| Popis: | Electric Dipole Moments (EDMs) violate parity and time reversal symmetries. Assuming the CPT-theorem, this leads to CP violation, which is needed to explain the matter over antimatter dominance in the Universe. So far no direct EDM measurement for charged hadrons have been performed. The goal of the JEDI collaboration (Jülich Electric Dipole moment Investigations) is to measure the EDM of charged particles. The measurement of EDMs of charged hadrons can be performed in storage rings by observing a polarization build-up proportional to the EDM. Due to the smallness of the effect many systematic effects leading to a fake build-up have to be studied. A first step on the way for an EDM measurement is the investigation of systematic errors at the storage ring COSY (COoler SYnchrotron). One part of these studies is the control of the beam orbit with high precession. Therefore a concept of new Beam Position Monitors (BPMs) based on magnetic pick-up coils are used. The main advantage of the coil design is the high response to bunched beam frequency signal and the compactness of the coil itself. First measurement results of such a BPM accelerator environment will be presented. Proceedings of the 5th Int. Beam Instrumentation Conf., IBIC2016, Barcelona, Spain |
