sPHENIX discussion of the superconducting solenoid

[EdwardOBrien <eobrien AT bnl.gov>]

    Hi Kin,
     Thanks for the pictures. I also heard that the cryo guys believe that they
    have found the problem with the cryo plant and are working  on fixing
    it. I understand that they think it is grease or oil contamination from an
    o-ring. Do you know anything more about this?

Hi,

 

I’ve attached a zip file of 3 photos here:

https://collab.external.bnl.gov/sites/sPHENIX-Magnet/Pictures/High%20Field%20Test/2017-11-2.zip

 

One of the pictures shows you that all the roof steels have been installed.  Jon Hock told me that his guys still need to do a little work before he’ll call PHENIX people to

install the magnet probes before he closes the end-walls.  

 

In the above zip files, I include two other pictures of MCM cables and space blocks (by Frank Toldo et. al.) taken by PK Feng and he calls them

 “work of art” !  ( Well, he’s got “a little” to do with it. )    Frank is preparing for connecting the MCM cables with the terminals ….

 

At the same time, Zeynep Altinbas and Carl Schultheiss are testing their rack on the 3^rd floor of 911.  I put their test steps (from Carl) and the report (from Zeynep)

on the item of Oct.31 and Nov. 1 :   https://collab.external.bnl.gov/sites/sPHENIX-Magnet/Lists/Calendar/DispForm.aspx?ID=148

 

( If I get more report(s), I’ll continue uploading into the calendar :  https://collab.external.bnl.gov/sites/sPHENIX-Magnet/Lists/Calendar/calendar.aspx )

 

The Cryo group continues to install their pipes/connections … Richard Meier and his colleagues are making their Cryo connections.

 

I’m also urging Pablo Rosas to do his test(s) (of interlocks etc.) as soon as possible……

 

Kin
