Per WP#12649, the ASCIMC model was updated. Two test points were added to the IMC-WFS_B_{PIT,YAW}_OUT outputs that were then DQed to 16k, see attached screenshot of the new testpoints. These channels are being saved at the higher rate so they can be used as jitter witnesses, see attached screenshot of the channel list. The new channel names are "IMC-WFS_B_{PIT,YAW}_16K_OUT". Erik helped me set up these new test points, and Dave took care of the model and DAQ restart.

Before the model restart, I had checked the ASCIMC model and saw no SDF differences, so I assumed that we were good to go to restart the model. Here are two errors I made:

• the IMC WFS should be offloaded before this, and the resulting PZT offset should be SDFed
• the IMC should be taken offline, so the restart doesn't kick the suspensions

Once the restart had happened, and SDF reverted, the IMC came back very poorly aligned. Jeff and Tony had to move the IMC PZT offset by "hundreds of counts" to get us back to a good enough alignment to lock. After that, Jeff, Tony, and I proceeded to engage the IMC WFS, and turned up the WFS gain to 0.5 to help the loops converge faster. Once they converged, we took the IMC guardian to "MCWFS offloaded". Here, we made another mistake by forgetting to accept the PZT offsets in SDF, so when ISC_LOCK went through the "SDF revert" state, the offsets were set to some old value, which put the IMC back in a bad alignment. We repeated the process again, and this time remembered to save the new offsets in the SDF. I have attached a screenshot of this change.

Per WP12651 we investigated and replaced the IO Chassis supply for H1SEI23 which supports seismic on HAM 2 & 3.  This supply is located in Mezanine rack C3, location U2 Right Side, provides +24V, and measured ~3.5A draw.  The fan was chirping and grinding which suggests a failing fan bearing.

Old Supply = S1202002 old fan worn out bearing to be refurbished.
New Supply = S1201919 new fan with ball bearing.

ECR E2400330

Calling this out explicitly: 
    We have changed the OSEM PD satellite amplifiers on H1SUSPRM, H1SUSPR3, H1SUSBS, H1SUSSR3, and H1SUSSRM top masses; see LHO:85463
    We chose to implement ECR E2400330 by modifying spare chassis ahead of time, and installing those modified spares in place of the old chassis (which will become some other suspensions' "new" amps next week).
    Though the ECR only changes the whitening stage frequency response.
    However, because the old vs. new chasses have different set of other overall transimpedance gain determining components, the read-back for the OSEM PDs will likely change slightly.
    Thus, the OSEMs' recast as EULER basis signals will also change slightly, *looking* like an alignment change, even though the alignment of the physical suspension will NOT have changed.
    This won't be in any consistent direction, and the transimpedance gain is determined by components that have value at any value within the components' tolerance.

I attach two examples, H1SUSPR3 and H1SUSBS, of the levels we're talking about -- In the OSEM basis, it's 1-3 [urad], and same in the EULER basis. For the beam splitter, a physical change in alignment of that magnitude would be significant, hence me bringing it up explicitly.

So, the new normal for the following suspension alignment starts on 2025-07-01 12:30 UTC:
    H1SUSPRM
    H1SUSPR3
    H1SUSBS
    H1SUSSR3
    H1SUSSRM
We'll definitely have to re-run initial alignment after today's maintenance day, given that (unrelated)
    - we rebooted the entire electronics racks at EY to replace failing power supplies,
    - we rebooted the seih23
    - we adjusted the green camera alignment

We noticed a failed drive on h1daqfw1.  As we were in maintenance we powered down the system and removed the disk.  This was a 1TB spinning disk.  It was most likely put in to allow us to have large storage if we needed to write frames locally and then move then over the network, this was a very real posibility at point.  However we never ended up doing that.

The system was taken down at around 13:38 local time.

Per WP#12646, Fil and I went out to the floor and realigned the ITMX green camera, as Sheila noted it was poorly aligned in alog 84819. (Before we began, Corey transitioned the LVEA to laser hazard per WP#12647).

Before going out to align, I locked the X arm in green only using the camera offsets for the alignment. I offloaded this X arm alignment, so it could be preserved once we moved the camera.

With the X arm still locked, Fil and I connected a computer to the green camera output, which gave us a faster, live view of the camera as we adjusted it. Fil used a Rainbow controller to zoom out very far to reduce our chances of moving the beam too much and losing it. Fil then removed the camera housing cover, and adjusted the nobs on the camera. As he adjusted in the desired direction, I zoomed the camera in slowly, to ensure that we were moving the beam closer to center. We iterated this process several times. The first time Fil went to put the camera cover back on, we noticed that the action of placing the cover bumped the aligment a little bit, so we had to overcorrect in the opposite direction slightly so that the beam stayed centered as Fil replaced the cover. I then tried adjusted the zoom and lens slightly, and decided that the image was well-centered enough to finish the work.

