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: In a laminated channel plate electron multiplier, an apertured metal sheet (32) is disposed at a small distance (30 .mu.m) from the outer surface of the input dynode and is used to provide a small negative field for turning back stray secondary electrons which have sufficient energy to follow trajectories across the input side of the input dynode. More particularly, the areas between the apertures of the input dynode (22) are masked by a material (34) having a secondary electron emission coefficient of less than 2, which material (34) is provided on the outer surface of the apertured metal sheet (32), the metal sheet (32) being spaced from the input dynode (22) by an insulating material (36). A potential of the order of -10 V relative to the input dynode is applied to the apertured metal sheet (32).

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: An electron multiplier includes a plurality of staggered parallel dynodes. The dynodes include spaced confinement bumps along their lengths with active areas between the bumps. The confinement bumps and active areas therebetween define a plurality of channels which extend from a cathode at one end of the multiplier. Each channel traverses the staggered parallel dynodes and causes an electron beam to pass therethrough without spreading. The multiplier is useful in a display device which includes a plurality of line sources of electrons, e.g., a plurality of cathode stripes.

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.
