A first principles analysis of photoemission is developed to explain the lower than expected
rms transverse electron momentum measured using the solenoid scan technique for the …

This volume, which is the first in the EuCARD Editorial Series on “Accelerator Science and
Technology”, is closely combined with the most advanced particle accelerators–based on …

We report on the progress and status of an electron RF-gun* made of two superconductors:
niobium and lead [1]. The presented design combines the advantages of the RF …

Energy recovery linacs (ERLs) are a type of accelerator that works by decelerating the
initially accelerated beam once it has been used to recover its energy back into the radio …

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 …

SRF Gun Cavity is an ongoing accelerator R&D project at DESY, being developed since
several years. Currently several SRF gun cavity prototypes were simulated, built and tested …

R&D programs based on various approaches, at BNL, FZ-Rossendorf, Beijing University
and AES generate optimism that low emittance continuous wave operating SRF-guns and …

The ultimate goal of our presented here effort is to build a hybrid superconducting Nb
photoinjector with the cathode made of lead, which demonstrates superior quantum …

The Polish Free Electron Laser, PolFEL was proposed more than decade ago and at that
time was accepted for the Polish Roadmap for Research Infrastructures. The facility was …

One of the frontiers in FEL science is that of high power. In order to reach power in the
megawatt range, one requires a current of the order of one ampere with a reasonably good …
