    Abstract: The present invention addresses the problem of providing a device with which it is possible to adjust the focal point of an electron beam both toward a shorter focal point and toward a longer focal point after an electronic gun was fitted on a counterpart device.
    The aforementioned problem can be solved by an electron gun including a photocathode, and an anode, the electron gun furthermore comprising an intermediate electrode disposed between the photocathode and the anode, the intermediate electrode comprising an electron-beam passage hole through which an electron beam released from the photocathode passes, and the electron-beam passage hole having formed therein a drift space in which, when an electrical field is formed between the photocathode and the anode due to application of a voltage, the effect of the electrical field can be disregarded.

    Abstract: A system and method for producing a continuous or pulsed source of high energy electrons at or near atmospheric pressure is disclosed. High energy electrons are used to ionize analyte molecules in ambient air through collisions with reactant ions. The device includes an electron emitter, electron optics, and a thin membrane in an evacuated tube. The electron emitter may include a photocathode surface mounted on an optically transparent window and an external source of UV photons. The transparent window may include a UV transparent window mounted on an evacuated tube and/or the evacuated tube may be a transparent tube on which a photocathode surface film is deposited. The electron optics may include successive electrodes biased at increasing voltages. The membrane may include a material transparent or semi-transparent to energetic electrons. Upon impacting the membrane, continuous or pulsed electron packets are partially transmitted through to a high pressure ionization region.

    Abstract: A fast switching device employing at least two semiconductor p-n junction devices in a back-to-back arrangement with the voltage which is to be switched applied across the semiconductor devices. If the output is to be a replica of the switched voltage, the latter is also applied to control an electron beam which irradiates one or both semiconductor devices when the switch is to be closed. A square-wave output can be produced by utilizing an electron beam which is not proportional to the switched voltage but is simply turned on and off in synchronism with it and has a constant value when it is on.

    Abstract: An electron beam head for reproducing magnetically recorded video signals wherein magnetic fields from the record medium are channeled to the interior of the envelope to deflect the primary electrons transversely to the scanning direction of the beam. In one embodiment, the sensing electrodes are at opposite sides of the magnetic field region at an end wall of the envelope, while in another embodiment the primary electron beam passes through the openings in a grid of magnetic wires so as to interact with the magnetic fields therebetween, electrostatic deflecting means serving to deflect the electron beam through a substantial angle as it leaves the grid so as to impinge on sensing electrodes remote from the grid. In a third embodiment, secondary electrons are conducted into a branch tube extending from the main envelope and a single electrode senses the degree of deflection of the secondary electrons by the magnetic fields permeating the secondary emission region.
