[FFA_CEBAF_Collab] FFA corrector concept

[Jay Benesch]

Chase,

It is my understanding that each of the permanent magnets will require 
one of these correctors.  Only two of the three windings per assembly 
will likely be powered.  Hence the estimate of 400 units and 800 power 
supplies.  It seems to me better to build all the units with the three 
windings and power only two, to simplify fabrication and assembly.  And 
we might need three in some locations. Rabbet joints assumed in the 
steel to simplify assembly.

I'll send you the opc file for this under separate email.
