    Abstract: An S-20 response multialkali photocathode is produced by exposing a layer of antimony to activating vapors of potassium, sodium, and cesium. In one method the antimony layer is exposed to cesium at a temperature of about 240*C. prior to exposure to potassium or sodium, and the exposing to cesium is terminated before the photosensitivity reaches a peak. In another method, the antimony layer is exposed to cesium at a temperature of about 240*C. subsequent to exposure to potassium and sodium, and the exposing to cesium is terminated when the photosensitivity reaches a peak.

    Abstract: A method of making a structure for use in a black and white or color Kinescope or the like, the structure being called a multichannel array and including a perforated channel type electron multiplier with two perpendicular sets of insulated conductive strips extending over rows and columns of the multiplier holes. The strips have holes in registration with the multiplier holes. Conductive strips and glass insulating layers are deposited using a photoresist layer with or without a transparent photographic film. The photoresist is exposed to light through the multiplier holes.

    Abstract: A method comprising coating an uncontaminated emitter surface of an emitter body with a non-contaminating protective layer and then mounting the body so that the coated surface is in the interior of an envelope. The envelope and body are then heated to a first temperature to drive contaminant gases from surfaces of the envelope interior while these gases are simultaneously pumped out. The first temperature is low enough that the protective layer remains. Then the body is heated to a second temperature, higher than the first, and the protective layer evaporated off the surface while the envelope is maintained at a temperature below the first temperature. Thereafter the emitter surface is activated by the application thereto of a material which lowers the work function.

    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.
