Workstations updated and rebooted.  This was an OS packages updated.  Conda packages were not updated.

Today's activities:

• Feedthru installation on HAM1 was completed.  An electrical issue with one of the 25-pin feedthrus on the D1 5-way cross and/or in-vac cable means this port will be revisited after ISI installation.  Electrical testing is ongoing for the new feedthrus/cables.
• BSC8 annulus system is being pumped by aux. cart.  
• CP1 RGA is being pumped down for initial commissioning.
• Flange protection was added to the HAM1 top 16.5" port.

ISI install fixture was installed today. Like LLO, it was kind of tricky, we installed the back (-Y) stand, Randy drove the first I-beam through and we attached to the -X side of the install fixture. The +Y side of this I-beam was then hung from the crane while we grabbed the second I-beam and attached to the +X side of the -Y stand. The outer +Y stand was then brought in to support the I-beams and we took two of the outrigger legs off the middle stand and used the crane to place it as close as we could to the middle of the I-beams. The -X outrigger was re-attached and we spent some time squaring the whole assembly up to the chamber before attaching the I-beams to the middle stand. We tried to seal the chamber up as good as we can, but we don't really have covers for this step. At this point, the fixture is pretty close to where it needs to be, but we need to set the height and pull the +Y stand out of the way. Should be ready to bring the ISI into the LVea and get started with the ISI install first thing tomorrow.

Using a linear combination of LHO:83724, the google slides in G2402303, and talking to Brian/Edgard who arrived for their week long visit today -- we installed the OSEM estimator infrastructure today on PR3 *and* SR3. 

We've only filled in enough infrastructure to ensure that it's function is entirely OFF.
Hopefully we'll get further this week.

The new channels have been initialized in the safe.snap for PR3 and SR3. 
    /opt/rtcds/userapps/release/sus/h1/burtfiles/
        h1suspr3_down.snap
        h1sussr3_safe.snap

We made edits to Brian / Edgard's work on common library parts,
    /opt/rtcds/userapps/release/sus/common/models
        HLTS_MASTER_W_EST.mdl
        SIXOSEM_T_STAGE_MASTER_W_EST.mdl
medm screens
    /opt/rtcds/userapps/release/sus/common/medm/hxts
        SUS_CUST_HLTS_OVERVIEW_W_EST.adl
    /opt/rtcds/userapps/release/sus/common/medm/estim/
        ESTIMATOR_OVERVIEW.adl
        CONTROL_6.adl
(see attached notes for details).

And then I made edits to
    /opt/rtcds/userapps/release/isi/h1/models/
        h1isiham2.mdl
        h1isiham5.mdl
to add PCIE Dolphin IPC senders to send out the calibrated ISI HAM ST1 GS13s that are pre-projected into the PR3 and SR3 suspension point euler basis, and then modified
    /opt/rtcds/userapps/release/sus/h1/models/
        h1suspr3.mdl
        h1sussr3.mdl
top level models to receive those IPC, and pipe them in to top of the new main libary part, the HLTS_MASTER_W_EST.mdl

Finally, after Dave installed the model changes and restarted the ISIs and HLTSs, we edited the sitemap
    /opt/rtcds/userapps/release/cds/h1/medm/
        SITEMAP.adl
 to use the HLTS_OVERVIEW_W_EST.adl.

Everything file I mention above has been committed to its respective location in the svn.
Screenshots of stuff will come in the comments.

Edgard, Oli

In 83662 it was discussed that the osem compensating filter z:p = 10:0.4 wasn't as accurate as it should be. Jeff worked out that the zero and pole from the satamp are 0.3835 Hz and 10.6103 Hz, respectively, so our compensating filter should be the opposite of that, with a zero at 10.6 Hz and a pole at 0.38 Hz.

Today we updated those filters for PR3 and SR3. They appear in all three stages in the initial OSEMINF filter bank (FM1) (H1:SUS-PR3_M{1,2,3}_OSEMINF_{sensor})  as well as in all three stages of the watchdog bandpass filter bank (FM6) (H1:SUS-PR3_M{1,2,3}_WD_OSEMAC_BANDLIM_{sensor}). So where before those filters there were 10:0.4, they now read 10.6:0.38 and have these updated zero and pole values. We've loaded in the coefficient changes.

I've attached the script that we used to update these filters below. It's an edit of Jeff's script in 80189

WP12459 Prototype Estimator

We installed new models for h1isiham2, h1isiham5, h1suspr3 and h1sussr3. DAQ restart was required.

WP12458 New ISI HAM1 Guardian nodes

TJ, Dave B

TJ installed four new guardian nodes, these were added to EDC and a DAQ restart was required.

DAQ Restart

Jonathan H, Dave B.

DAQ was restarted for model changes and EDC additions. Because we are in a vent we elected to do an old-fashioned restart whereby the Trend Writers are not turned off prior to the restart of the EDC in order to maximize the vacuum trend data stream. This does mean that systems following guardian in the edcumaster.txt file will see outliers when using NDS1.

Restart sequence was: 0-leg + EDC, then 1-leg when fw0 had restarted.

In preparation for the new HAM1 ISI and the new PM1 suspension, I've created and started 3 SEI Guardian nodes - ISI_HAM1, SEI_HAM1, ISI_HAM1_BLND. I've also created and started SUS_PM1. These have been added to the Guardian overview screen, and a DAQ restart is immanent. Total node count is now 173.

While prepping the code for the other SEI nodes I noticed that ISI_HAM3 was the only ISI node that was still on common code. The H1 specific versions of the other nodes will redefine a few of the dofs that get paths turned on and off. I spoke with Jim and we decided to bring HAM3 in line with the rest and made a copy of H1 HAM2. Needed to restart this node to pick up the changes since it's a SEI node.

I double checked the positions of PR3 and SR3 before the DAQ restart that's planned for today, SR3 seems to have done a bit of drifting from the LVEA zone4 temperature increasing by ~ 2 degrees. The T cursers denote the power outage. PR3s YAW oplev looks a little different post power outage but its' top mass osems don't really seem to have moved.

Elenna, Matt, Camilla. Continuing ISC component inspection and prep for re-installation from 83858. 

Elenna, Matt and I continued to first contact the optics in pans 1 and 2:  M7, M11, M12 (new 90/10 BS), M13, M15 (New 50/50 BS), M16, M17, M18. After again inspecting some of those we cleaned yesterday, we decided to re-clean some. Some needed multiple first contacting, they aren't all perfect (there is a 1" long incredibly hard to see line on M15 and a mark in the center of M18 photo that I will ask a second option on), but otherwise we are calling these two pans of optics ready for re-installation. 

For M15, I installed the picomotors that I removed from the right handed mount into a left handed siskiyou mount. I installed the manually adjustable actuators removed from the left handed mount into the right handed mount, this will be stored. Notes on how to do this are attached.

Still to be done: decide if M15 and M18 are okay or need swapping, clean optics in pan 3; inspect periscope mirrors; swap out any glass beamdumps we can.
