Ops Owl Summary: 07:00-15:00UTC (00:00-08:00PT)

Hi State: locked in Low Noise and in Observe for 3+ hours, GRB arrived at 14:14UTC

 

Help: Kiwamu

 

Shift Overview:  IFO was down and trying to lock PRMI when I arrived - 3.5 hours to return to Observe.

- DRMI produced a "Split Mode" 

- MICH Dark and SRC alignment corrected DRMI "Split Mode"

- first return to Low Noise had issues with the ISS Second Loop

- IMC_LOCK Guardian had buttons pushed by humans

- only change was ISS Diffracted Power (increased)

 

Timeline:

- 10:12 to 10:40UTC - IFO in Low Noise Lock with ISS Second Loop issues

- 11:39UTC - IFO in Low Noise Lock and Observe - no ISS issues

Owl shift update - earthquake, then alignment, and then ISS Second Loop issues since lock loss in previous shift

Title: Owl Mid-Shift Update, 10:48UTC, 3:49PT

H1 State: relocking and making it to Low Noise but engaging the ISS Second loop is gltiching all of the ISS and the IFO

Help this shift:  Kiwamu on the phone, Kiwamu's alog about engaging the ISS Second Loop manually, Jim's alog about DRMI Split Mode

Details:

07:00UTC - I arrive and IFO is down due to an earthquake.

07:00-08:00 - PRMI locked 3 times, but can't hold due to the earthquake

08:00-09:00 - PRMI locks and I align, then I transition to DRMI and thus the "Split Mode" announcements start, and after multiple "Split Mode" locks I call Kiwamu, he says do a MICH Dark and SRC align

09:20 - MICH Dark and SRC Align alignments are successful, and I take the IFO to Down and Init, and take IFO to full-lock

10:07:41 - Guardian tries to engage the ISS Second loop, I wait, then start the procedure in Kiwamu's alog, and then he called back and we tried unsuccessfully to engage the ISS second loop

10:40:38 - the IFO lost lock due to our work trying to engage the ISS Second Loop - Kiwamu is drining in

11:03 - IFO has not relocked, but I don't know why since I've been writing the alog...

More to come...

It seems that the ISS issue was related to a too-low diffraction power in the first loop.

Please check the ISS diffracted power and adjust it to 8 +/- 1% if having an issue with the engagement of the ISS 2nd loop.

When the ISS was unsuccessful engaging the ISS, diffracted power was at about 5% which should be 8%. Ideally, the diffracted power should not affect the 2nd loop so much, but in reality, for some reason the stability of the 2nd loop seems to be quite sensitive to the diffracted power only when engaging it. After a few failures in engaging the ISS, Cheryl and I tried to engage it a couple of times by hand with no success. Eventually I accidentally unlocked the whole interferometer because we had a wrong gain in ISS_SECONDLOOP_SIGNAL. Oops.

In the next lock trial, we let the IMC_LOCK guardian do it with the right diffracted power of about 8%. This went very smooth without a failure. Probably we should consider making another PID loop to automatically adjust the diffracted power so as to maintain it at around 8% when engaging the 2nd loop.

Update on Y-Mid leak hunting

John, Bubba, Richard, Gerardo

16:44 Opened 10" valve.  Turbo, LD and QDP80 remained on overnight. Background at 1.1 x 10-08 torr*L/sec.
    ***Left system be for background signal to drop.***
We returned to the center longitudinal seam weld (previously referred as butt weld) on the North side of BT.  Divided the section into 3 equal sections, and bagged them.  Using a rate of 1 L/s of He, for 60 seconds dwell, background at 5.2 x 10-09 torr*L/sec, leak hunting started,:
18:00 Section 1 was sprayed with He, and the other two section were purged with instrument air, we waited for 5 minutes to see a response.  Background did not change.
18:06 Section 2 was sprayed with He, and once again the other two sections were purged with instrument air, no change on background.
18:10 John bags the purge/vent valve.
18:12 Section 3 was sprayed with He, while the other two sections were purged with instrument air.
18:15 Purge/vent valve is sprayed with He, and background value starts going up.  Response was to quick??
18:22 section 3 is purged with instrument air.
18:30 observed max value for background 5.2 x 10-08 torr*L/sec.
19:05 Aux cart connected and pumping on closed purge/vent valve, no change noted on BT pressure.
19:12 left for L U N C H, while Turbo pump pumped He out.

