Abstract:
A magnetron has an anode 3 surrounding a tubular hollow cathode 4 which contains a heater 9. The cathode is supported by radial arms at each end. At one end of the cathode, the heater is supplied with one terminal of its D.C. supply by means of a radial arm 5, which also serves to support that end of the cathode. The arm has a portion 5a offset towards the cathode, and a cover of conducting material is interposed between the heater connection and the adjacent end wall 1 of the vacuum envelope. The cover may have a folded portion so that it can be carried by the arm.
