Abstract

669,024. Magnetrons. RAYTHEON MANUFACTURING CO. Dec. 3, 1945 [March 27, 1945], No. 32581/45. Class 39 (i). An anode structure 6 for a magnetron comprises a cylindrical copper body 9 having an annular boss 10 from which extends radially a plurality of anode members 11, each anode member being paired with an adjacent anode member to form, with the portion of the anode body lying between said pair of anode members, a first resonant line, and a low impedance member in the form of an arcuate conducting strap 12 connecting each member of each pair of anode members to the nearer member of each adjacent pair of anode members at points 13 intermediate the lengths thereof, portions of the connected anode members together with the low-impedance strap constituting a second resonant line of dimensions different from the first resonant line. The output wavelength is the average of the wavelengths of the two differently dimensioned resonant lines. Each anode member 11 can be provided, in their upper and lower edges, with slots 13 in which, initially, conducting rings may be secured, those portions of the rings which connect adjacent anode members 11 of alternate pairs being subsequently removed, leaving the straps 12. The cathode structure 7 which is coaxial with the anode structure .6 may include a highly electronemissive oxide-coated sleeve 17 heated by a filament having terminals 18, 19 connected to lead-in conductors 20, 21 passing through glass seals 22, 23 fused into pipes 24, 25, threadedly engaged and hermetically sealed in the body 9. Pole-pieces 26, 27 are provided. An output loop 28 projects into the space between any pair of anode members 11 forming one of the longer resonant lines and is connected to a conductor 29, embedded in a glass seal 30 fused into the outer end of a pipe 31 threadedly engaged and hermetically sealed in the body 9. Specifications 588,185, 588,916 and 590,547 are referred to.
