The study showed that the maxim secondaryemissioncoefficient of rare earth molybdenum cathode materials was 2.45, which meet the requirement (>2.0) of magnetron to the cathode materials.
This paper derived the formulation for the real efficient emissioncoefficient of secondary electron under the condition that high energy primary electron incident on metal obliquely.
