sPHENIX discussion of the superconducting solenoid

[Achim Franz <afranz AT bnl.gov>]

Hi, 

sorry but something didn't seem right and the central field was far too high 
when I checked. With full field and no return yoke we get about 1,2T and I 
was getting 2T, now its 0.4T,  I was off by a factor of 10 in the central 
coils, forgot to change the exponent. 

Here are two plots, B along z at R=0.1m and the 2D plot with the lines for B 
from 50 to 500Gauss. The 50Gauss limit is at about z=7.5m at R=0 and R=8m at 
z=0. 

Please disregard the previous plot.
Sorry about that
Achim
