Abstract
909,640. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 30, 1959 [Aug. 2, 1958 ; April 3, 1959], No. 26192/59. Class 39 (1). In an ion getter pump the anode is substantially ring shaped and cathode parts are disposed at both sides of the anode plane and a magnetic field is arranged so that certain lines of force connecting the two cathode parts do not intersect the anode surface; in operation at least one cathode part is incandescent and is provided with a stock of evaporable getter material which condenses on the walls of the apparatus, thus forming a collecting surface for ions liberated during a discharge between the anode and cathode. In one form, Fig. 1, a molybdenum ring anode 2 has two titanium coils on opposite sides thereof (cathodes) and a contact spring 5 for the titanium wall coating which is held at cathode or at a more negative voltage. One of the cathodes is heated by D.C. or A.C. 10 is a permanent magnet and the device may be connected to a cathode-ray tube, Fig. 3 (not shown). In another embodiment, Fig. 4, the cathodes are three V-shaped tungsten parts 12 spun with barium-nickel sheath wire and two V-shaped tungsten parts 13 spun with titanium sheath wire, one at least of the cathodes being heated; a further barium getter 14 is provided. In another embodiment, Fig. 5 (not shown), the anode is two rings of barium getter. In another embodiment, Fig. 6 (not shown), the hot cathode is three V-shaped tungsten wires spun with titanium wire. A cold cathode plate of titanium is vaporized along with the titanium wire of the hot cathode. The anode is a thick band of titanium and may also partly evaporate in operation.
