- Disabled MCL path in mcdown/mcupscript.
Nominal gain in mcdown/mcup was -50 and -100 respectively.
- Confirmed the stable lock was just because of the quiet seismic of the Friday night.
- Improvement of the PRM ASC servo
RG3.2 (3.2Hz Q=2 Height 30dB)
=>
RG3.2 (3.2Hz Q=10 Height 30dB) + zero[f, 1, .5] pole[f, 2, 3] zero[f, 4.5, .5] pole[f, 3.5, 3]
Filter shape comparison is found in the second plot attached.
The resulting spectra (freerun vs controlled) is found in the first plot.
Nominal PRM ASC gain is +70
- Openloop TF measurement

- REFL55/REFL33 phase adjustment (in lock)
REFL55 phase fine tune (95.25deg) (x1,x0.3)
REFL33 phase (-13.0deg) (x1, x2) |
