- Condition:
-
we assumed that (PR2,) PR3 was aligned.
-
- What is to be done:
- Align the optics with green laser.
- lock Green
-
lock IR
-
Procedure: how to lock the Arm cavity
-
with Green
-
open the Green shutter.
-
check PR3-P/Y by looking at the Tcam at ITMX. check if the incident beam from PR3 (also check the oplev position is not far away from the 'GOOD_POSITIONS') is centered, by eye.
-
Mis-align ITMX in Yaw for an easy alignment of ETMX.
-
Align the ETMX so that the reflected beam spot is centered with Tcam for ITMX.
-
Align the ITMX so that the beam spot is centered with Tcam for ITMX.

- Tips:
- If the alignment is good enough, there is no coupling between the motion and the transmitted light (PD signal).
