Abstract

778,434. Heavy-ion-beam tubes; electrode materials. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 24, 1955 [May 25, 1954], No. 14946/55. Class 39(1). An ion source comprises an enclosure 1, containing a supply 4 of alkali-metal or alkaline-earth metal, separated by a diaphragm 3 from a discharge space 7 in which are arranged an accelerating electrode 9, an ion-optical system 10 and a collecting electrode 11 to which a load circuit (not shown) may be connected. The enclosure 1 is heated by a winding 5 and contains a heated anode 6 arranged near an aperture 2 in the diaphragm 3 so that uncharged atoms of vaporized metal cannot pass through the aperture without colliding at least once with the anode surface. A platinum anode is suitable for the production of caesium, rubidium potassium, barium, sodium or lithium ions. For some of these metals the anode may alternatively be made of nickel, iron, carbon, molybdenum or tungsten. The ion source may be used as a delay element in an electrical circuit. Specification 745,441 is referred to.
