11. Review ASPD Mount P4 is the reference target Sensor center is at (5,-26,8) wrt P4

13. ASPD(B) Here we only have 2 plates: p1=10.0mm p1_bottom_spacer=4.6 p2 is still 63mm and the target is still 3mm Total height=80.6 PG4

14. ASPD Sensor: P2 PG4 hole Sensor center (p2)

15. Mounting plate 5599C192: Outer or Inner? 6.35mm thick

16. ME+1/2: Claimed to be outer but really inner plate type? Both used

17. ME+1/2 Top Plate

18. ME+1/2 top plate Either way the thickness is 6.35mm and the shim is 35mm

19. Solution: Photograph! Outer here is D177 type

20. PG4 to base of mounting Outer sensor2d is 92.7+35+6.35 = 134.05 Inner sensor2d is 80.6+35+6.35 = 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. Bottom=4.6+10, Top=12.1+10 Both sets are in Calvo's ftp area

21. How many spacer plates? At this point, 2 Here the outer plate is a 192 type

22. Side view

23. 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

27. 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

28. Relative to Surface 88.1mm from PG4 to bottom of ASPD holder (top of mount plate) Mount plate (6.35) + Shim(35) + FrametoSurface(+6.35)  -47.7mm -135.8mm PG4 to surface for Top ASPD -7.5mm = -128.3mm PG4 to surface for Bottom ASPD Mount plate top + MountPlate thickness = DCOPS Dowel = -41.35 Mount plate top + MountPlate thickness + DCOPSDowel to Center = -47.7+6.35+41.27 = - 0.08
