About EuroFEL
EuroFEL is part of the ESFRI Roadmap since 2006. The preparatory phase of EuroFEL (IRUVX-PP) prepared the establishment of the EuroFEL Consortium to link FEL & SPS facilities in Europe closer together. IRUVX-PP has been funded by the European Commission under FP7 from April 2008 to March 2011.

WP8 - FEL Source

Objectives

The basic research and development areas for individual FEL facilities have been addressed by the EUROFEL Design Study, ending at the end of 2007. Building on these successful developments and the complementary expertise of the partners, the present work package focuses on technical preparatory work that is of critical importance for the timely and costeffective construction of components which are mandatory for the stable operation of all new FEL sources. They include an optical synchronisation system with 10 femtosecond precision (WP8.1), diagnostics and feedback systems for high precision control and stabilization of the longitudinal electron bunch profile and its arrival time (WP8.2) and a joint approach to seeding with High Harmonic Generation (HHG) lasers.
