A VUV-FEL FOR 4GLS: DESIGN CONCEPT AND SIMULATION RESULTS

A Free-Electron Laser operating in the photon energy range 3-10eV is a component of the 4th Generation Light Source (4GLS) proposal at Daresbury Laboratory in the UK. In this paper we present a current design proposal which is based on the Regenerative Amplifier FreeElectron Laser (RAFEL) concept. We also present simulation results which illustrate the potential performance of the device.
