Abstract

PURPOSE: To simplify the fabrication of an electron-range magnetron of longitudinal spray cooling structure by arranging a heat sink, made round into a cylindrical shape, inside of a fixing ring and by pushing a bulb inside of the heat sink.
CONSTITUTION: Cooling body 18 in a comb-tooth shape is formed in one and made round in a cylindrical shape at the time of fabrication before being set inside of fixing ring 19. Then, mount 21 is set which has core metal 20 shown by the dotted lines, and the inner diameter of heat sink 18 is made close to the outer diameter of anode cylinder 16. Afterwards, main bulb body 17 with a permanent magnet arranged inside of anode cylinder 16 is pushed into the center hole of head sink 18. In this case, core metal 20 can be pressed down easily. In addition, forming taper part 16a at the edge of anode cylinder 16 simplifies pressure insertion.
