摘要
概述了近年来钪系阴极的进展和研究现状 ,介绍了钪酸盐阴极、顶层钪系阴极、膜钪系阴极、钪钨基底钡阴极的性能、特征及相应工作机制。根据钪系阴极的研究成果 ,提出了钪钨基底钡阴极材料研究的一些设想。
The advance in the recent research of Sc type cathodes was reviewed. The performance, characteristics and the emission mechanism of the impregnated cathode with scandium oxide, the top layer scandate cathode, the thin film scandate cathode and barium metal film with Sc W matrix cathode were introduced. Based on the development experience and the study fruit of scandate emitters, we puts forward the new speculations on the study of barium metal film cathode with Sc W matrix.
