Abstract In this paper, the structure, the conditions of operation and the performances of a cesium ion source have been described. And the mass-spectrums of residual gases du-ring operation have been shown. The erperimantal results sho,w that there are some advantages of this cesium ion source, such as having a simple structure, easy to operate, well directed, and giving a reproducible yi eld for practical uses. It is a practical cesium ion source with good directivity.
