HIGH EMISSION PERFORMANCE IMPREGNATED DISPENSER CATHODE
《Journal of Electronics(China)》2013年第4期417-422,共6页Yin Shengyi Peng Zhen Zheng Qiang Wang Yu 
Supported by the National Natural Science Foundation of China (No. 60871053);the Major State Basic Research Development Program of China (No. 2013CB328901)
In order to obtain higher emission performance than that of a traditional M-type cathode, we have developed a new type impregnated dispenser cathode. The new cathode is impregnated with a new active substance with mol...
