We report on the study of a storage ring capable of sustaining an electron beam of the quality required for a high-gain free electron laser in the vacuum ultraviolet and X-ray region. We describe a method for the optimization of the design of the storage ring where several competing and often conflicting requirements come into play . We present an example design of a ring that satisfies the req...

The recently implemented top-up operating mode of the Advanced Photon Source (APS) storage ring has motivated an emphasis on nonintercepting imaging diagnostics in the injectors. We present the upgrades to the optical synchrotron radiation (OSR) monitors on the accumulator ring and injector synchrotron as well as the plans for a new OSR monitor on a chicane dipole in the linac and for an optica...

The Muon (g − 2) experiment, E821, at the Brookhaven AGS has the goal to measure the muon anomalous magnetic moment to a relative accuracy of ±3.5 × 10 −7. A su-perferric 14 m diameter storage ring has been constructed and an averaged magnetic field uniformity over the 90 mm diameter muon storage region of ± 1 part per million (ppm) has been achieved. A truncated double-cosine super-conducting ...
