Title: Cathode for magnetron
Inventor: SATO YOSHIHIKO
IPC: H01J23/05
Filed: 1985-02-06
Abstract: PURPOSE:To enable the stable emission of electrons for a long time, by integrally providing a plurality of separated projections at nearly regular intervals on the peripheral surface of a cathode sleeve between end flanges, and filling an electron emission substance in the space between the projections. CONSTITUTION:A plurality of truncated pyramids 10 are integrally provided as separated projections regularly on the peripheral surface of a sleeve between end flanges 3, 4. An electron emission substance 7 is filled in the space between the truncated pyramids 10. Since the truncated pyramids 10 are formed integrally with the sleeve 2, the pyramids and the electron emission substance 7 are unlikely to drop off the sleeve, so that the effective electric resistance and thermal resistance are unlikely to increase. Even if the thickness of the substance 7 is reduced due to its erosion or evaporation, the surface area of the substance which contributes to the emission of electrons is not much changed to expose much of metal to lower the efficiency of the electron emission. Since the efficiency of the electron emission and the electric conductivity of the substance 7 are unlikely to drop, stable operation is enabled for a long time.
