Proton Synchrotron Straight Section 85

At the left, between the pole pieces of the bending magnet, one of the pick-ups of the orbit measurement system (CODD).

On the blue table a wire scanner, measuring the vertical profile of the beam by sweeping a wire through its path while detecting scattered particles. The detector is a plastic scintillator at the black tip of the vertical metal tube. At the other end of the tube, a photomultiplier converts the light into an electrical signal.
