Went down to Hall A's alcove this morning and walked the area
where the Water Damage repair work is going to happen. After
talking with Neil Wilson and Steve Suhring yesterday along with
the safety prework walk this morning, I find I do not need to
disconnect any bpm electronics in Hall A for the Water Damage
Repair work. All my bpm hardware and beam line bpm cans are
well out of the work area. Closing this atlis.

Finally A5 and A6 appertures have been installed in UITF. I have been waiting some time so that I could connect the current readback wires to these devices. The Picoameters where installed over 8 months ago with Controlled Screens and software support provided by Sue Witherspoon. Current Readback wires connected first thing this morning to A5 and A6 appertures. Beam On!!
