sPHENIX discussion of the superconducting solenoid

[Kin Yip <kinyip AT bnl.gov>]

Dear John,

In the file of "Alignment.....pdf", on p.33 or at the top of p.68 etc.,  you can see that they use micro-epsilon.  Epsilon is the strain ( dl/l ).  You typically see
hundreds of micro-epsilon on p.33.   If I look at our measurements (we're temperature-corrected --- including the gauge factor),
the largest strains are  ~E-4  (10^-4) . 

In these cases, our measurements match with their stuff, at least in the order of magnitudes ( as 100*1E-6 ~ 1E-4 ).
But in later pages, p. 68 etc., for TS07, TS21 and TS91, they have hundreds of thousands micro-epsilon that we don't see (yet) :-)

On p.29-32, I actually noticed the "installation procedure" in its version 0 (compared to Jim's version 2).

Hi John,

The following is the email that I sent almost 2 years ago.

I've copied them to :

/direct/u0b/kinyip

in RCF.  In RCF, all users should be able to see the files.   Each one is 100-200 MB.

The files are :
Alignment, Support Rods, Fields and Forces, Reservoir & Vacuum System.pdf*
Axial Mechanical Position & Tie Rod Strain Gauge Log.pdf*

Hi,

In our Babar server (/bnl.gov/c-adnas/babar), under the directory "Volume 5 DESIGN AND QUALITY CONTROL REPORT",

there are two files :

"Alignment, Support Rods, Fields and Forces, Reservoir & Vacuum System.pdf"

and

"Axial Mechanical Position & Tie Rod Strain Gauge Log.pdf"

which have many strain gauge measurements (and even calculations).    Other files might have some more but these two
should be the main ones , I think.
