Abstract: The surface analysing results of barium cathode(oxide and metal- multihole scandate cathode)and thoriated-tungsten cathode by ion sca- ttering spectrometry were reviewed in this paper. Based on the results,a better understanding of operating prineiple, operating process and the optimum technical processing of the catho- des has been achieved.