===Activity after lunch===

21:28 Background signal at 5.1 x 10-09 torr*L/sec
21:40 sprayed He at a rate of 1 L/s for 60 seconds on the longitudinal weld seam section 3.
21:43 background signal starts changing, slooooow.
21:50 background signal at 2.1 x 10-08 torr*L/sec
21:50 started purging section 3 with instrument air.
21:51 background at 3.0 x 10-08 torr*L/sec
21:52 background at 4.0 x 10-08 torr*L/sec
21:54 background at 5.0 x 10-08 torr*L/sec
21:56 background at 7.5 x 10-08 torr*L/sec
21:58 background at 9.0 x 10-08 torr*L/sec
22:00 background at 1.0 x 10-07 torr*L/sec
22:03 background at 1.2 x 10-07 torr*L/sec
22:10 background at 1.2 x 10-07 torr*L/sec *
22:28 background at 8.0 x 10-08 torr*L/sec
22:38 Turned off and removed aux cart from purge/vent valve, valve was restored as found, except now space is vented.
22:47 background signal at 4.5 x 10-08 torr*L/sec

At this point we divided section 3 into two sides.
    * East side which is away from the stiffener ring, this one was sprayed first with He, while the West side, close to the stiffener ring, was purged with air, we sprayed as before (1 L/s of He for 60 sec).

22:48 started spraying He on the East side.
23:03 background at 3.1 x 10-08 torr*L/sec, background continues to drop.
23:05 background at 2.9 x 10-08 torr*L/sec
23:05 switched hoses on the 2 sides, now we are going to spray He in the West side and purge with instrument air the East side.
23:05 background at 2.9 x 10-08 torr*L/sec
23:06 background at 2.8 x 10-08 torr*L/sec
23:07 start of He spraying at West side
23:10 background at 2.6 x 10-08 torr*L/sec
23:12 background at 2.8 x 10-08 torr*L/sec  ***
23:14 background at 3.2 x 10-08 torr*L/sec
23:17 background at 4.1 x 10-08 torr*L/sec
23:19 background at 4.8 x 10-08 torr*L/sec
23:20 background at 5.2 x 10-08 torr*L/sec
23:21 background at 5.4 x 10-08 torr*L/sec
23:26 background at 5.9 x 10-08 torr*L/sec
23:27 closed 10" gate valve to isolate turbo pump, LD and QDP80 from vacuum system, but they remain on.

Conclusion,
We think that the leak is somewhere in the small West side of the center longitudinal seam weld, we will continue to test to pinpoint the leak source.

Typo in above - The helium flow rate was ~ 1 l/minute not 1 l/sec.

The suspected leak at the purge valve seems to have been a false positive due to the delayed response from the seam weld. After bagging the purge valve and chamber conflat as one we then removed the bag, removed the nw50 blank, and applied helium directly into the valve, into the test port of the valve body, and into the vacuum side conflat -each for 60 seconds. No response to this so we went back to the longitudinal seam weld. 

The photo shows 2 bagged portions of the seam weld - one purged/inflated with air and the other with helium. We sprayed in both directions - ie swapped air and helium  - no leak detector response was seen in one test while a strong signal was seen in the other. The prior day we saw a response from this area and in violation of my own rule I sprayed the triple conflat on the neighboring valve - again with 60 sec bursts of helium - no response.

The next step should be to try and evacuate the bagged portion of weld seam. This may prove to be a quicker and more definitive test than the helium testing, although the geometry is very tricky as the the weld is hidden by the vertical support structure and the stiffener stitch weld also crosses the seam weld.

H1 dropped unexpectadly.  StripTools showed oscillations on LS-POP_A_LF and the SRM & PRM a few minutes before the lockloss.  Then Vinny noticed the increase in the EQ band (0.03-0.1Hz).  Then Terramon finally displayed the 5.6 EQ from Russia.  We dropped out before the R-wave estimate, but fairly certain the EQ is what knocked us out (and also knocked L1 down 3min after us).

X-End Station Annulus Ion Pump Update (BSC5)

John, Gerardo

Today I got a chance to check the AIP that was installed last week (here), unfortunately the pump was railed, and (2x)unfortunately we don't know when it railed, no data available for this ion pump yet (working on it, data is comming soon).


We have an old valve that appears to be faulty, to patch that problem I added another valve in-line until we get a replacement, I used the aux cart to pump down the annulus system for 3 hours during the maintenance period, but that amount of time was not enough to keep the controller from railing.  We left the aux cart pumping on the annulus system, and it will remain pumping until the controller can maintain the system without railing.

16:27 - aux cart is connected and turned on, and remains on.
20:18 - aux cart was set on top of shipping foam, 3 points for seismic isolation.

Location of the aux cart:
It is on the East side of BSC5, see photo.

Low Voltage ESD monitor analog measurement (Elli, Keita)

Related: alog 22199

We measured the output of the Low Voltage ESD monitor (D1500129) at the AA side at the remote rack using SR785 right after the IFO was locked up again after the maintenance.