Once we were back in the control room, I updated the camera offsets. I have attached the SDF of these new offsets.

We took open loop transfer functions for some suspensions today. Some were taken so we have 'before' OLG and loop suppression data before we switch out their satamps (ITMX, ITMY), and the rest were after the satamps were switched out (85463) so that we could confirm that they all looked good (PRM, PR3, SRM, SR3).

0.4:10 (old) satamp OLG TFs
ITMX M0
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, L2->R0 damping off, etc
- We needed to adjust the excitation filters for V and Y, plus lower the amplitude by a factor of at least 5x to keep the suspension dac from overflowing and saturating. These excitation filters were originally matches to the ETM ones, but we had to adjust them.
Data: 2025-07-01_1645_H1SUSITMX_M0_WhiteNoise_{L,T,V,R,P,Y}_0p01to50Hz_OpenLoopGainTF.xml r12366

ITMY M0
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, L2->R0 damping off, etc
- We needed to adjust the excitation filters for V and Y, plus lower the amplitude by a factor of at least 5x to keep the suspension dac from overflowing and saturating. These excitation filters were originally matches to the ETM ones, but we had to adjust them.
- When trying take Y, there was noise affecting mainly F1/F2/F3 (ndscope1, ndscope2) that was happening every ~4mins. Every time it happened it would cause overflows as well. This made it really hard to get a Y measurement, so the Y here looks pretty bad. We can try another time to get the data for Y. We don't know why this was happening but it stopped once we left HEALTH_CHECK (but it didn't start when we first entered HEALTH_CHECK)

0.1:5 (new) satamp OLG TFs
Note: for all of the following measurements, the OSEMINF FM1 filter had been updated from 10.4:0.38 to 5.31:0.0969 to match the new 0.0969:5.31 satamp (85471)
PRM M1
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, etc
- We needed to increase the exc gain to match the decrease in damping loop gain (-0.5)

PR3 M1
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, etc
- We found that some dofs were being very underdriven, so we upped the gain by 10 or 100x

SR3 M1
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, etc
- We found that some dofs were being very underdriven, so we upped the gain by 10 or 100x

Main takeaways:
    - ITMY Y was bad due to some strange mystery noise and needs to be retaken
    - PRM, PR3, SRM, SR3 all had new satamps and updated OSEMINF FM1 filters to match
    - SRM measurements were taken with optic align offsets ON

To finish off Fil's work for ECR E2400330 replacing the M1 satamps for BS, PRM, PR3, SRM, and SR3, I replaced FM1 in their OSEMINF filter banks from being z:p = 10:0.4 to z:p = 5.31:0.0969 to properly compensate for the new satamp. I've attached the filter file diffs for each suspension. They've all been loaded in.

The new EX purge air compressor and drying skid were turned on this morning at ~8am and dewpoint and particulate measurements were taken at ~11:30am.  See attached pics of the dewpoint monitor at the exhaust of the drying tower, dewpoint at the coupling fitting at the EX spool just upstream of BSC9, and particulate counts at the same spool coupling.  FTIR sample was taken of the coupling fitting and will be stored onsite.

Per WP12650 we investigated and replaced two supplies with locked up cooling fans at EY.  These supplies service power to the field rack R1 and by extension, the neighboring SUS rack.

We noted the -18V supply in slot U26 on VDC-C1 was running very hot, and when we looked the fan was visibly siezed up.  Continuing down the rack, U22 +24V was also siezed up.  We replaced both failed supplies with refurbished supplies with upgraded fans.  We also lubricated the opposing supplies' fan shafts, +18V and -24V respectively with a drop of lubricant each.

U26L S1203041 +18V was lubricated.
U26R S1201988 -18V was replaced.
U22L S1201929 +24V was replaced.
U22R S1300297 -24V was lubracted.

ALOG: 84928.

"Remove the cabling described in https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=84928 from h1brsey and the network switch. Use the video port on h1brsey currently occupied by that cabling to connect to the kvm in the rack instead. Jim noted that "It might have been some sort of kvm or display extension set up Carlos tried for me. The rdp for beckhoff had too much lag to rebalance the BRS, so we had looked at some more direct remote display options, but I don't remember the details." and "the remote adjuster just installed means we don't need it, if that is what it is." Work to be done during any target of opportunity."

This work has been completed.

"Install git and clone the vacuum repos on the vacuum machines where it has not yet been done. Update the scripts used to copy the channel lists from each of the Beckhoff vacuum machines to CDS to additionally copy the EPICS database files. Run the scripts on each of the vacuum machines. No expected downtime or impacts."

I have completed the work on h0vaclx, h0vacly and h0vacmr and copied the auto generated EPICS IOC database files over. These did not need git to be installed. I did not do the remaining machines since I do not believe they are running out of the git repos and I was getting nervous.

