The next ALS shutdown will begin April 15 for installation of the wiggler for protein crystallography. User beamtime is scheduled to resume on May 22. Commissioning of the coupled-bunch longitudinal and transverse feedback systems has progressed very well in the past few months. The ALS now offers scheduled operation with these systems on, but with a few restrictions. As before, the current at 1.9 GeV is limited to 260 mA because of concerns about the power-handling capabilities of the disk window in rf cavity number 1.
