We aligned the Y and Z (lateral and vertical, repsectively) positions and Yaw of the ETMx this morning via HEPI adjustments (position coordinates are local to End X):
-
Y axis position: -199.93 mm
-
Target: -200.0 mm
-
Error: +0.07 mm
-
Tolerance: ±1.0 mm
-
Z axis position: -79.97 mm
-
Target: -80.0 mm
-
Error: +0.03 mm
-
Tolerance: ±1.0 mm
-
Yaw: 6 µrad CCW
-
Target: 0 µrad
-
Error: 6 µrad
-
Tolerance: ±10 µrad
The final dial indicator values for those values.
(Corner 4 X value is so different because I was reading the dial indicator differently, it didn't actually change that much.)
Greg and I also did a quick measurement of the level after alignment. I didn't try to calculate a height, but the table is level to within .010" over the span of the optical table, with 3 of 4 corners being more like .005" difference. This agrees with the spec used for the test stands, so I assume this is good enough.
