A multi-turn energy recovery linac -based light source is under discussion. Using the superconducting Linac technology, the Femto-Science-Factory (FSF) will provide its users with ultra-bright photon beams of angstrom wavelength. The FSF is intended to be a multi-user facility and offer a variety of operation modes. The driver of the facility is a 6 GeV multiturn energy recovery linac with a split linac. In this talk we discuss designs of the optic in the linac and compare different schemes of beam acceleration: a direct injection scheme with acceleration in a 6 GeV linac, a two-stage injection with acceleration in a 6 GeV linac, and a multi-turn (3-turn) scheme with a two-stage injection and two main 1 GeV linacs. Construction costs and beam break up instability were the key points for comparison.

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 mkm rad 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 advance.

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.
