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.

 It seems the exhaust line is blocked which caused pressure to build up and eventually forced the exhaust tube off RP2 as RP1 was roughing down the vacuum chamber.

Vacuum group has been notified and will ask plant group to investigate.

Plant group has removed the blockage. Exhaust lines are reconnected to the roughing pumps.

Will went chamber to replace the filament.
