    Abstract: An ionization gauge for isolating an electron source from gas molecules includes the electron source for generating electrons, a collector electrode for collecting ions formed by the impact between the electrons and gas molecules, and an electron window which isolates the electron source from the gas molecules. The ionization gauge can have an anode which defines an anode volume and decelerates and retains the electrons in a region of the anode. The ionization gauge can have a plurality of electron sources and/or collector electrodes. The collector electrode(s) are be located within the anode volume. The ionization gauge can be a Bayard-Alpert type that measures pressure.

    Abstract: A triode ionization gauge controller employing logarithmic amplifiers develops a signal proportional to the logarithm of the ratio of an ion current to the ionizing current. Gaseous thermal conductivity is employed to reduce emission current at high pressure, thereby prolonging the life of the cathode. Complete over-pressure protection is accomplished by comparing emission current with respect to a predetermined limiting current.

    Abstract: An ionization pressure gauge tube is designed as a triode including an electron-emitting hot cathode, an electronaccelerating electrode and an ion collector arranged between the cathode and the accelerating electrode. The cathode, accelerating electrode and collector have dimensions and a relative arrangement such that the triode system has a transconductance of 0.25 to 1.00. The accelerating electrode is designed as a cylinder and the ion collector is designed as a system of 3 to 5 rods extending parallel to the axis of the tube and arranged symmetrically around the cathode. The cylindrical accelerating electrode has a diameter of from 8 to 16 mm.

    Abstract: An apparatus for generating an electrostatic space charge in a rotation-symmetrical magnetic field, in which an electron beam from an electron gun which is arranged laterally on the field space generates the space charge in the field space. The electron beam may be adjusted by mechanical adjustment of the gun and also by means of the potential of a conducting sleeve in the magnetic field. By means of this potential, it is also possible to adjust the ratio between the contributions to the space charge which are due to primary electrons and to secondary electrons produced by the primary electrons in a residual gas in the field space.
