FROM THE ASSOCIATE DIRECTOR


This month's excitement flows from three main activities. First, the house was full with x-ray users recording data, and, in the future, you'll hear a report about how x-ray beam position stability has been bumped up another notch by the accelerator operations group testing a new horizontal storage ring orbit correction algorithm based on x-ray beam position monitors with horizontal sensitivity. This is another technical advance following the beamline upgrades to accommodate undulator sources. Second, if you weren't able to attend the Users' Meeting, find some articles highlighting engaging workshops and student paper and poster prize winners. The MacCHESS workshop organized by Tiit Lukk highlighted how fast framing detectors create new science opportunities in time-resolved crystallography and BioSAXS. The XES session organized by Ken Finkelstein discussed science and practical concepts leading into a two-day hands-on workshop offering expert help with simulation and analysis software and 36 hours devoted to measurements using the new Dual Array Valence Emission Spectrometer (DAVES) at the C1 station. And last but certainly not least, read about the antics of more than two-dozen undergraduate research assistants doing research and serving as "science ambassadors" in our outreach and education program. Busy times...
