FPMI locked |
|
|
[Yuta, Manasa]
FPMI locked.
Alignment and lock acquisition
1. Use ITMY/ETMY to maximize green transmission in Y arm (to get closer to arm alignment).
2. Use TT1/TT2 to align arms to IR to the Y-arm (Maximum TRY = 0.84)
3. Use BS/ITMX/ETMX to align IR to the X-arm.
4. Use POY11_I and POX11_I to lock Yarm and Xarm.
5. Use ASDC to lock MI.
Modified
1. X-arm trans camera settings changed.
2. Blocked stray green from reaching TRX PD and camera.
P.S. TRX seems to be moving less on the camera because of the oplevs centered and working from last night.
Plan
Lock green to X arm.
