Abstract
1,049,125. Ion pumps. CANADIAN PATENTS & DEVELOPMENT Ltd. July 30, 1963 [Aug. 23, 1962], No. 30183/63. Heading H1D. A magnetron-type cold-cathode getter-ion pump is similar in construction to the sputterion pump described in Specification 1,049,124, but has an evaporator 20 and accelerator electrodes 23, on which evaporated material is deposited, in place of a sputter cathode. The envelope of the pump is formed by upper and lower polepieces 7, 8, a wall 13 of stainless steel or other non-magnetic material, a glassto-metal seal 6, and a tubular member 11 for connection to a tubulation of a system to be evacuated. Rings 9 of sheet titanium form a cathode with metal sheets 10, preferably of titanium, covering the faces of the polepieces 7, 8. A cylindrical anode 12 is supported by a rod 15. An evaporator 20 having a heating winding 21 is supported by leads 5 passing through the seal 6. Accelerator electrodes 23 are supported by rods 24 passing through the seal 6. A number of permanent magnets 14 contact the polepieces 7 and 8 which are preferably of mild steel. Three assemblies as shown may be superimposed (Fig. 4, not shown) to provide a pump capable of increased pumping speeds.
