Abstract
In this paper, two comparative experiments have been carried out to study Cs´ effect on the stability of GaAs photocathode. Experiments show that Cs of a certain concentration helps extend the life of photocathode, and the decay of photocathode is not caused by Cs desorption but oxide adsorption.
