New requirements of the Jülich Electric Dipole Moment Investigation (JEDI) experiment requires a RMS beam orbit distortion smaller than 100 um. This requirement lead so far to the replacement of the BPM readout electronics, an introduction of a slow beam orbit correction and feedback system and the re-alignment of the magnets. All three projects are close to completion, therefore first results are presented.
