Entry  Thursday, October 04, 2012, 11:06, David Wang, Conditioning Station, Repair, , , Replace conditioning station scroll pump in target hall 

Grant and I replaced the conditioning station broken  srcoll pump with a refurbished scroll pump which is supplied by vacuum group. The replaced pump is bagged and waiting for RPG further survey in target hall . The target hall is survey after the job, and everything is fine.

Entry  Tuesday, October 09, 2012, 14:53, Bevan Moss, Conditioning Station, Development, TM4, UCx#5, Module Move 

TM4 was remote moved from the SCH to the TCS today. This was the first time the module was moved with the framework for the cage in place. The ion gauge on the service cap is closer to the cage than anticipated and as a result the pins for the gauge were sheared off. Discussion as to how to repair the gauge (both short term and long term needs to be had). We will try and rough down the TM tonight, it is not believed the vacuum will be affected.

Entry  Tuesday, October 16, 2012, 07:14, David Wang, Conditioning Station, Standard Operation, TM4, UCX#5, TM4 heat shield helium pressure test and electrical check at CS

Entry  Friday, January 18, 2013, 16:56, Grant Minor, Conditioning Station, Standard Operation, TM4, , VAT valve btwn roughing and nuc. vent. closed 

Bevan attempted to start pumping down on TM4 today remotely but there was an issue.  He will report on Monday.

I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:

- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise)

- Closed the VAT valve between the scroll pump and the nuclear ventilation
