Current Status of the Synchrotron Radiation Center

The Synchrotron Radiation Center (SRC) operates the Aladdin electron storage ring at energies of 800 MeV or 1 GeV in support of a broad range of national and international research programs. A low emittance configuration is in routine operation during 800‐MeV shifts and offers improved photon flux density with about the same beam lifetime. An improved undulator compensation algorithm and new optical beam position monitors have been implemented improving beam stability and maintaining vertical beam size variations to < 2% peak‐to‐peak during undulator scanning. Instrumentation initiatives include construction of a modified Wadsworth beamline (7.8 – 50 eV) and a variable‐line‐spacing plane‐grating monochromator (VLS‐PGM, 75 – 2000 eV) to utilize radiation from a permanent magnet undulator. The Wadsworth beamline is being commissioned for photoelectron spectroscopy (PES) experiments using high‐resolution Scienta analyzers. The VLS‐PGM is being constructed for experiments that require higher photon energies a...
