Sažetak

The A2-collaboration at the Mainz Microtron MAMI measures photon absorption cross sections using circularly and linearly polarized photons up to an energy of 1.5 GeV. The photons are produced in the 'Bremsstrahlung' process. In the years 2005/2006 the Crystal Ball detector, with its unique capability to cope with multi photon final states, was set up in Mainz. In 2010, the experimental apparatus was completed by the installation of a polarized target. The horizontal dilution refrigerator of the Frozen Spin Target was constructed by and is operated in close cooperation with the Joint Institute for Nuclear Research in Dubna, Russia. The system offers both longitudinally and transversely polarised protons and deuterons.
