摘要：

The Julich Electric Dipole moment Investigation (JEDI) Collaboration works on a measurement of the electric dipole moment (EDM) of charged hadrons using a storage ring. Such a dipole moment would violate CP symmetry, providing a possible option for physics beyond the Standard Model. The JEDI experiment requires a small beam orbit root mean square (RMS) in order to control systematic uncertainties. Therefore an ongoing upgrade of the Cooler Synchrotron (COSY) at Forschungszentrum Julich is done in order to improve the precision of the beam position. The first results of the beam based alignment method, that was tested with one quadrupole in the ring, will be discussed.
