Abstract
A dispenser cathode life prediction model is presented that provides a method of calculating how the cathode current changes with time and temperature Both the tungsten dispenser cathode and the metal coated dispenser cathode are considered. The model is compared to accelerated life test data taken in TWT type guns for tungsten dispenser B-type and for the osmium-ruthenium dispenser M-type cathodes.
