'Tidal ' drive runout and lock-loss---PSL temp and RefCav Power

Referring to PeterK's log, 51658, while the Supermoon will change the Earth tides, these effects will be a few percent not a factor of four.  Nor will these normal tidal forces produce a discontinuity as seen in JeffBs' plots in logs 51648 and 51650, and herein.  Even if the IFO were to remain locked for an entire year allowing the tertiary affects (seasonal) to 'drift' the DC level of the tides, the total range on the system would be less than +- 400u and certainly not 700u in 30 hours.  This world would be in a world of hurt if that were the case.  This extreme excursion of demand is causally related to the PSL incursion on Thursday.  And given that this caused a lock-loss, warrants an FRS.  Possibly the operation of or procedure of running the AC in the PSL area needs adjusting.  Alternatively, the locking of the RefCav with a 10-20% step in power may be the culprit.

I suspect that the temperature excursion of the PSL room while not getting to the PSL RefCav temperature sensor, the laser table is warmed up and this slowly flows into the reference cavity via its legs.  Alternatively, I see that the PSL-FSS_TPD_DC output jumps 10+% up after the Thursday activity.  I see the RFPD of the FSS also steps up so something upstream increased laser power.  Could this increase of power just be warming and increasing the RefCav length--seems plausible.  The attached plot shows the step and very slow trend back down of the FSS Slow loop (Ch3) which is putting a wavelength change on the 1u light.

So, I see the room temperature change and the increase RefCav power warming and increasing the length of the RefCav evidenced in the slow loop control. Could this be mitigated to reduce risk of lockloss? Maybe. Change AC operation, monitor & shunt 'excess' power going to RefCav to keep it heat load the same.

Attached plot shows 8 days of LASER room temp, 'tidal' drive to EX HEPI (EY similar,) FSS_NPRO_TEMP, and the FSS_TPD_DC.

ITMX/Y green photos not helpful for camera reference 

I took some photos of the ITMY and X in the hope that the test mass earthquake stops would be visible, and usable as a reference to restore the cameras to their original positions should they get bumped again.  These photos were taken when we were out of lock, and with the illuminators on, and using the green camera.  The earthquake stops are not really visible, and the prospect of using these as references to return the cameras to their optimal positions is not promising.

TITLE: 09/03 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: TJ
SHIFT SUMMARY:  Rough shift for locking, much like the past several days.
LOG:

Ran Initial Alignment.  After IA completed, would either lose lock at FIND_IR or it wouldn't be able to find COMM IR.  I tried adjusting the COMM offset like usual, but could never find resonance.  After a few attempts at this, I re-did IA thinking that perhaps it didn't finish correctly although I didn't notice anything out of the ordinary during the sequence.  After second IA, IR locked and moved on. 

After several attempts at locking and struggling to get past DRMI, H1 went all the way to NLN in a single attempt. 

Looking at the last 3 relocking periods that are shown on the range plot on the wall, they are almost identically ~4 hours long.  Interesting, but not necessarily in a good way.

IS BRSX OK?

Ed called about difficulty locking, since I don't see anything obvious I looked at BRS channels I foudn trended here: 51338.  It looks like the low frequency BLRMS of BRS X has been growing exponentially.

I don't see anything problematic really in the time series. But I did notice from the Detchar summary pages that there was some weird behavior with the inside temperature for a few hours from 16 UTC yesterday (02/09/2019). It takes hours until the BRS itself responds to temperature changes so I'm just guessing but you might be seeing the effects of that. You might consider turning the sensor correction to NON BRS state and lock since the wind is low now anyways. Here is the plot of the temperature

?

I don't think there is anything wrong with BRSX. First attached trend are 7 weeks of the both BRS driftmons, which are kind of a measure of the DC position. BRSX is close to the level where I would want to recenter, but I hope to push that off until we try to install Eyal and Arnaud's heating pad. I don't think the "strangeness" Eyal notes is anything to be worried about. It's a tenth of a degree, from 8am local to about 4pm, probably the aircon.

Second plot are 4 days of trends for ISC_LOCK (top left), the sensor correction control signal generated from the tilt subtracted STS (bottom left) and the drift (top right) and velocity of  BRSX (bottom right). I don't see any signals in the right 2 plots that would cause the spikes in the sensor correction (so I'm assuming they are earthquakes, but I'll keep looking), or would be any cause for concern.

I don't know why the lowest frequency BLRMS of the BRS seem to accumulate these large numbers but I don't think it's a problem. Or if it is, both BRS are busted. Third image is the BLRMS for both BRS for the last 2 weeks. Maybe this is some sort of computational weirdness? Some integrator in the BLRMS filter? Maybe we should periodically clear the histories of some of the filters.

I've looked at few non-brs blrms channels and all of the dc-30mhz blrms channels show this same behavior. The 30mhz low pass is just integrating non-sense. There is no easy way to clear the history of the filter that does the calculation, without restarting the model. Dave and I are talking about adding an epic variable to zero out the filter. We will try prototyping on the test stand.

DetChar Safety Hardware Injections starting at 23:00:00 UTC 3 Sep 2019 
Pursuant to LIGO-T1900555 [1] and discussions on the DetChar and HW injections mailing list [2,3], I've scheduled DetChar safety injections to begin at 23:00:00 UTC (18:00:00 CDT, 16:00:00 PDT) 3 Sep 2019. These should last for 390 seconds and contain 75 injections spaced 5 sec apart.

The scheduled injections have been added to GraceDb [4]. We will update the events in GraceDb to record whether these injections were successful post-hoc.

**Please note**, we have schedule coincident (but not necessarily coherent) injections at LLO for the same time. We include the LLO aLOG describing those injections in a comment below.

More details on how these injections were generated and added to the HW injection SVN repo are available via a README [5].
