IMC Power Increase during NOMINAL_LOW_NOISE, ISS 2nd loop reference signal adjustments

B. Weaver, J. Oberling

After this morning's PSL trip there was a 0.5W increase in IMC-PWR_IN, observed ~15 minutes after reaching NOMINAL_LOW_NOISE.  We started digging in the Guardian code and rediscoverd that the ISS diffracted power gets adjusted by a software PID loop located in the IMC_LOCK guardian; this adjustment is done via changing the ISS 2nd loop reference signal.  At the start of a lock stretch this PID loop is necessary to keep the ISS diffracted power around the predetermined nominal value of 8%.  However today we witnessed that when the diffracted power trended towards the upper threshold (set in the IMC_LOCK guardian code) of 10%, the IMC_LOCK turned on the PID loop, thus increasing the measured IMC-PWR_IN by ~0.5W.

Looking back 16 days we discovered 2 more cases of the IMC_LOCK guardian turning on the ISS PID loop during a NOMINAL_LOW_NOISE (and observing) lock stretch.  Attached is the 16 day trend and the 2 examples.  The 2nd example was 30 hours into last week's 46 hour lock stretch.  Also note, in the 16 day trend, the continued power discrepancy from lock to lock.

Looking at the 16 day trend, by eye it seems the ISS diffracted power is hugging the upper threshold of 10% more often then not, hovering around 9%.  This might be normal acceptable behavior, however we were surprised to see that a PID loop was increasing power in the middle of an observing lock.  Will follow up with commissioners.

What do the in- and out-of-loop signals for the outer loop look like during these events? (I.e., SUM14 and SUM58.)

jeffrey.kissel@LIGO.ORG - 17:21, Monday 28 September 2015 (22038)
B. Weaver, J. Kissel,

Not sure what Evan wants with the "SUM14" and "SUM58" channels, so I found what channels are stored in the frames for the ISS, and used my vague knowledge of how the ISS SECOND LOOP works, and chose
H1:PSL-ISS_SECONDLOOP_SUM14_REL_OUT_DQ
H1:PSL-ISS_SECONDLOOP_SUM58_REL_OUT_DQ
and reproduced Betsy's plots with trends of those channels in addition to the original channels. 

I'll leave it to Evan to interpret the results, 'cause we don't know how.

Let us know if you need anything different, Evan (or on a different scale, or whatever).

Back to Observing 19:56 UTC

I switched to Observing a bit at 19:49 after Praxxair hadn't moved for a really long time. I went back to comissioning then the truck took off from Mid Y at 19:51. And back to Observing when it went back to Rt. 10.

The PSL AOM diffracted power was dropping but now stable within desired range (8%). Peter went to turn on the laser Watchdog.

Lockloss 18:11 UTC

PSL tripped.

peter.king@LIGO.ORG - 11:48, Monday 28 September 2015 (22024)
Sitting in the control room I heard something about a lock loss.  I looked at the monitor that displays various cavity
transmissions and noticed that the laser had tripped.  I went into the diode room.  The Beckhoff computer indicated
that the laser switched off due to the power watchdog being kicked.

    The power watchdog performed as it should.

    However we should make it routine to reset the power watchdog every maintenance day.  Something we have mentioned
but perhaps were not as diligent about it as we should be.

    All the PSL related servos were up by the time I returned to the control room.

    Attached is a plot of the laser power since the last time (I believe) the watchdog was reset back on
Sept. 1st.

Locked again at NOMINAL_LOW_NOISE. RF45 MODE reduced to 22.2 dB after it was reset to 23.2 by Guardian after the lockloss. Currently not Observing due to Praxxair (a really big truck) on site.

peter.king@LIGO.ORG - 13:08, Monday 28 September 2015 (22029)
When the laser was restarted the main screen indicated that the laser power was 34.7 W.  Instead of turning
on the watchdog there and then I decided to wait and let the power stabilise out before setting the dog loose.
Turned on the watchdog at ~13:05 UTC, the power indicated on the screen was 34.1 W.

WHAM5 ISI Top model Modelified to Temporarily Fix Rogue Ext Trip Issue

re Int Issue 1127, WP 5521.

Have modified the WHAM5 Top Level Model to terminate the output of the ADC and ground the input of the Coil Driver Corner2 Voltage monitors.

This will eliminate the false Rogue Excitation WD Trips of which this platform has been suffering.  BTL identified the cause finding the bad monitor output.

This is temporary until we swap out the driver and look for a cause in the monitor circuit.

On Tuesday 29 Sept, the model will be installed and the FE restarted after taking the platform down to safe or offline.

After restart, the SDF will have to be repointed to the OBSERVE.snap

Attached is an image of the modified model area: the two don't look like the others.

Modified model commited to svn rev 11742.

