Start to End Beam Dynamic Simulations for Femto Science Factory Feasibility Study

Design studies for a future multi turn ERL based light source at HZB are being investigated. The Femto Science Factory will provide its users with ultra bright photons of angstrom wavelength at 6 GeV. The FSF is intended to be a multi user facility and offer a wide variety of operation modes. A low emittance 0.1 mrad mode will operate in conjunction with a short pulse 10 fs mode. This paper reports on the first results of the start to end beam dynamic simulations for both modes. Higher order geometric and chromatic aberration terms have been suppressed using both multipole magnets and biased off crest acceleration. The influence of the collective effects coherent synchrotron radiation on the transversal emittance is minimised by adjusting the horizontal phase advanc

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

Feasibility study of an ERL based GEV Scale multi turn ligth source

A new generation of particle accelerators based on an Energy Recovery Linac ERL is a promising tool for a number of new applications.
