Utilizing the buddy system, (R. McCarthy) I walked the site today and found no immediate issues. The first half of x2 is a barely passable but am working with VAC to determine the next delivery location. To that end, all CP access points are largely unobstructed. The wind fence shows no additional damage at EY, and EX is still intact. FAC systems are operating normally. Large heat load spaces felt cool, no doors were found ajar and the water system is behaving normally (presently full @ ~66.5"). VEA's were all business as usual. 

During the visit I noted a magmeter flow value of 1010675 which should serve as a useful metric in determining any leak/bleeding of the potable system. While at the water room, domestic supply pressure appeared to be holding well. A follow up on the morning of 1/5 will be performed to understand usage over the break while little to no demand is applied.

STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: A fittingly quiet day today. HAM7 alignment work wrapped up this morning, so I transitioned the LVEA to Upgrade Phase Laser SAFE for the break. The stair move from EY has been postponed to the new year due to high tumbleweed interference. Control room workstations (with the exception of operator and VAC stations) and wall FOMs (with the exception of CDS, VAC, and temperature monitors) have all been shut down.

SHIFT SUMMARY: Busy afternoon! We changed plans a bit after we remembered that the HAM7 crew needed the IMC locked for their scattered light investigation, so work in HAM1 and the PSL to prep for JAC installation was put on pause. Locking the IMC went fairly smoothly; MC1, MC3, and the IMC PZT were moved back into alignment based on top-mass OSEMs from when the IMC was last locked, and once the light pipe was reopened, the IMC locked without issue. Input power was brought up to 10W at the HAM7 team's request. Scattered light work in HAM7 will continue tomorrow, but for tonight we've shut the PSL light pipe and lowered input power back down to 1W since chambers are open.

SHIFT SUMMARY:

IFO is in IDLE for Planned Engineering

TLDR - Last few big remaining lock health checks were successfully done.

First, initial alignment was ran successfully and automatically. 

We then started our day with 5 lock steps we wanted to confirm as working in the case that we could not fully lock:

• ISS Second Loop
  • Confirmed working by misaligning PRM and taking LASER_POWER to 62W and then closing the ISS Second Loop. Ryan S and I did this successfully.
• Lownoise ESD Transition
• Lownnoise Coil Driver States
• OMC_Whitening
• Laser Noise Suppression

To get around SRC1 P/Y instability, that would take time we don't have to fix, we locked while manually touching SRM at different times, notably: DRMI_LOCKED_CHECK_ASC, PREP_ASC_FOR_FULL_IFO, MOVE_SPOTS. However, after not being able to get past MOVE_SPOTS - couldn't keep RFPOP90 low enough with SRM touches, we tried a different method to get over the remaining checks suggested by Jenne:

1. Stop at 25W, touch SRM (counts on H1:LSC-POPAIR_B_RF90_I_NORM_MON good if under 12)
2. Manual to Lownoise Coil Drivers - Successful.
3. Auto until LOWNOISE_ESD_ETMX - Successful.
4. Manual to OMC Whitening, damp violins - Successful. Tony Damped violins.
5. Manual to Laser Noise Suppression - Mostly successful - Ryan S took care of this with advice from Keita about the scaling of the IMC_REFL and LSC_REFL IN1/2 and Fast Gain Servo Gains.

For a very comprehensive summary of locking progress, check out Ryan S's Wonderful Alog 88498.

Lock Acquisitions:

1. Lockloss due to SRC1 P/Y at Prep_ASC_FOR_FULL_IFO. SRM railed prior.
2. Lockloss due to Technical Cleaning at HAM2. HAM2 WD Tripped. Cleaning stopped after this.
3. Lockloss due to failed SRM adaptation (with ops acting as SRC1) at MOVE_SPOTS
4. Lockloss at Laser Noise Suppression upon activation of IMC_REFL Fast Gain at 25W
5. Lockloss at Laser Noise Suppression upon activation of IMC_REFL Fast Gain at 25W - though this time we confirmed it was likely the fast gain since Keita and Ryan S stepped through the state with gains scaled to 25W.

Meanwhile,

• Technical cleaning was started at HAM1/HAM2 (but unknown if completed since after a WD trip, they stopped due to locking).
• HAM1 Cleanroom was turned on and prepped for Monday Vent (alog 88501)
• GV5 and 7 Hard-closed (alog 88499)
• HAM7 HV Turned off (alog 88497)
• HAM7 OPO work is way underway, with OPO in but not fully installed.

I powered on the HAM1 cleanroom at ~3:10 PST in prep for next week's HAM1 vent.

SHIFT SUMMARY:

After CDS & H1-Locking work of yesterday, today we transitioned to starting prep work for the upcoming vent of HAM7.

However, there was more CDS work today which was related to ISC Slow Controls....but in the middle of this...

There was a 90min power outage on site!!
