  Bob,

  please find two files attached (solenoid schematics and overall
BeAST detector 3D picture).

  The gray volume (cryostat) is defined by the following 4 sections
(all values in mm):

   z     r1     r2

 -1830  1640   1850
 -1610  1370   1850
  1610  1370   1850
  2000  1680   1850

  In a similar way, the return yoke (blue volume) is defined by:

   z     r1     r2

 -2500  2700   3000
 -1200  2000   3000
  1200  2000   3000
  2500  2700   3000

  Red volumes are coils. I can give you locations, sections and
current densities if needed. The configuration was optimized in
a way to 1) be compact, 2) provide more or less homogeneous field
in the TPC volume, 3) provide specific field line configuration
inside the gaseous RICH volume in order to minimize Cerenkov ring
distortions.

  We roughly checked with Brett at that time (a year ago) that there
was no major screw up on my side with the basic design parameters.

  Best regards,
    Alexander.