No surpise was found, see attached. 'UR', 'UL' etc. are the analog measurements of the corresponding ESD monitor. Noise floor was measured with the inputs of SR785 short circuited.

Don't worry about LR trace, it looks as if it's noisier than the others but it's not, it's just the spectral leakage artefact (somehow I did not save the small BW measurement for LR).

'digital LL signal projected' is H1:SUS-ETMY_L3_MASTER_OUT_LL, but with a correction of 20/2^17 Volt/count for DAC conversion, zpk([50;50;3250], [2.2;2.2;152]) for SUS awhite type filters, and 2 *4.99/(1.2+15+4.99)*zpk([],[40]) for the monitor circuit.

The measurements agree well with the projection up to 1kHz. Higher than that, the SR785 noise dominates, but this should be good enough for our purpose.

What was done:

We disconnected the LV ESD monitor cable (SUS ESD 06) from the front panel of the AA, and connected DB9 breakout board to the cable but not to the AA.

For each quadrant (pin1-6 for UR, 2-7 for LR, 3-8 for UL and 4-9 for LL), we used two clip-BNC cables to connect the positive pin (1, 2, 3 or 4) to A connector of SR785 and negative to B, and the BNC shell was connected to the shell of the DB9 connector on the AA chassis.

SR785 was in A-B mode, AC coupled. The plot doesn't account for the AC coupling, but its roll off is at 0.16Hz and does not affect the plot. Sensitivity was fixed at -8dBVpk.

Low frequency measurements (0-400Hz, 800 lines) were performed for all quadrants but it was not saved for LR. As a result, in the plot it looks as if LR is noisier than the other channels, but in reality it's showing the spectral leakage artefact due to larger bandwidth measurement for f<400Hz.

Higher frequency measurements (0-1.2k and 0-12.8k, 800 lines) were performed and saved for all quadrants.

Only for LL we measured up to 102kHz to make sure that there's no high frequency bump or anything, but all measurements are dominated by SR785 noise for f>1kHz anyway.

Attached is the matlab file containing the voltage data for all quadrants and the SR785 noise.

Um, count-to-voltage DC gain conversion of the DAC is 20Vpp differential per 2^18 counts. So the grandparent entry is incorrect by a factor of 2 there. But I'm measuring the voltage in the differential output stage of LV driver which has the DC gain of 2 (i.e. 10V pp single ended is converted to 10V pp differential), which I didn't account for in the script.

So in the end the conclusion doesn't change.

Improvement in 300 Hz periscope optic mount peaks still holding after 3 hours of lock

The figure shows the features produced by the optic mount at the top of the periscope before maintenance (red) and 3 hours after recovery from maintenance (blue).  The amplitude seems reduced by nearly 10, but lets see how it ages. I used a watercolor paint brush to apply 5 minute epoxy to the base of the U-200 mount at the top of the periscope. I used one brush load. I was only able to paint the epoxy at the left and right sides of the mount because the middle was over a cutout in the base plate. After the epoxy was mostly cured, I adjusted weights on the periscope and optic, minimizing the peaks in IMC_F by placing them in valleys between periscope resonances.

non stationary noise in DARM that appeared Oct 12th

Jordan, Sheila

In the summary pages, we can see that something non stationary appeared in DARM from about 80-250 Hz durring the long lock that spanned Oct 11th to 12th, and has stayed around.   Links to the spectra from the 11th  and the 12th.  

HVETO also came up with a lot of glitches in this frequency span starting on the 12th, (here) which were not around before.  These glitches are vetoed by things that seem like they could all be realted to corner statin ground motion: refl, IMC and AS WFS, all kinds of corner station seismic sensors, PEM accelerometers, MC suspensions.  

Although this noise seems to have appeared durring a time when the microseism was high for us, I think it is not directly related. (high microseism started approximately on the 9th, 2 days before this noise appeared and things are quieting down now but we still have the non stationary noise sometimes up to 200 Hz.)  

The blend switching could also seem like a culprit, but the blends were not switched at the begining of the lock in which this noise appeared, and we have been back on the normal (90mHz blends) today but we still have this noise.  We've seen scattering from the OMC with velocities this high before (17264 and 19195).  

Nutsinee and Robert have found that some of the glitches we are having today are due to RF45, but this doesn't seem to be the case on the 12th.

The first plot attached is a timeseries of DARM vs RF45 mod of the 10/11 - 10/12 lock stretch (~25 hours). The second plot is the same channels during the beginning of 10/13 lock stretch (30 minutes). You can see RF45 started to act up on 10/13. I've also attached the BLRMS plot of DARM using the bandpass filter Robert used to find the OMC scattering. The none stationary noise we see is likely caused by two different sources.

