STATE of H1: Planned Engineering & LOCKED
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 10mph Gusts, 6mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.28 μm/s
QUICK SUMMARY:
SQZ_OPO_LR was giving us this error: "CLF frequency out of range, check CLF CMB". I do not recall how this was resolved by Daniel while he was checking out the CMB. Once that was resolved we got the classic: "pump fiber rej power in ham7 high, nominal 35e-3, align fiber pol on sqzt0." issue. The Quarter & Half wave plates on SQZT0 were touched up to minimize H1:SQZ-SHG-FIBR_REJECTED_DC_POWER_MON. OPO was locked. Great!
Then the FC wasn't locking:
So FC2 was moved from its nominal location. only after I accidentally moved ZM1 and reverted it.
Fumbled with the FC2 sliders for a while, then used the clear history button.
Fumbled around some more with the FC2 sliders.
Locked the the FC with FC2 P @ 246.1 Y @ 51.1
And now the SQZ has been SQuoZe.
Forcast for tonight's wind looks good for a stable lock.
