The superconducting Darmstadt linear electron accelerator (S-DALINAC) of the Institute for Nuclear Physics at Technische Universität Darmstadt delivers electron beams in cw-mode with energies up to 130 MeV. The accelerator consists of a 10-MeV injector and a 30-MeV main linac where superconducting 3-GHz microwave cavities are operated at a temperature of 2 K for beam acceleration. With three recirculation beamlines the main linac can be used up to four times. To improve the energy spread and the energy stability of the beam a new scrapersystem has been developed and installed. It changes the extraction beam line into a dispersion-conserving chicane consisting of four dipole magnets and three scrapers. The system includes scraping of x- and y-halo in two positions as well as improving and stabilizing energy spread on a dispersive part. We will present the design of the system and report on its installation into the accelerator complex.
