Edi Dalla Valle from vacuum group replaced the roughing pump TSG:RP1 in the morning. However, the pumping curve showed a leak: see attachment. It was suspected the VCR water line connection between the lid and the base of the target Heat Shield. After venting the chamber found the VCR connection between the lid and the base forgotten finger tight. Tighten it with wrenches and restarted pumping. |

Turned ON the water for the heat shield cooling circuit. Put a lockout padlock on the transformer breaker since Controls work still seems to be underway. |
