The paper is a review of tungsten-base dispenser cathodes. Particular emphasis is placed on the many factors that contribute to the performance of a dispenser cathode. The review includes a history of the evolution of the modern dispenser cathode, fabrication techniques and their influence on cathode performance, state-of-the-art performance characteristics for various types of dispenser cathodes and possible future developments for dispenser cathodes.
