摘要：
The paper introduces an impregnated barium scandate cathode, which uses scandium, barium, calcium, aluminum carbonates as emission materials which are impregnated into the tungsten matrix substrate directly. The preparation process is described. The cathode can be used not only to several types of microwave tubes successfully, but also to large demountable traveling wave linear accelerators reliably. The cathode can be activated, after exposure to air several times and still keeps its emission ability.