Dropped RF45 modulation index by 1 dB

The glitch rate hasn't been doing very well in the past hour (since I relocked the ifo) so I dropped the intent bit and reduced the modulation index (17:37 UTC) by 1 dB. The  H1:LSC-MOD_RF45_AM_RFSET value is now 22.2 instead of 23.2. I went back to observing with this configuration and see if it helps with the glitch rate. So far the DMT Omega has been looking much cleaner in the past 10 minutes.

Lockloss 15:50:47 UTC

Lockloss after 60 hours locking at NOMINAL LOW NOISE (beat the old record of 46 hours from three days ago). There's a 5.4M earthquake in Argentina at a depth of 198.5km happened right around the time. Terramon suggested this earthquake shouldn't drop us out of lock but LLO has also dropped lock at the same time. USGS reported no bigger earthquake.

Out of Observation one more time

The RF Noise isn't quite as bad this time, for the past 10min or so it will breifly get noisy, relax for min, then get noisy againa and saturate ETMY.

LLO is down right now so I will take that opportunity to try and fine tune the RF45Set again.

Narrow lines in H1 DARM in O1 week 1
Executive summary: 
  • In regard to narrow lines, early O1 data resembles early ER8 data: a pervasive 16-Hz comb persists throughout the CW search band (below 2000 Hz); there is a notable 1-Hz comb below 100 Hz (0.5-Hz offset); and other sporadic combs persist.
  • On the other hand, there are distinct improvements: noise floor is cleaner nearly everywhere and substantially lower in the 10-70 Hz band; non-linear upconversion around quad violin modes and harmonics is much reduced; some combs and isolated lines have disappeared; and the OMC alignment dither frequencies have moved out of the CW search band (hurray!).
  • Oh the third hand, new artifacts have appeared or strengthened: a sporadic 8-Hz comb suspected before is confirmed; a 1-Hz comb (no offset) has emerged below 70 Hz; a broad bulge appears in the 1240-1270 Hz band.
Details: Using 104.5 hours of FScan-generated, Hann-windowed, 30-minute SFTs, I have gone through the first 2000 Hz of the DARM displacement spectrum (CW search band) to identify lines that could contaminate CW searches. This study is very similar to prior studies of ER7 data and ER8 data, but since this is my first O1 report, I will repeat below some earlier findings. Some sample displacement amplitude spectra are attached directly below, but more extensive sets of spectra are attached in zipped files. One set is for O1 sub-band spectra with labels (see code below), and one set is an overlay of early ER8 spectra (50 hours) and the early O1 spectra. As usual, the spectra look worse than they really are because single-bin lines (0.5 mHz wide) appear disproportionately wide in the graphics A flat-file line list is attached with the same alphabetic coding as in the figures. Findings:
  • A 16-Hz comb pervades the entire 0-2000 Hz band (and well beyond, based on daily FScans)
  • A typically much weaker and sporadic 8-Hz comb (odd harmonics) is also pervasive - previously suspected, now confirmed (all harmonics are labeled in figures, even when not visible)
  • A 1-Hz comb with a 0.5-Hz offset is visible from 15.5 Hz to 78.5 Hz (slightly wider span than before)
  • A new 1-Hz with zero offset is visible from 20.0 Hz to 68.0 Hz
  • A 99.9989-Hz comb is visible to its 8th harmonic (was previously visible to its 13th harmonic)
  • The 60-Hz power mains comb is visible to its 5th harmonic (was previously visible to its 9th harmonic)
  • There is a sporadic comb-on-comb with 0.088425-Hz fine spacing that appears with limited spans in three places near harmonics of 77, 154 and 231 Hz (ambiguity in precise fundamental frequency)
  • There is a 31.4149-Hz comb visible to its 2nd harmonic
  • The OMC alignment dithers have been moved to above 2000 Hz (thanks!)
  • Upconversion around the quad violin modes and their harmonics is much reduced, although the strengths of the higher harmonics themselves remain high. To be more specific, the fundamental and higher harmonics of the upconversion itself (integer harmonics) due to the fundamental violin harmonics are highly suppressed, while the higher harmonics of the violin modes themselves (not integer harmonics) remain high.
  • A number of previously seen combs are no longer apparent: 59.3155 Hz, 59.9392 Hz, 59.9954 Hz and 75.3 Hz
  • A variety of single lines have disappeared, and new ones have appeared (see attached line list)
  • Compared to early ER8 data, the noise floor is slightly lower in most of the band and significantly lower in the 10-70 Hz band, but there is a significant new bulge in the 1240-1270 Hz band

https://ldas-jobs.ligo.caltech.edu/~keithr/spectra/O1/H1_O1_week1_0-2000_Hz.mat

Keith has found:
"There is a sporadic comb-on-comb with 0.088425-Hz fine spacing that appears with limited spans in three places near harmonics of 77, 154 and 231 Hz (ambiguity in precise fundamental frequency)"

Using the coherence tool, we have seen coherence between h(t) and a number of auxiliary channels that shows this comb around 77 Hz. Seems to be around the input optics, in channels:

The structure at 76.4Hz Nelson listed some channels for above shows up in at least 50 other channels. 

