EUROFEL 2005 - 2007


2005 - 2007



- Superconducting cw or near cw linacs

EUROFEL was an European FEL Design Study proceeded with the Sixth Framework Programme of the EC from 2005 to 2007. Results (publications, reports, deliverables) are presented on the EUROFEL webpage (


Superconducting rf guns:

Presently no electron injector exists that can both operate cw and provide the combination of low-emittance and high bunch charge/current required by the proposed FELs and ERLs.

Two systems will be investigated:

I. the ELBE superconducting injector currently under construction,

II. the design of the INFN superconducting split injector system.