A couple of small issues. On h0vaclx I accidentally committed the change to the copy script before pulling changes from the remote repo. On h0vacmr more changes came down in the pull from the remote repo than I was expecting.

I'm followed the pydarm deployment instructions here, to update the LHO pydarm install.

This is the 20250701.0 tag for pydarm, which includes a bug fix for uncertainty budget generation for C01.

This is not the default cds conda environment, but the default you get when typing pydarm at a command line, or specifically invoking by running "conda activate /ligo/groups/cal/conda/pydarm".

We're on a campaign to complete the collection of up-to-date top mass open loop gain TFs for the damping loops (see inventory prior to today in LHO:85289). The QUAD main M0 chain had never been measured, and thus had no tuned-excitation templates to start from, but the ETMY reaction R0 chain had been, and the drive chains and plant are quite similar. So, I've copied over the ETMY R0 templates for the Open Loop Gain TFs and renamed, and ran a "sed -i" to change them to ETMX R0 templates, and hit "go." It worked! Some minor adjustments were needed; e.g. some DOFs needed their gain reduced, and a few resonant gain filters Q reduced.

Here's the set of measured new templates committed to the svn in the following location. 

Since the excitation depends on the damping filters installed, I attach a screenshot of the damping loop MEDM screen during the measurement.

I'll make comments about the *results* of the measurement in a separate aLOG.

Tue Jul 01 10:12:41 2025 INFO: Fill completed in 12min 37secs

This morning, while waiting for Maintenance, noticed that after the In-Lock SUS Measurement, we did not "automatically" return to Observing (which would only be a few min due imminent Maintenance).  Turns out there was an ITMx SDF Diff for (H1:SUS-ITMX_L3_LOCK_L_TRAMP, see attached). 

Since it was starting to get hectic in here leading up to Maintenance, I did not do anything about this SDF and kept H1 out of Observing.

The FSS RefCav TPD has been falling, so this morning I tweaked the beam alignment into it from the Control Room.  With the IMC off the TPD was ~0.745 V, and after the alignment tweak the TPD was ~0.813 V (see attached plot).  I also attached a screeshot of the PSL Quad Display after the alignment tweak.  Corey relocked the IMC, and with the IMC locked the RefCav TPD is ~0.810 V (it's normal for there to be a slight difference in RefCav TPD with the IMC locked and unlocked).

This TPD is not as high as Ryan was able to get on June 11th, when this was last done.  Further, the RefCav Refl spot is different from that time as well (lower left image on the Quad Display picture).  This likely means things on the table are moving, which tends to happen when the weather changes.  The TPD is looking good for now, but we will continue to monitor this over the coming weeks; an on-table FSS beam alignment may be necessary in the near future, depending on how things change.

Ivey and Edgard,

We just finshed a fit of the Yaw-to-Yaw transfer functions for the OSEM estimator using the measurements that Oli took for SR3 last Tuesday [see LHO: 85288].

The fits were added to the Sus SVN and live inside '~/SusSVN/sus/trunk/HLTS/Common/FilterDesign/Estimator/fits_H1SR3_2025-06-30.mat' . They are already calibrated to work on the filter banks for the estimator and can be installed using 'make_SR3_yaw_model.m', which lives in the same folder [for reference, see LHO: 84041, where Oli got the fits running for a test].

Attached below are two pictures of the fits we made for the estimator.

The first attachment shows the Suspoint Y to M1 DAMP Y fit. We made sure to fit the asymptotic behavior as well as we could, which ends up being 0.95x10^{-3} um/nm (5% lower than expected from the OSEM calibration). The zpk for this fit is

    'zpk([-0.024+20.407i,-0.024-20.407i,-0.044+11.493i,-0.044-11.493i,0,0],[-0.067+21.278i,-0.067-21.278i,-0.095+14.443i,-0.095-14.443i,-0.07+6.405i,-0.07-6.405i],-0.001)'

The second attachment shows the M1 drive Y to M1 DAMP Y fit. We kept the same poles that we had for the other fit, but manually fit the zeros and gain to make a good match. The zpk for this fit is

'zpk([-0.051+8.326i,-0.051-8.326i,-0.011+19.259i,-0.011-19.259i],[-0.067+21.278i,-0.067-21.278i,-0.095+14.443i,-0.095-14.443i,-0.07+6.405i,-0.07-6.405i],12.096)'

Hopefully Oli and co. will have time to test this soon!

I went down to end Y to retrieve the usb stick that I remotely copied the c:\slowcontrols directory on h1brsey to, and also to try to connect h1brsey to the kvm switch in the rack. I eventually realized that what I thought was a vga port on the back of h1brsey was probably not, and instead I found this odd seeming wiring connected from what I am guessing is a hdmi or dvi port on the back of h1brsey, to some kind of converter device, then to a usb port on a network switch. I'm not sure what this is about, so I am attaching pictures.
