Source pulled down for Mg removal and cleanup. Done. Supernanogan refurbishing of MCIS optics complete, plus a comple of other items. Opened joints leackchecked and okay. MCISIOC was in a partial state, where devices worked but not interlocks. It turns out that Controls knows about this. Msg to investigate in the morning. Meanwhile, MWS is up with a 16O1+ beam on FC6 presently. FYI, the vacuum pumpdown curve during leakcheck and startup operations.
