sPHENIX discussion of the superconducting solenoid

[Kin Yip <kinyip AT bnl.gov>]

Hi,

In Wed.'s meeting (Dec. 21, 2016), a few of us felt that the space between the steel walls seem too "narrow" when we look at the Flux Return base/wall, eg. :

This morning, I went to 912 to measure a few lengths (with a self-retracting "measuring tape") .

In the cross-sectional view as shown in the above picture,

the outer length of solenoid/cryostat is ~ 354 cm ;
the internal length between the two steel walls is roughly ~405 cm ;
and the horizontal length of wedge/bracket is like 76 cm each .

I guess, since the cylindrical cryostat/solenoid "sits" in the middle of wedges, it should be OK.

This was just to make sure and test/measure with my own hand ...


Yours scientifically,

Kin
