The particle accelerator and materials research communities have long enjoyed a synergistic relationship, dating back at least to the first studies of materials using synchrotron radiation produced at particle accelerators. At present, a new generation of advanced synchrotrons and x-ray free electron lasers are emerging. These advances are coincident with a push in materials research to understand phenomena at unprecedented length and time scales, including a focus on the mesoscale properties of materials. Further, photons are not the only accelerator-produced particles of interest to materials research, both as a probe and as a means of generating perturbed states of matter. This presentation will not only reprise recent progress, but also speculate about future opportunities.

Chris Pierce's B Exam (Internal)

Oct 07

2:30pm - 3:30pm, Zoom (meeting ID in Invitation email) and 700 Clark Hall

Title: Towards High Brightness from Photocathodes

Description: Bright electron beams, as well as the technologies they power, are among the most powerful probes of matter at atomic length and time scales. Many of these systems and techniques, however, are limited in performance by the achievable brightness of modern particle accelerators. In this talk, Chris will first show in simulation that better photocathode technologies are a viable path towards improving beam brightness. Then, he will present new research on a diverse set of topics related to these electron source improvements. Future directions of study in this field will be discussed last.
