sPHENIX discussion of the superconducting solenoid

["Craddock, Wesley W." <wwc AT slac.stanford.edu>]

John,
I will attend your meeting this coming Wednesday.  Just a few thoughts and 
questions.  

1) Will you be presenting shipping loads by truck as compared to the original 
C5 delivery?  If they are similar, I would suggest an analysis.

2)  What about your thermal shield axial restraint.  It looks better than, 
the foam blocks that Mike Racine and I installed for moving the solenoid to 
End Station A.  However, the ends look "pointy".  What is the impact of point 
loads on the shield.  I think you should do an analysis to verify that it is 
OK.  Although the shield is thin, it still has some substantial weight.

3) As I mentioned before, I am concerned about the valve control box, 
particularly the heavy current leads.

Talk to you on Weds.

Wes

Subject: Re: Readiness to ship BaBar magnet

Pasquale, Wesley, and Mike,

I have attached some slides from Paul Kovach about the work they've done in 
the Superconducting Magnet Division about shipping the BaBar solenoid to BNL 
which we plan to review this Wednesday, July 30.  Because you three have so 
much experience and history with the solenoid, I would like your input on 
whether the magnet is ready to ship here, and whether there are any 
additional precautions we should take before we set a ship date.  I would ask 
you to plan to summarize your findings, comments, and recommendations either 
collectively or individually in email(s) to me afterward so we could consider 
whether we should take any additional precautions.

BNL is now paying for BlueJeans videoconferencing, which you should be able 
to connect to without any special hardware or software (although you will 
need a decent network connection).  If there are problems with the 
connection, call or message me on skype (johnstonyb) and we'll move to that.  
The meeting is

11am EDT
8am PDT
5pm CEST

and I have the start a little bit earlier in case of connection problems; I 
think the meeting will be about an hour or perhaps a little more.
