USING OF LAPPING PROCESS FOR OPTIMIZATION OF PASSIVE SURFACE'S RESONANT CAVITIES OF ANODIC BLOCK FROM POWER MAGNETRONS

摘要

The paper has presented an achievement proceeding of resonant cavity optimized for power magnetrons with anodic bloc had multiple cavities type vane or slit. These have a metallic structure, realized from a paramagnetic non-ferrous metal, with higher purity, on which has placed covered layers of metal-metal, respectively metal-insulation-metal. The method consists in doing of super-finishing operation of lateral surface's resonant cavities of anodic block, which assured a orientation mode of roughness parallel with direction of electric skin current, and shorten of skin current travel due to minimize of power loses by Joule-Lentz effect. The consequences of this effect are enhance equivalence resistance and surface impedance of resonant cavity, and realized a better quality factor of magnetron.
