Development of beam position monitors for storage rings — •Falastine Abusaif for the JEDI collaboration — Juelich Forschungszentrum IKP-2 — RWTH Aachen University, Physics Institute B, Germany

The Juelich Electric Dipole Moment (JEDI) Collaboration is presently preparing for a first direct measurement of the deuteron Electric Dipole Moment (EDM) in the COoler SYnchrotron (COSY). A non-vanishing EDM signal would provide a new source for CP violation which could answer the mystery behind the matter abundance in the universe. The EDM is expected to be very small that can be easily mimicked by fake signals.

In accelerator physics, understanding and controlling beam dynamics can be considered as important step towards an EDM measurement. Beam position monitors are needed for tracking beam transverse coordinates and to maintain overall stable orbit.

A new type of Beam Position Monitor (BPM) which is based on a Rogowski pickup coil was developed lately and installed at COSY. In this talk , results of different tests and calibrations that were performed in the lab will be presented. In addition to the first commissioning results for the installed BPM coil during the November/December 2018 beam time.
