Montage de l'expérience g-2

The muon storage ring at the end of the South hall, photographed during installation of the electron counters (inside the ring on the far side) and before the shielding roof was put into place. The proton beam from the synchrotron enters the ring tangentially on the side nearest the camera, the entry point being hidden by the boards bridging the gap between the ring and the shielding.
