Abstract:
Energy Recovery Linacs (ERL) have been discussed as drivers for synchrotron radiation facilities in X-ray region for over a decade. The first proposal for a multi-turn ERL as a next generation synchrotron light facility was in 1997. Since then great advances in ERL technology and high brightness electron source development were achieved, ERL-based high power free electron infrared laser at JLab and the demonstration of multi-turn energy recovery at BINP. The feasibility of an X-ray ERL-based light source seems more and more realistic. An overview of the design of a multi-turn ERL under development at Helmholtz Zentrum Berlin (FSF – Femto-Science Factory) is given in this paper.
