In the subsequent experiments, when the LaBe cathode emitted continuously and the current is 40uA, the minimum diameter of electron-beam spot recorded was 22 um. While the LaB6 emitted pulse, the minimum diameter of the focus decreased and wasnt more than 15um. The reason is that the heat accumulated on the foil-film, which enlarged the focus dimension, reduced remarkably.

当阴极采取连续发射电子的工作模式(发射电流40μA)时，记录测量到的最小电子束焦斑直径不大于22μm；而在相同条件下，以脉冲方式发射电子束时，其焦斑直径不大于15μm，原因是短时间的电子轰击减小了靶面的热堆积效应等。
