[Jenne / Kiwamu]
The X green beam has been realigned to compensate the effect of the ETMX repositioning.
After the alignment we became able to lock the 00 mode with the X green beam.
For the alignment:
spot position on the ETMX mirror = within ~ 1 cm. This number is strictly constrained by a homemade aluminum iris that Jamie put last Friday.
spot position on the ITMX mirror = unknown, but looks pretty good on the CCD camera.
spot position on the PSL table = ~ 1 mm downward from what it used to be. The horizontal alignment is perfect.
The X green beam again became a reference of the beam axis.
The ETMX suspension tower is in a good place.
Kiwamu will work on the green alignment over the weekend. Assuming everything works out, we'll try the same procedure on ETMY on Monday.
