      abstract     = {The Jülich Electric Dipole Investigation (JEDI)
                      collaboration aims at the measurement of a charged particle
                      Electric Dipole Moments (EDM) for protons and deuterons with
                      a statistical sensitivity of ~ 1E-29 ecm in a storage ring
                      based experiment. This should be achieved by an interaction
                      of the EDM with a radial electric field that causes a
                      horizontal polarization build-up in a previously vertically
                      polarized, coherent beam. To measure this minuscule
                      polarization build-up, a designated polarimeter based on
                      heavy LYSO crystals was developed. The polarimetry reaction
                      employed to measure the polarization is the elastic
                      scattering of polarized particles off an unpolarized carbon
                      target. The measured scattering asymmetry can be related to
                      the beam polarization if the analyzing power of the reaction
                      is known. This work consists of two major parts. In the
                      first part, the analysis of the database experiment, which
                      aimed at the measurement of the vector analyzing power for
                      the deuteron carbon elastic scattering reaction using seven
                      different beam energies, is presented. This experiment was
                      performed at the Cooler Synchrotron (COSY) accelerator
                      facility at the Forschungszentrum Jülich in Germany.
                      Different methods for the extraction of the scattering
                      asymmetry are presented and the result for the extracted
                      deuteron carbon vector analyzing power and the unpolarized
                      differential cross section for this reaction are given. In
                      the second part, the iterative development process of the
                      designated polarimeter is described in detail. For this
                      device, a modular approach was chosen based on individual
                      detector modules. These modules consist of an inorganic LYSO
                      scintillator crystal that is optically coupled to a SiPM
                      array that converts the scintillation light into an electric
                      signal that can be processed by fast flash-ADC. Multiple
                      properties of these modules such as resolution or linearity
                      were tested and proved the concept to be well suited for the
                      final designated polarimeter.},
