At the superconducting 130 MeV Darmstadt electron linac S-DALINAC [1] a source of polarized electrons [2] is being installed.
Polarized electrons are produced by photoemission from a negative electron affinity strained superlattice GaAs cathode and preaccelerated to 100 keV. With a Wien filter and Mott polarimeter in the beam line the polarization is manipulated and measured. For beam diagnostics wire scanners, fluorescent screens and a coaxial Faraday cup are included. To measure the beam polarization at higher energies, a 5-10 MeV Mott polarimeter and a 50-130 MeV Møller polarimeter as well as a Compton transmission polarimeter will be installed.
We report on the status of the implementation and show plans for future development and experiments.
