• Inner sensor2d is 80.6356.35 121.95
• My Cocoa model uses 135.45 and 127.95
  respectively
• However, there is another drawing of the top and
  bottom ASPD packages where the top is without the
  p1_top_spacer. Bottom4.610, Top12.110
• Both sets are in Calvo's ftp area

Z for ASPD mount, part 1

• From frame to chamber surface is 6.35mm, per
  Oleg. From the picture this must be in the
  negative CMS Z direction
• The plate (192 or 177) is mounted to the frame by
  a 35mm shim (176)
• The plates 192/177 are 6.35mm thick
• ? top of plate (192/177) to surface
• 35 6.35 6.35 47.7mm

Z for ASPD-T mount Part 2

• Height of P2 63mm
• Height of P1 10mm
• Height of P1_spacer 12.1mm
• PG4 target thickness 3mm
• PG4 to bottom of ASPD holder 88.1
• PG4 to PG in plate holding ASPD holder is
  available from photogrammetry ? 83mm
• OK!

CMS-SG-UR-0103

• The theoretical Z of the top of the top (outer)
  ASPD is 7.5mm nearer the IP than the Z of the top
  of the top (outer) ASPD
• The 17-May drawings show a 7.5mm smaller spacer,
  which would make the bottom ASPD farther from the
  IP than the top one
• Agreement
