The Relativistic Ultrafast Electron Diffraction and Imaging (RUEDI) facility has been recently approved by the UKRI Infrastructure Fund to be a new ultrafast science capability for the UK based at Daresbury Laboratory. It will deliver single-shot, time-resolved, imaging with MeV electrons, and ultrafast electron diffraction down to 10 fs timescales. RUEDI is being designed to enable the...
Photocathodes play an integral role in the development of electron accelerators and photon detectors. In spite of having an ultrasmooth photocathode developed by a co-deposition process [Gaowei et al (2019)], there are still limitations on emitted beam brightness by the surface and bulk disorder of the polycrystalline photocathode material. Epitaxial growth of photocathodes has the potential...
At Helmholtz-Zentrum Berlin photocathodes are developed as electron source for the SRF-photoinjector of the superconducting RF electron accelerator laboratory (SEALab). Sodium-Potassium-Antimonide (Na-K-Sb) photocathodes are grown and characterized by spectral response and X-ray photoelectron spectroscopy in the photocathode lab, but until now there was no device to analyze the mean transverse...
