sPHENIX discussion of the superconducting solenoid

["Makdisi, Yousef I" <makdisi AT bnl.gov>]

Nice. Good luck with the walkthrough and hopefully cooldown start soon.

Thanks a lot, Paul !   Nice pictures … Even the floor seems cleaner than a couple hours ago when I was there J

Here are some photos of the pre-walkthrough condition taken an hour ago.

 

Kin,

 

Defective Strain Gauges:

1. TS03 (bad pin M on connector plug J4
2. TS82 (bad connector pin j on connector plug J5)
3. TS32 and TS92 (likely bad connections on Valve Box J6)
4. TS80 (likely shorted at sensor itself)

 

Tie Rod temperature sensors TT01, TT02, TT03, TT04, TT05 are now wired into the Magnet Power Control & Data Acquisition Rack (not Cryo Rack).

 

All Power & Control Racks inspected (EEI) and bar code stickers attached.

 

Regards,

 

Paul

Just to remind you of our meeting tomorrow (Wed.) Jan. 27 at 1:30 pm in the 902 conference room.

 

--- The roughing pump has been turned on since yesterday late afternoon/evening.    I saw Paul Orfin and his guys as well as

Rich Meier are making the final connections.

 

--- Paul Giannotti claimed that he’s just needed another hour.

 

--- I’m looking for D. Phillips to put his barrier for the power lead (on the platform), put up the startle sign and anchor things properly.
