Abstract: An ionization gauge and controller therefor where the gauge has a sensitivity which is reproducible gauge to gauge and stable over time in the same gauge. An ionization gauge with a very much lower and a somewhat higher pressure limit than prior art gauges is also disclosed. Elements are also described for launching all electrons in a tight beam in Bayard-Alpert type geometry, so that all the conditions for reproducible and stable sensitivity are satisfied. Elements are also described for collecting all electrons at low energy so that soft X-ray production is negligible.

Abstract: An improved Bayard-Alpert type vacuum ionization tube includes an electron collecting grid surrounding and coaxial with a centrally located positive ion collector. The grid has an inner diameter of approximately 0.5 inches and an electron emitting filament is positioned outside of the grid and spaced from the grid by approximately 0.2 inches. A grounded shield screen surrounds the grid outside of the filament and is coaxial with the collector. The tube has constant vacuum gauging sensitivity over the range from 10 1 to 5 X 10 10 torr.

Abstract: A magnetron ionization gauge having the capability of measuring ultrahigh vacuum of the order of 2 X 10 16 torr with high sensitivity and conversion constant is formed with a hollow cylindrical anode and an electron-containment ferromagnetic plate at either end of the anode. An ion-collector is centrally located within a cylindrical anode and extends the entire length thereof. An electron-emitting cathode is located off center between the ion-collector and the anode wall and parallel to the longitudinal axis. An ion-collector shield extends the entire length of the ion-collector and is interposed between the ion-collector and the electron-emitting filament. The device is biased well beyond cutoff to provide restricted curvilinear paths for ionizing the electrons circulating around inside the anode.
