Description
A copper photocathode based on bulk Cu(100) substrate
with a 50 𝜇m-diameter nanostructured region was fabricated
and integrated into an S-band radio-frequency gun. We
report the procedure for production and preparation of high-
quality copper cathodes with nanostructured area compatible
with state-of-the-art S-band RF gun. Experimental results
indicate absence of increased dark current up to 70 MV/m
at the cathode.
Funding Agency
Work performed in the framework of R&D for future accelerator operation modes at the European XFEL and financed by the European XFEL GmbH.
