  The approach to the MYRRHA Control System (CS) development will be described. The effort, time and resources needed to develop the control systems are often underestimated by a significant factor. This brings unnecessary setbacks to the projects. Understanding CS requirements at an early machine conception stage is paramount for adequate CS design. Awareness of sheer project size and interdisciplinary complexity is imperative for successful project execution. In the first part of the paper the MYRRHA roadmap, milestones, status and its future needs will be presented with an emphasis on the phased approach leading to the 100 MeV program. The second part of the paper will give the status of the MYRRHA CS development within this phased approach. Best practices for coherent integration will be discussed. The CS should provide a flexible framework for the integration of devices. Interfaces and services need to be defined early in the integration process, and the number of different interfaces and platforms should be kept to a minimum. The implications of the choice of technologies and of SW development processes on the overall reliability and availability have to be established.

  The Cooler Synchrotron (COSY) at Forschungszentrum Jülich is currently carrying out the preparation for a direct measurement of the electric Dipole Moment (EDM) of the deuteron using an RF Wien filter*,**. In a magnetic storage ring with the spin vector aligned along the direction of motion, the EDM manifests in a buildup of the vertical spin component. Besides this signal, radial magnetic fields due to a distortion of the vertical closed orbit can produce a similar signal. This signal is a systematic limit of the proposed measurement procedure. Based on simulation studies***, a vertical closed orbit distortion with a RMS smaller than 0.1 mm is required to achieve a sensitivity of 10-19 e.cm or better. In order to accomplish this challenging goal, a slow orbit feedback system was proposed and recently commissioned at COSY. The design and commissioning results will be presented, and the future plan will also be discussed.
