WBSC3 ITMx Alignment, Final Number Collection
Putting all the final alignment numbers for ITMx into one log to make it easier to find in the future.
-
X Axis Position: 5012.75 mm
- Target: 5012.95 mm
- Error: -0.2 mm
- Tolerance: ±3.0 mm
-
Y Axis Position: -200.09 mm
- Target: -200.0 mm
- Error: -0.09 mm
- Tolerance: ±1.0 mm
-
Z Axis Position: -83.24 mm
- Target: -83.1 mm
- Error: -0.14 mm
- Tolerance: ±1.0 mm
-
Pitch1: 976 µrad down
- Target: 971 µrad down (619 µrad ITMx pitch + 352 µrad FC correction)
- Error: 5 µrad down
- Tolerance: ±50 µrad
-
Yaw: 23 µrad CCW
- Target: 0 µrad
- Error: 23 µrad CCW
- Tolerance: ±50 µrad
1: We had to tear down our equipment at the X manifold spool for the spool re-install before the ITMx HR First Contact was removed, therefore we will not get a chance to measure the pitch after the FC removal. We have to trust that the calculations in E1200791 are correct and the ITMx pitch will be within ±50 µrad of its 619 µrad down target pitch after the FC is removed.
