by vacuum group. The pump was making more noise than usual.

 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.

Mico replaced the T's with copper tube and leak checked.

To recover performance

No supply of N through the piping due to work on the N tanks. Confirmed with Geoff Hodgson. ISIS supply is shut off. Using a bottle until the supply is returned.

Monday, January 11, 2016

Nitrogen supply from ISIS restored and reconnected.

The new controller (XGS-600) installed for IG6 use a different voltage to pressure conversion than the previous models. This causes a discrepancy between values in EPICS and the value displayed on the controller. An e-fault has been submitted.

Friday, December 18, 2015, 14:40: EPICS updated and restarted.

 The Swagelok fitting on the return side of the flow sensor for the HS circuit was tightened to stop the leak. See e-fault 8650

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.
