Cesium-based photocathodes, such as cesium-telluride, are commonly used as electron sources in particle accelerators. Yet, precise control over these materials is hindered by challenges in regulating their crystal structure and stoichiometry during synthesis. While ab initio methods such as density functional theory (DFT) can successfully complement experimental efforts, they also require...
In this presentation, I will give a brief overview of some of the established and productive methods for measuring the transverse and longitudinal energy spreads from photocathode electron sources (Mean Longitudinal Energy and Mean Transverse Energy, or MLE and MTE respectively). These quantities represent the intrinsic emittance of the photocathode electron source. The generation of a...
