Development of a 130 MeV Møller-Polarimeter at the S-DALINAC* — •Thore Bahlo1, Christian Eckardt1, Joachim Enders1, Florian Hug1, Norbert Pietralla1, and Oliver Haas2 — 1Institut für Kernphysik, TU Darmstadt, Darmstadt, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany
The Superconducting Darmstadt Linear Accelerator (S-DALINAC) can be used to accelerate polarized electron beams which are produced by the S-DALINAC Polarized injector (SPIN). In order to measure the polarisation of the electrons several devices along the beamline, like a low-energy Mott polarimeter and a Compton transmission polarimeter have already been installed and successfully tested.
For kinetic energies of more than 50 MeV these types of polarimeters are not applicable. Therefore a new high energy Møller-Polarimeter has been developed. In this talk we will present the design of the used dipole magnet and the layout of the polarimeter with respect to the strongly limited available space.
