CBB Seminar: N. Moody and J. Smedley (LANL)

The LANL-BNL Cathode Collaboration

Abstract: The Applied Cathode Enhancement and Robustness Technologies (ACERT) capability at LANL and the in-situ x-ray analysis growth chamber at BNL are two of the premier tools available for development of photocathode technologies. We are following a model of innovation and collaboration to move cathodes from lab to application, guided by theory, modeling, and experimental validation. This presentation will focus on two recent technology advances – cathodes with “atomic armor”, single monolayers of coatings to the cathode surface and/or substrate to improve lifetime and enable operating in inferior vacuum, and highly crystalline CsTe, providing evidence that better crystallinity can improve QE while supporting an ultra-smooth surface. We hope to engender both technical discussion in these areas and open the door to future collaborations.
