It has been operated as Germany¿s first energy-recovery linac (ERL) in 2017***. The electron beam is produced either in a thermionic gun or a DC photo-gun using GaAs as cathode material****. A new project foresees to use the S-DALINAC for Laser Compton Backscattering (LCB) to produce a monochromatic high-energy photon beam for nuclear photonics applications in photonuclear reactions and atomics physics experiments. Besides this LCB will be used as an additional diagnostic tool for determining electron beam energy and the energy spread at the third recirculation of the S-DALINAC, when the maximum reachable energy at this point (98.8 MeV) yields a scattered photon energy of 179.7 keV. An overview over the desired laser system for LCB at the S-DALINAC will be given, and simulations for the layout and the estimated output of the Compton-backscattering light source will be presented.
