The X and Y arms were locked successfully using ALS and the arms could be scanned and held to support IR resonance.

The same procedure as in elog 9219 was followed. In-loop noise was measured to be between 200-300 Hz rms for the lock.

ALS settings for the lock

X arm : FM 2, 3, 5, 6, 7, 8, 10  Gain = 11.0
Y arm : FM 2, 3, 5, 6, 7, 8, 10  Gain = 10.0
