GOAL of this month

to stabilize the arm displacement using the green beat note

Action Items

Indicators
attachment:green.png complete	attachment:orange.png intermediate state	attachment:red.png nothing happened	attachment:black.png gave up

Step 1. X arm alignment for IR
action	description	status	notes
setup DC_PD at an available port	to find a fringe	attachment:green.png	put Thorlabs PDA255 at AS
align BS, ITMX and ETMX		attachment:green.png
place TRANS_MON_PD		attachment:red.png
make a simple mod/demod system	to lock the IR	attachment:red.png
feeding back the signal to MCL	to lock the IR	attachment:red.png
A2L for IR	for precise alignment	attachment:red.png

Step 2. Re-alignment of green
action	description	status	notes
change beam axis		attachment:red.png	need a helper
rearrange the optical setup at X end	if necessary	attachment:red.png
lock the green to X arm		attachment:red.png
overlap the axis to the IR	using A2L	attachment:red.png

Step 3. Beat note detection
action	description	status	notes
finalize the setup at PSL table	Electronics, cables and etc.,..	attachment:red.png
alignment of optics at PSL table		attachment:red.png
temperature tuning of the lasers		attachment:red.png	need a helper

Step 4. Digital control to stabilize X arm
action	description	status	notes
