METHOD FOR MANUFACTURING AND ASSEMBLING ELECTRON GUN WITH ANODE UNIT OF O-TYPE MICROWAVE TUBE Russian patent published in 1997 - IPC

FIELD: electronic engineering. SUBSTANCE: method involves assembly of cathode, gate electrode, and anode with their holders in cermet package and connection of electron gun to tube through orienting rods. Base surface of anode holder is first to be machined, then locating surfaces of other holders are adjusted strictly in parallel to base surface of anode holder; assembly is started from installation of anode simulator on this base surface and locking it in position on base surface of anode holder; then cathode and gate electrodes are assembled and welded in turn to their respective holders on cermet package. EFFECT: facilitated procedure. 4 dwg
