Description
The ELSA facility at the University of Bonn uses a storage ring to accelerate polarized electrons up to 3.2 GeV. To monitor the polarization degree of the stored beam a Compton polarimeter is used to analyze the profile of the back-scattered beam of gamma rays. In addition to a silicon microstrip detector with vertical resolution, state-of-the-art pixel detectors are tested for both, polarimetry and monitoring of the electron beam’s long-term position and angular stability. The current status of the polarimeter performance is presented.
