To try to help, the FFA permanent magnets won't have a power requirement, but the Panofsky Quads that will be mounted along with them will. Based on the latest Magnet count sheet, there will be 50 of them per ARC (East/West) and reviewing Jay's technical write
up, they should need 900W per magnet. He did mention that each would require two power supplies. </div>

With regards to the counts though, there is some discrepancy. Jay, for each of the ARCs, is the number 50 or 100? Looking at your paper, vs the magnet count sheet, you are specifying 100 per ARC vs. the 50. Also, do my assumptions on power and power supply
requirements line up with your specification? </div>

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>
