Before locking down the ITM suspensions as part of the new baffle installations, we measured the positions of each test mass and compensation plate (CP) from the outer bevel to the inner cage:
EDIT: clarifying that "left" and "right" here refer to when looking at the face of either the test mass or CP, so left and right flip when going between TM and CP on the same suspension.
ITMY
Compensation Plate -
- Left: 9mm
- Bottom: 24mm
- Right: 8mm
Test Mass -
- Left: 14mm
- Bottom: 22.5mm
- Right: 16mm
ITMX
Compensation Plate -
- Left: 8.5mm
- Bottom: 20.5mm
- Right: 8mm
Test Mass -
- Left: 13mm
- Bottom: 20mm
- Right: 16mm
See attached photots for Anamaria's sketches of nominal positions and how they relate to the baffles.
For reference I got these numbers from the following e-drawing files:
HR cage baffles: DCC D2500081 FULL ASSEMBLY D2500081 A+, SLIC, QUAD SUS CAGE BAFFLE ASSY2.easm
CP cage baffles: DCC D2600035 D2600035 A+ SLIC CP SUS CAGE BAFFLE ASSY-15deg review2.EASM
For the keen eye you'll notice that the CP optic and the tests mass are not at the same height when in reality they should be. Because the CP optic isn't quite well aligned to the cage in this drawing in an IAS sense, it's ok because the baffle IS well aligned to the optic so the relative numbers we would use to align are, well, relative and hold true.
