  • A Aluminate dispenser cathode with Y2O3 have been investigated by using modern surface analysis techniques (AES, XPS, SEM and THEM). The Surface topography, Surface chemistry and emission properties of the cathodes activated in situ have been obtained. The experimental results and activation mechanism are also discussed.
