[Hallc_running] [New Logentry] RC daily update

We are currently in Restricted Access. We had a sudden loss of LCW to Hall C which shut down all HMS magnets and SHMS HB. The water hose in the new HMS Q2 power supply popped off and subsequently generated a waterfall from the top of the HMS carriage to the floor. We shut off the water to the HMS Q2, but the LCW system for all the halls is currently being purged and filled and is expected to return in a few hours (noon-ish). In the meantime, floor has been mostly dried out by the HMS, fans are on the HMS Q1 power supply which had some water on its boards. The magnets appear to be fine, but we need to check out the HMS Q1 power supply. Once LCW is restored, Steve and Jack will check out the magnet power supplies to determine if we can run with them. The plan will be to proceed with J/Psi run plan. Preliminary estimate is that we will be locking up at or by the end of the Day Shift. 

Prior to the waterfall, beam was running on J/Psi production #1-1 LH2 setting at 45uA.
