Abstract
The emission and surface characteristics of a dispenser cathode coated with Re are studied. It is found that the dispenser cathode coated with Re has both higher current density and more uniform distribution of emission than the S-type cathode. The Auger images of Ba show that the Ba distribution on the surface of the cathode coated with Re is more uniform than that on the surface of the S-type cathode. The analytical results by XPS and low energy AES show that the Ba on the surface of the cathode coated with Re has stronger metallic property than that on the surface of the S type cathode.
