| Popis: | At the Superconducting Darmstadt Linear Accelerator S-DALINAC it is possible to accelerate electron beams to a maximum energy of up to 130 MeV. In the S-DALINAC Polarized Injector SPIN polarized electrons with a polarization of up to 86% can be produced. The polarization can be measured with two already mounted Mott polarimeters in the injector beamline where the electrons can have energies of up to 10 MeV. To allow polarization measurements behind the main accelerator a Moeller polarimeter suitable for energies between 50 MeV and 130 MeV is currently being developed. The rather low and variable beam energies result in a big and also variable scattering angle distribution. Combined with strict spatial boundary conditions at the designated mounting area necessitate a very compact set-up for the polarimeter. In addition to an overview over the planned polarimeter we will present drafts of the target chamber, the beam separation chamber including a angle-defining aperture and the separation dipole as well as the beamline to the detectors and the beam dump.
