Presentation

The electron beam quality of a photocathode-based electron source is limited by the achievable mean transverse energy (MTE). The Liouville theorem states that the total emittance of a beam cannot improve as it propagates through an accelerator, only manipulated using lattice optics. Therefore minimising the intrinsic emittance of a photocathode is important. This alongside other factors such...

Presentation

A photocathode composed of a Pb layer deposited on Nb substrate is an attractive solution proposed for fully superconducting, radio-frequency electron gun to be used in the linear accelerator of the European X-ray free electron laser (Eu-XFEL) operating at Deutsches Elektronen Synchrotron (DESY) and in other, similar devices. Much effort has been put in development of deposition and...