Here is one example of one of these glitches rlated to ground motion in the corner that we had durring high microseim over the weekend (but not the entire time that we had high mircoseism). This is from Oct 12th at 14:26 UTC.  Even though these have gone away, we are moitvated to look into them because as Jordan and Gabriele have both confirmed recently, the noise in the unexplained part of the spectrum (50-100 Hz) is non stationary even with the beam diverter closed. If the elevanted ground motion over the weekend madde this visible in DARM up to 250Hz, it is possible that with more normal ground motion this is lurking near our sensitivity from 50-100 Hz.

If you believe these are scattering shelves.

  • The upper limit of the shelf is at 200-250 Hz, so the maximum velocity (lambda*f_max/(4pi)) is around 35-42 um/sec. 
  • There are about 9 arches in 4 seconds, so the frequency of the motion should be (9/4)/2  ~1.1 Hz (We see 2 arches in each period of the motion.) 
  • So something should be moving with an amplitude of 17-21 um at around 1 Hz, if the scatter path is double passed (IFO to scatterer and back only once).

See josh's alogs about similar problems, especially 19195 and recently 22405

One more thing to notice is that at least in this example the upconversion is most visibe when the derivative of DARM (loop corrected) is large.  This could just be because that is the time when the derivative of the ground motion is large.

Nairwita, Nutsinee

Nairwita pointed out to me that the non-stationary glitches we're looking at was vetoed nicely by HPI HAM2 L4C on October 12th, so I took a closer look. The first plot attached is an hour trend of DARM and HPI HAM2 L4C. But if I zoom into one of the glitches it seems to me that there's a delay in response between HPI and DARM up to ~10 seconds from just eye-balling it (second plot). I've also attached the spectrogram during that hour from the sumary page.

Comparing stationarity Oct 5th to Oct 12th

I ran Dan's code to compare stationarity between two hours on Oct 5th and Oct 12th.  The closure of the beam diverter on the 6th was thought to help stationarity in the 70-100hz region, so I included versions zoomed in on that frequency range.

I tried to pick times that were not affected by huge glitches / range drops. On the 5th the two hours were 1:00-3:00UTC and on the 12th 00:00-02:00UTC.

Sheila, Jordan

Made the same plots to compare the stationarity during times when anthropogenic seismic was quiet / loud. The 1-3 and 3-10 hz seismic bands pick up around 14:00 utc weekdays, and the data seems to become more nonstationary in the 100-200 Hz band during this time.

On the 12th, there is some unknown stuff going on at lower frequencies, and the ~300 hz periscope peaks are still visible. But just looking at the 100-200 hz region shows correlation with ground motion. Also have the same correlation on the 14th (spectrum overall looks very stationary, though).  Mechanism still unknown... scattering?

Added PRMI branch to ISC_LOCK guardian

I've rearranged the PRMI branch in the DRMI guardian, and added states to the ISC_LOCK guardian to request both these states and the ALIGN_IFO states used for PRMI  (finshing unfinished item from WP5533).  This is for use when you think that the DRMI alignment is bad (based on the AS camera and the flashes as seen in dataviewer)  and will not lock.  If DRMI is slow to lock but has been locked recently and looks well aligned on the AS camera, this procedure is probably not your best bet.

We will test this durring maintence recovery today, but the instructions replacing those in 21745 will be:

This has now been tested, and had some bugs but after fixing several typos we made a sucsesfull transition from PRMI to DRMI.  If you are trying to lock DRMI and decide to change to PRMI, you would need to take ISC_LOCK to manual, then request LOCK_PRMI, and go back to AUTO.

SUS OSEMINF and NOISEMON Spectra Templates added to OPS directory

On Tuesday, while most of the IFO was down for various maintenance tasks, I grabbed a bunch of SUS spectra and started a Template directory. 

I set all of the references to be the ~quiet, unlocked data from the down period of the IFO.  These spectra could be run when trying to troubleshoot locking.  On Tuesday, I was only able to collect the following, located in /ligo/home/ops/Templates/SUS_Spectra/

NOTE - Many of the lower stage NOISEMON channels look... weird.  They should be used as a before/.after snapshot for troubleshooting only.  Work to improve what the various strangenesses of these channels is on a few low priority to-do lists.

There are templates ready to collect the balance of the SUS spectra data, namely ETMs, MCs, PR3.  We should do this when the IFO is set to DOWN for whatever reason.  The spectra are quick to run, then update all references (currently bogus data) and resave.

While we were unlocked due to wind during my Sunday Owl shift, I managed to get through taking, updating, and resaving templates for:

ETMX_NOISEMON_spectra.xml

ETMX_OSEMINF_spectra.xml      

ETMY_NOISEMON_spectra.xml

ETMY_OSEMINF_spectra.xml  

PR3_NOISEMON_spectra.xml

PR3_OSEMINF_spectra.xml
