Abstract: The present disclosure provides an ion detector for improving the effect of electric field for pulling in an ion to be detected to a first-stage electrode of a secondary electron multiplier (SEM), and improving the effect of a stray light reduction. In one example embodiment, an ion detector includes a SEM, and a lead-in electrode for pulling in an ion to a first-stage electrode side of the SEM. At least one of the area of the lead-in electrode and a potential difference between the lead-in electrode and neighboring electrodes of the lead-in electrode, the neighboring electrode being an electrode not of the SEM, is set so that the light amount of internal-stray light generated inside the detector entering the first-stage electrode is not more than that of external-stray light generated outside the detector entering the first-stage electrode, when an ion is introduced into the detector.

Abstract: An image intensifier and electron multiplier therefor is disclosed. Photons of an image impinge a photo-cathode that converts the photons to electrons. An electron multiplier multiplies the electrons from the photo-cathode to create an increased number of electrons. A sensor captures the increased number of electrons to produce an intensified image. The electron multiplier is an electron bombarded device (EBD) containing a semiconductor structure. The semiconductor structure has an input surface for receiving electrons and an emission surface for passing an increased number of electrons. The semiconductor structure is doped to direct the flow of electrons through the semiconductor structure to an emission area on the emission surface.

Abstract: A photomultiplier which can be easily made compact has a dynode unit constituted by stacking a plurality of stages of dynode plates in an electron incident direction in a vacuum container constituted by a housing and a base member integrally formed with the housing. Each dynode plate has an engaging member engaged with a connecting pin for applying a voltage at a side surface thereof. Through holes for guiding the connecting pins from the outside of the container are formed in the base member. Each engaging member is arranged not to overlap the remaining engaging members in the stacking direction of the dynode plates. The arrangement position of each engaging member and the arrangement position of the through hole for guiding the corresponding connecting pin to be connected are matched with each other.

Abstract: An evacuated tube has a face plate and a tubular body with at least a portion of the body having a circular cross section. In the evacuated tube is an electron emissive electrode adapted to release electrons in response to impinging photons or photoelectrons, means for collecting the electrons and an anode. The electron emissive electrode is cup shaped, having an approximate circular top opening through which photons or photoelectrons enter to impinge on the electrode, a circular rim around the periphery of the top opening, and a side opening through which the electrons pass to exit from the electrode. The inside of the electrode is lined with electron emissive material. The electrode is positioned in the portion of the tubular body having the circular cross section with the rim of the electrode substantially parallel to the plane of the circular cross section and having a diameter substantially the same as the diameter of the circular cross section, and with the top opening of the electrode facing the face plate. The means for collecting the electrons is positioned laterally adjacent to the electrode between the side opening and the tubular body.

Abstract: This disclosure depicts cathodo-luminescent devices and luminescent panels employing X-Y matrices of such devices as the display elements. The cathodo-luminescent devices are depicted as each comprising a two-section cell containing an ionizable gas at very low pressure. The first section comprises an electronmultiplier serving as a controllable source of free electrons. Free electrons are drawn from the electron-multiplier and accelerated in the second section to high energies whereupon they collide with a light-emissive phosphor screen. Other structures including means for modulating the flow of electrons to the screen are disclosed.

Abstract: An electrode includes an electron or irradiation transmissive conducting layer and an electron-emissive layer of insulating material in spongy form. This layer may be of BaF2, LiF2, MgF2, MgO, Al2O2, CsI, KCl or NaCl and preferably has a density of only about 1% of the same material in bulk form, e.g. 0.01 to 0.1 gms. per cc. with a thickness of 10 to 100 m . The layer may be formed by deposition in a gaseous atmosphere, e.g. argon at 1 to 2 mm. of Hg pressure, with a spacing of about 3 inches between the evaporator and the receiver, which may be rotating. Alternatively magnesium may be burnt in air at atmospheric pressure about 14 inches from the receiver. The receiver may be an aluminium film supported by a metal ring and formed by vacuum deposition of aluminium on to a film of thermally removable cellulose nitrate to a thickness of 140 to 1000 . Specifications 792,507, 862,211 and 898,433 are referred to.
