Investigation of the high performance Nickel-matrix Oxide cathode

This paper introduces the investigation of high performance Nickel-Oxide cathode for high powerw with long pulse. The authors also discuss the key factors affecting the performance of cathode, including the cathode surface, porosity of Nickel matrix, and distribution of temperature, etc. the authors employ the special mould to change the density and roughness of cathode surface. Finally, the magnetron assembling the cathode has stable performance.
