摘要

本文介绍了一种以钪、钡、钙、铝等碳酸盐为发射材料，直接浸渍在钨基衬底上的浸渍钡阴极。介绍了制备工艺。该阴极不仅可以成功地应用于多种类型的微波管，而且可以可靠地应用于大型可拆卸行波直线加速器。阴极暴露在空气中几次后仍能被激活，并保持其发射能力。

Preparation of impregnated barium scandate cathode and its application

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.
