sPHENIX discussion of the superconducting solenoid

[John Haggerty <haggerty AT bnl.gov>]

Hello,

I am not sure everyone is aware of the BaBar web site with some of the 
drawings:

> http://www-project.slac.stanford.edu/slacpix/BaBar/cad_draw/

I emailed a colleague at SLAC for access to more of the drawings.

In the meantime Pasquale answered my query almost immediately, I don't 
think there's any sensitive information in here so I'll post it here:

John,
indeed I have to come to USA in May, for a couple of weeks, but
I have to stay in Fermilab for the test of the prototype module
of Mu2e. I looked to the possibility to come to BNL when coming back
to Italy  but I did not find a satisfactory solution, because I have a very
tight schedule here next months. Unfortunately the test of the prototype
was delayed by a couple of months!  So I think it would be better
to have a (or more)  skype call soon. Next week I am away for some days but
thursday 19 . If you can make a list of items to be
discussed I can look at the documentation in my hand and we
can have a dedicated skype call. Let me know how many folder you
received from SLAC. Some years ago in ASG Superconductors (formerly
Ansaldo Magneti) I found all the folders (10 if I am not wrong) related
to Babar magnet. I hope
they are still there. What are your plans for the magnet assembly and test?
May be I could have later this year a chance for visiting BNL.
The problem of the force is quite important and shall be managed carefully.
Recently when I studied the possibility to move the magnet to Italy
for SuperB I had to look at the magnetic forces because a possible change
in the iron flux return. I am attaching the chapter of SuperB TDR with
my considerations about the magnet (maybe could be useful for you).
So let's try to organise a skype call for next week. I hope I can really
help you
as much as I can.

Best regards
Pasquale
