Abstract

Alkali antimonide cathodes have the potential to provide high quantum efficiency for visible light and are significantly more tolerant of vacuum contaminants than GaAs, so they are attractive for use in high-average current photoinjectors to generate high quality electron beams. We have grown multi-alkali cathodes on [100] silicon substrates, simultaneously acquiring in-situ X-ray diffraction (XRD) and X-ray reflection (XRR) data throughout the growth process. Correlations between cathode structure and growth parameters and the resulting quantum efficiency (QE) have been explored.
