SR3 X, Y, Z Position First Look
IAS: J. Oberling
SUS: J. Bartlett, A. Ramirez
Took a first look at the X, Y, and Z positions of the optic. The current position errors are listed below:
-
X axis (lateral): -2.2 mm (south)
- Tolerance: ±3.0 mm
-
Y axis (longitudinal): +4.7 mm (west)
- Tolerance: ±3.0 mm
-
Z axis (vertical): +0.9 mm (high)
- Tolerance: ±3.0 mm
SR3 needs to be pushed to the east to correct the longitudinal error, and if we correct some of the lateral error in the process I won't complain. We will commence with the pushing of the suspension on Monday.
Note, to get here, Jeff, Andres, and a little bit of I, connected up the remaining OSEM connections in and out of vacuum. Jeff and Andres then suspended the masses and verified damping works. They installed the corner cube assembly (with a minor hiccup). Then, I ran quick L, T, and V TFs - all of which looked clean, so the numbers Jason states above are true.
