Abstract

Polarimetry is a key field of interest if an experimental program with polarized electron and photon beams is planned. The new photo injector recently installed at the superconducting 130 MeV Darmstadt electron linac S-DALINAC provides polarized electrons from a GaAs cathode for nuclear structure studies at low momentum transfers. The degree of polarization needs to be measured at different positions close to the experimental sites and at different energies ranging from 100 keV up to 130 MeV. A 100 keV Mott polarimeter had been set up and commissioned at a test stand of the polarized source prior to implementation, while a 5-10 MeV Mott polarimeter is currently under construction and simulations for a 50-130 MeV Møller polarimeter are going on. Compton transmission polarimeters are foreseen to monitor polarization during experiments.
