Beam Optics Design on a New Injection Scheme for the University of Maryland Electron Ring (umer)∗

∗ Research supported by the U.S. Department of Energy. † [email protected] Abstract A new optics design for beam injection into the University of Maryland Electron Ring (UMER) is proposed for multi-turn operations. We review the previous method where two pulsed and physically overlapped Panofsky quadrupoles (one is centered on the injector and the other is centered on the ring) are employed. Th...
