The pump failed to pump down below 2 Torr. on Friday 15th E-fault 8680 submitted. Vacuum group will replace the pump today
|
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.
|
Turned ON the TGHT and ramping it up at a rate of 1A/30sec. Currently it's at 108A. |
