Feasibility Study of Multi Turn ERL Based Synchrotron Light Facility

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 pape
