effort aimed at achieving a higher degree of reliability in electron tubes through a better understanding of the kinds and quantities of gases which occur in these tubes. Amperex tube type 5894 is the subject of the initial phase of the study because it is a high quality tube of relative simplicity. A high quality tube whose manufacture is in good control should exhibit similar outgassing from sample to sample. A bakeable, ultra-clean, ultra-high vacuum system for these experiments is nearing completion. It will incorporate an omegatron mass spectrometer for the purpose of analyzing evolved gases, and a novel system of orifices and pressure gauges which will permit the determination of the quantities of each of various gas types. Pure gases of known types will be injected into the system at known rates for an initial calibration a simplified version of the same procedure can be used at any later time for a quick check of the over-all system performance. To insure data reliability, the apparatus is so designed that each experiment will yield two sets of data from which two separate calculations of the final results can be made. A detailed description is presented of the systems operation as well as its construction. Author
