A plane grating monochromator (PGM) has recently been completed and installed on an undulator port at the Synchrotron Radiation Center (SRC). The beamline is designed to be a high resolution, high throughput beamline with an energy range of 8 to 245 eV. Initial results show the undulator is performing very well and agreeing closely with theoretical predictions. The undulator and monochromator can be scanned together throughout the energy range using software on the beamline computer. Undulator scans are routinely performed during the morning shift and the small effects this induces on the storage ring are being further minimized. Monochromator scanning is achieved by rotating the plane mirror and rotating and translating the grating. An advanced control system maintains sub-arcsecond resolution for the rotations. Flux and resolution tests have shown that the grating performs poorly. A new laminar profile grating will be installed soon.
