Abstract

A RE₂O₃-Mo cathode which contains Lu₂O₃ and Y₂O₃ with a certain weight ratio was made using a Sol-Gel technique and the spark plasma sintering technique. The maximum secondary emission yield (deltam) of this cathode could reach 4.6 while the activation temperature is only 900degC.

Y2O3-Lu2O3-Mo阴极的二次发射性能

采用溶胶-凝胶技术和火花等离子烧结技术制备了含有一定质量比的Lu2O3和Y2O3的RE2O3-Mo阴极。当活化温度仅为900℃时，该阴极的最大二次发射产率(delta)可达4.6。