Greatest coherence is consistently at 76.766 Hz, second greatest is (mostly) consistently at 76.854Hz. 

Spacing between the two combs is about 0.0013Hz.

The epicenter seems to be the INPUTOPTICS/the SUS-BS and SUS-ITM* channels, like Nelson said (see below for fuller list).

The plots above are pretty typical, but I have plots for all channels listed and can post any more that are useful. Most or all channels showing the comb with max coherence greater than 0.1 are listed below. Max coherences over 0.2 are marked below as strong, and max coherences under 0.15 as weak. Those marked strongest are around 0.22. I haven't included anything of max coherence <0.1 but I'm sure there are many.

The 99.9989Hz comb Keith found (designated H) appears in 109 channels (list is attached). Coherence is uniformly greatest at the ~500Hz harmonic, with many channels approaching .7 and greater, drops off sharply at the ~600Hz and ~700Hz, and is invisible after 700. (See spreadsheet titled "comb_H_sigcohs_wk1.xslx" for a list of cohering channels by line, with coherence value.) 

At all harmonics except the ~300Hz, the structure manifests in the signal and the coherences as two lines .001Hz apart, but if I recall correctly .001Hz is the resolution of the frequency series, so it's safer to say that this is a bulge with .001Hz < width < .002Hz. At ~300Hz, almost all the cohering channels with data in that range show a bulge of width about 0.5Hz (see attached "disjoint_plots" for a comparison of typical channels by harmonic). This bulge, and the fact that it appears in all the same channels associated with the rest of the comb, makes me think that the fundamental may be the bulge at ~300Hz and not the line at 99.9989Hz. An interesting feature of the bulge is that in many cases, it has a prominent upward or downward spike at 299.96Hz, which is just the place the line would be if it were there (see "bulge_w_spike.jpg").

More to come re: changes in week 4 data, patterns in cohering channels, and the spike.

Hardware injection testing for lower frequency waveforms
We tested a set of waveforms to see if they would saturation the ETMY ESD.

Test the 15Hz waveform

Previously we have tested a waveform that began at 30Hz, see aLog 21838. It was requested we try it from 15Hz instead of 30Hz.

Here are the commands I ran for testing the 15Hz waveform:

The start times of the injections from the log file (log3.txt):

I did not notice any ESD saturations.

John's waveforms

John V. has also provided 10 waveforms that I tested, see aLog 21964.

Cautiously testing the first waveform

Here are the command I entered as I slowly scaled up the first waveform's amplitude:

The injection that began at 1127280433 was near an ETMY alert from the robot voice. The ETMY alert happened a bit after the injection happened. SO I waited, I repeated the same injection, and there was no alert.

I did one of these injections with a padding of 10 minutes so if the search groups are going to followup one of these injections in more detail this would be a good choice:

The start time of this injection is:
SIStrOpen: Waveform starts at GPS=1127281956, epoch=0, sample=0

Testing the other nine waveforms

Then I tested the remaining 9 waveforms by beginning with a scale factor of 0.3333 and incrementing to 1.0. I did these with little spacing between the injections so I do not think this set is worth the analysis groups following up. However, I think the injections with scale factor 1.0 should be looked at for ESD saturation (I believe Andy has a script for that):

As I did these injections I had the SUS-ETMY_L3_ESDOUTF_LL_OUT channel open in dataviewer. I did not see any injection go above the 90000 counts. The highest was posterior0*.out which was near 80000 counts.

I am going to follow up the injections I passed to Chris. Assuming the "start time" is the time at the 1st sample of the injection file (and not the 1st non-zero sample) the end times of the increasing amplitude posterior0 injections should be around

[1127278112.46, 1127278216.46, 1127278755.46, 1127279100.46, 1127279527.46, 1127279651.46, 1127280130.46, 1127280440.46, 1127281239.46, 1127281963.46]
 
and for the scan through posterior injections 1-9 with increasing amplitude they are
[1127282020.46, 1127282073.46, 1127282127.46, 1127282180.46, 1127282233.46, 1127282285.46, 1127282333.46, 1127282384.46, 1127282429.46, 1127282483.46, 1127282524.46, 1127282584.46, 1127282638.46, 1127282688.46, 1127282734.46, 1127282777.46, 1127282826.46, 1127282971.46, 1127283014.46, 1127283055.46, 1127283096.46, 1127283167.46, 1127283211.46, 1127283252.46, 1127283299.46, 1127283345.46, 1127283447.46]
 
I'm going to just run all of these since they should be quite cheap to do. I'll post an update when the runs complete.
