Shanghai high repetition rate XFEL and Extreme light facility (SHINE) is designed to be driven by an 8 GeV continuous wave (CW) superconducting RF (SRF) linac with MHz repetition rate high brightness electron beam. SHINE started electron source installation in 2023, and the first 100 pC photoelectron beam successfully reached the ~1 MeV beam dump at 1 MHz rate in December of 2023. After that,...
Low Mean Transverse Energy (MTE) photocathodes play a crucial role in enhancing the performance and capabilities of Free Electron Lasers (FELs) and other advanced electron accelerator applications, enabling groundbreaking scientific research across diverse fields. Due to the requirements for the high charge density, disordered nature of photocathode materials, surface roughness and work...
As part of an international collaboration between PSI and INFN, two novel C-band RF photoguns have been designed and realised in the context of the IFAST programme. These RF photoguns aim to push the brightness of the next generation of FELs through an increased cathode gradient achieved through reducing the filling time of the device. In this work, we demonstrate how these newly developed...
We commissioned a new type of photocathode laser systems (NExt generation PhotocAthode Laser NEPAL) at the superconducting XFELs FLASH and EuXFEL.
The NEPAL lasers provide temporal and spatial shaped picosecond deep UV pulses enabling very low emittance electron beams, which are needed for highest X-ray photon energies. At EuXFEL we have demonstrated an excellent transverse projected...
