[Primex] CLAS Bore approximation for background study

[David Kashy]

Hi Ashot,
The hardware of the CLAS bore for your study can probably be reduced to 
a simple cylinder.

It would start at 36 inches down stream of nominal CLAS center and end 
at 96" from the same point.
The inside diameter can be modeled as 3.06" and the OD as 12". The most 
upstream end and inside of this cylinder is lead about 3/4" thick. I 
would guess you can model the entire thin as lead and the result would 
be reasonable.

If you want a more detail model let me know.
Thanks
Dave
