sPHENIX discussion of the superconducting solenoid

["Yip, Kin" <kinyip AT bnl.gov>]

Hi,

 

Dan Sullivan just called me and told me that Dan hadn’t finished the connector work (underneath the Doghouse) and he’ll finish it tomorrow. 

Pete Galioto worked very hard but it’s hot, he kind of felt uncomfortable to continue this afternoon.

I spoke to Dan.  Pete needs more time so Dan will contact Len or reply to this email when he is done.  Only one person can work there at a time.

Hi,

 

I’m not sure … Dan has not said that he’s finished.   You can always go there and talk with them.  Why don’t you talk with them ??

All,

 

At 11:56am, someone was on the scaffold at 1008.  Are they complete so we can look at the dog house at 1pm?

Hi,

 

I talked with Leonard’s guy David and he was looking at it today.  David said that he’d come back on Thursday.

 

Dan is doing it today (now) …. Is this clear enough ?

All,

 

As a note, Cryogenics needs to install some temperature sensors that were removed.  We will need some time to do that before MLI wrapping.

 

Do we want a meeting to coordinate timing for tasks?  Len and Rob are on this email for cryogenic electrical.

Hello Ray, Dan and all,

 

I am at 1008 and Ken Ruler and his Cryo colleagues have just finished the leak check for the pressure test (80 psi) successfully (in the Doghouse).  No leak !  ( It seems that they went to 87 psi for 10 minutes and went down to 80 psi for leak check. )

 

Can you please proceed to change the connectors , install the cold-bar (?) ??
