Wednesday, August 13, 2014, 08:31: Starting cool down as flow rate on HS + MSP is low. A low flow trip of the TGHT should be avoided.
Wednesday, August 13, 2014, 11:54 : Curtis Ballard contacted me and asked if they could valve off the Cu-LCW circuit to the Test Stand. Heaters had been previously brought down. Bias off and power supplies are switched off. IV4 closed.
Wednesday, August 13, 2014, 12:00: Cooling water syupply valved off to Test Stand.
Flow rates are back to normal since yesterday evening
