Summary This project will study the properties of advanced cathodes for high-average-current, high-brightness injectors. In particular, the quantum efficiency of dispenser photocathodes will be measured as a function of time and position on the cathode surface. Studies to determine the ability of the cathode to regenerate the quantum efficiency following damage is also of interest.
Diamond pyramid field emission cathodes will also be investigated, for Ion-term operational performance, in particular emission uniformity and stability, as well as resistance to ion impact damage.
