sPHENIX discussion of the superconducting solenoid

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

Hi,

In our sPHENIX Magnet site, I've a pointer to the old BaBar drawings (as John 
pointed to us).  But that address
stopped working a while ago.  Charles Young has helped to ask the folks who 
know about this to restore the files
and now they're :

http://www.slac.stanford.edu/BFROOT/www/Detector/cad_draw/solenoid/
(or http://www.slac.stanford.edu/BFROOT/www/Detector/cad_draw/ for more stuff)

After this lesson, I've just written a script to download all the CAD 
drawings there to our Babar server :

\\bnl.gov\c-adnas\cad_draw

But from the dates/revisions on the bottom-right corner, those CAD drawings 
are not as updated as those as-built PDF 
drawing

in

\\bnl.gov\c-adnas\Volume 6 AS BUILT DRAWINGS

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
