Numerous beam diagnostics systems, with the BPM system considered the most important one, are envisaged for the High Energy Storage Ring (HESR) within the FAIR Project. The BPM design, the corresponding test bench, HESR BLM studies at COSY, status of the ionization profile monitor and other subsystems are presented.

The cyclotron Julic is used as an injector for the COSY synchrotron and storage ring of 183 m circumference. The 95 m long injection beam line (IBL) transports polarized and unpolarized H-/D- ions which are injected into the ring via multi-turn stripping injection. 8 profile monitoring stations are installed in the IBL. Each station contains two harps having 39 wires at 1mm spacing. Each harp is read out by a multichannel pico-amperemeter electronics designed by iThemba LABS, South Africa, delivering profile data to the COSY control system. The technical details of the upgrade and recent beam profile measurements are presented.

For the planned Electric Dipole Moment (EDM) precursor experiment at the COSY synchrotron and storage ring an accurate control of the beam orbit is crucial. The required beam position measurement accuracy demands an upgrade of the BPM readout electronics. The BPM system currently in operation is described. The required performance and the possible upgrade scenarios are discussed.
