      abstract     = {One of the fundamental questions of modern particle physics
                      is the existence of finite electricdipole moments (EDM) of
                      the hadrons. In case of charged particles, like protons and
                      deuterons,the proposed method is the precise determination
                      of the precession of the beam polarization vec-tor in a
                      storage ring. For that purpose, the JEDI (Jülich Electric
                      Dipole moment Investigations)collaboration is developing a
                      precise polarimeter detector based on LYSO scintillator
                      coupled toSiPM modules. They are capable of stopping almost
                      300 MeV elastically scattered deuterons andprotons.
                      Measuring the kinetic energy of the scattered projectiles
                      ensures the accurate reactionidentification leading to a
                      precise polarization determination.To create the long-term
                      reliable detector system, we have performed four iterations
                      of the detec-tor development (three of them since last CALOR
                      2016). Currently, we are operating 52 LYSOmodules with a
                      dedicated dead-time less sampling ADC readout system. The
                      modules are verycompact, due to modern high pixel density
                      SiPM readout. A summary of all test beam times andthe
                      accumulated experience will be presented and discussed.},
