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.
