Dear Jim,

    The first step is to redo the tagger optics calculation to determine the 
tagger focal plane position. Once the tagger optics is finalized, the second 
step is to make (and optimize) the magnet design by using the pole profile 
defined by the tagger optics calculation.  The third step is to modify the 
vacuum chamber design. The final step is to make the engineering drawings.

Cheers

Yang
