Data comparisons were made between scandate cathodes from several groups world-wide. Processing and test parameters were identical between cathodes. Cathode emission performance was measured in close-spaced diodes. This data will be presented. In addition, surface and cross-sectional morphology via SEM after sintering, impregnation, and activation are shown. Furthermore, the cathodes were installed in Pierce gun testers and comparison data taken at 100 amps/cm2. Life tests were performed and knee point migration on each cathode was measured. Crush tests on the cathode matrices were performed to gauge mechanical strength. Liquid-Solid versus Liquid-Liquid processes are evaluated.
