It is my understanding that each of the permanent magnets will require <br>
one of these correctors. Only two of the three windings per assembly <br>
will likely be powered. Hence the estimate of 400 units and 800 power <br>
supplies. It seems to me better to build all the units with the three <br>
windings and power only two, to simplify fabrication and assembly. And <br>
we might need three in some locations. Rabbet joints assumed in the <br>
steel to simplify assembly.<br>
<br>
I'll send you the opc file for this under separate email.<br>
