Review ASPD Mount

• P4 is the reference target

• Sensor center is at (5,-26,8) wrt P4

Note 3 plates!

One of the plates is 4.6mm, another 10.0, another 12.1

P2 63 mm tall

Here we only have 2 plates: p1=10.0mm p1_bottom_spacer=4.6

p2 is still 63mm andthe target is still 3mm

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 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

How many spacer plates?

At this point, 2

Here the outer plate is a 192 type

Side view

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
