Supply mechanism of barium in the barium-tungsten cathode

SONG Jian-hua~1,ZHANG Hong-wei~2(1.Anhui Technical College of Mechanical and Electrical Engineering,Wuhu 241000,China;2.Anhui Huadong Photoelectric Technology Institute,Wuhu 241000,China)  
According to the theoretical analysis in Momentum,Thermal and Mass,the problem of supply mechanism(Momentum;Thermal;Mass) of Barium in the barium-tungsten cathode was dealt with.Results show that the supply mechanism mainly depends on the structure,physical performances of the porous medium and the characteristics of Barium.The research helps us to deeply realize the emitted mechanism of cathode.
