Abstract
PURPOSE: To keep the contact of a radiating fin with an anode of a magnetron to maintain radiation from the radiating fin at an elevated temperature by forming a plurality of radial slits on the radiating fin from the contact part outward.
CONSTITUTION: A magnetron comprises an anode 3 having anode plates 2, a cathode 1 disposed at the center of the anode 3, and a radiating fin 8 extending perpendicularly to the axis of the anode 3 and attached to the periphery of the anode 3. A plurality of radial slits 10 are formed on the radiating fin 8. The lengths (1) of the slits 10 are longer than ξ defined by a formula; ξ=a.tanh.1/2a. Where a= (δ.K/2h), δ=the thickness of the radiating fin, K=heat conductivity of the radiating fin, h=heat conductivity between the ambient air. The heat expansion of the area within an oval (A) on the radiating fin 8 fastly binds the radiating fin 8 to the anode 3.
