Modeling the evaporation rate of cesium off tungsten based controlled porosity dispenser photocathodes
The evaporation of cesium from a tungsten surface is modeled using an effective one-dimensional potential well representation of the binding energy. The model accounts for both local and global interactions of cesium with the surface metal as well as with other cesium atoms. The theory is compared w...
