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

ASPD(T) PG4 Note 3 plates! One of the plates is 4.6mm, another 10.0, another p1_bottom_spacer 12.1 p1_top_spacer 10.0 p1 P2 63 mm tall PG target 3mm thick Total 92.7mm target to base CMS_AL_+ME12_D2_t_b_3D_piezas.dwg

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

ASPD Sensor: P2 PG4 hole Sensor center (p2)

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

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

ME+1/2 Top Plate

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

Solution: Photograph! Outer here is D177 type

PG4 to base of mounting Outer sensor2d is = Inner sensor2d is = My Cocoa model uses and 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= Both sets are in Calvo's ftp area

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

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 = = +47.7mm

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
