AB  - There is a matter-antimatter asymmetry observed in the universe that cannot  be  explained  by  the  Standard  Model  of  particle  physics.   To  resolve  that problem  additional  CP  violating  phenomena  are  needed.   A  candidate  for  anadditional CP violating phenomenon is a non-vanishing Electric Dipole Moment(EDM) of subatomic particles.  Since permanent EDMs violate parity and timereversal symmetries, they also violate CP if the CPT-theorem holds.The Jülich Electric Dipole moment Investigation (JEDI) Collaboration works on a direct measurement of the electric dipole moment (EDM) of protons and deuterons  using  a  storage  ring.   The  JEDI  experiment  requires  a  small  beam orbit RMS in order to measure the EDM. Therefore an ongoing upgrade of the Cooler  Synchrotron  (COSY)  is  done  in  order  to  improve  the  precision  of  the beam position.  One of part of this upgrade is to determine the magnetic center of the quadrupoles with respect to the beam position monitors.  This can be done with the so called beam-based alignment method.  The first results of the  beam  based  alignment  measurement  performed  in  February  2019  will  be presented.
