SRM M0 stage sensor is not healthy

sad

There is a huge peak at 60 Hz in the damping singals on M0 of the SRM suspension. Also the noise floor seems too high compared with PRM. This must be fixed.

Not that it should be prevent looking for and solving the problem, but this is most likely related to Integration Issue 935, see original discovery aLOG LHO aLOG 13556.

Richard will be looking at it this morning, potential cutting ex-vacuo cabling to try to fix this known in-vac problem.

Lots of WDs trips tonight

ETMX has tripped 4 times, and so has the BS.  We have been actuating on ETMX, but don't think that is the proble.  We definitely weren't actuating on the BS, there isn't anyone around in the LVEA.  Most of the time the WD plotting script has failed, I did get a plot for the BS though.

ETMX tripped again, there was no isc feedback this time.  It also tripped several more times while the guardian was trying to bring it back.  We seem to be having an earthquake, but ETMX is the only chamber that isn't riding it out.  Something must be wrong with this ISI.

The problem seems to have been that the configuration of the blends was wrong for both the beam splitter and ETMX.  Jim confirmed that they are supposed to be the same configuration as the rest of the BSC ISIs, so I tried to match all the settings.  It seems like the blend switching doesn't work with the new configuration,so while the ISis were tripped I went into the current blend filter banks individually and switched them all by hand.  At least they are not tripping now. 

How do these blends get switched into the wrong configurations in the first place?  Does someone have a script that sets them corectly?  Do we need to update safe.snaps?

slow feedback from ALS to ETMs

The slow feedback from the green reflection PDH is working again, with the frequency servo on the end station VCOs.  Hopefully this will make locking DIFF easier, since these should help to keep the DIFF PLL within its linear range, which it seems to be doing a reasonable job of right now.

Changes I've made are:

We need to revist the length to PIT for ETMX at verry low frequencies.  This slow feedback is clearly misaligning the cavity.

Also late this afternoon early evening, ETMX ISI has tripped 3 times.  The plotting script failed,

H1 BRS Damper installed but not functioning yet

J. Kissel, K. Venkateswara

We installed and tested the damping turn-table for the BRS. While the basic scheme seemed to be working, we turned it off as we experienced some grounding issues which need to be sorted out.

The turn-table has two 1-kg masses located diametrically opposite. It's angular position between 0 and 90 degrees is controlled by a stepper motor/controller which is in turn controlled by an analog signal between 0-5V.

The control signal is currently being written out by the BRS DAQ program to the USB DAC card. The stepper controller is kept floating so that the control-signal ground defines the ground for it. This was apparently causing the controller to restart irregularly. So I tried grounding one end of the control-signal to the platform (which is grounded through the ion pump). This may have been slightly better but unfortunately there seemed to be a big voltage drop (~2 V) across the DAC card's ground and the platform ground which was corrupting the control signal. Better grounding of the platform and controller may help.

WBSC ISI Overview medms updated

ITMY on the SITEMAP was pulling up ISI_CUST_CHAMBER_OVERVIEW_Z_to_RZ_Decoupling.adl rather than ISI_CUST_CHAMBER_OVERVIEW.adl (this is the misfortune alluded to previously.)

I corrected this on the SITEMAP--you'll need to get a new one.

Additionally, ArnaudP, our old friend, landed a nice chunk of guardian realestate on the overview, very nice, thank you AP!

Medms corrected re aLOG 12441

Through a series of unfortunate incidents, I ended up copying an older BSC-ISI Overview onto the current and lost changes made to naming of IOP_DACKILL channels.

However, following the guidence in the subject alog resulted in incorrect channel names.  The corrections to this guidence are:

 

$(IFO):IOP-SEI_$(IOP)_SEI$(CHAMBER)_DACKILL_STATE, with $(CHAMBER) taking the following values: 'BS', 'ITMX', 'ITMY', 'ETMX', 'ETMY'

This is not correct, it should be:

$(IFO):IOP-SEI_$(CHAMBER)_DACKILL_STATE, with $(CHAMBER) taking the following values: 'BS', 'ITMX', 'ITMY', 'ETMX', 'ETMY'

This line too in the medms needed to be corrected from $(IFO):IOP-$(IOP_NAME)_DACKILL_STATE  to $(IFO):IOP-SEI_$(CHAMBER)_DACKILL_STATE

I have added this correctioin to 12441.

Add ADC and 18bit DAC to h1iscex, h1iscey
Dave, Cyrus, Jim

An additional ADC card and an 18 bit DAC card was added to the I/O chassis for h1iscex and h1iscey.

At EX:

The 18 bit DAC was added to PCIe slot 11 (bus 2-4), making it the first DAC card on the bus.  The 18 bit adapter card was put into slot 2 of the backplane, while the 16 bit DAC adapter card was moved to slot 6 of the backplane. (The 18 bit DAC needs to be the first DAC card in the chassis, forcing the move of the 16 bit DAC adapter card).  The H1:ISC_DAC0 cable followed the 16 bit DAC adapter to slot 6.

There are now 4 ADC cards installed in the I/O chassis, in PCIe slots 1 (bus 0-1), 2 (bus 1-5), 3 (bus 1-4), and 7 (bus 1-6). An additional ADC adapter card was installed in slot 5 of the backplane, and the PEM AA chassis was connected to this card (it was connected to slot 1).  This caused the ADC card for the PEM model to be moved to the last ADC card.  The H1:ISC_ADC0 and H1:ISC_ADC1 cables were not moved, and the ADC card assignment for the h1iscex model didn't change.

The h1calex model would use ADC card 0 and DAC card 0.

At EY:

ADC cards were installed in slot 4, 5, and 6. These were removed, and ADC cards were installed in PCIe slots 1, 2, 3, and 7 to match EX. An additional ADC adapter card was installed in slot 5 of the backplane.

An 18 bit DAC card was installed in PCIe slot 11 (bus 2-4), while the existing 16 bit DAC remained in PCIe slot 10 (bus 2-5).  The 16 bit DAC adapter card was moved from backplane slot 2 to backplane slot 6, with the H1:ISC_DAC0 cable following the adapter card.  An 18 bit DAC adapter card was installed in backplane slot 2, so the 18 bit DAC card is the first DAC on the PCIe bus, and the 16 bit DAC is the second DAC on the PCIe bus.

The h1caley model would use ADC card 0 and DAC card 0.

For both EX and EY:
backplane assignments:
slot 1 ADC - h1cale(x,y) ADC card 0 
slot 2 DAC - h1cale(x,y) DAC card 0 (18 bit) (share with pem model)
slot 3 ADC - h1isce(x,y) ADC card 1
slot 4 ADC - h1isce(x,y) ADC card 2
slot 5 ADC - h1peme(x,y) ADC card 3
slot 6 DAC - h1isce(x,y) DAC card 0 (16 bit)

An error was made on the installation at EX, so data for the h1pemex and h1iscex models is invalid from 09:35 to 15:40 PDT.  During troubleshooting, a power cycle of the h1iscex I/O chassis caused errors on the h1susex and h1seiex models, requiring a restart of those computers.

The IRIG-B timing drifted on startup of EY, so data for h1pemey, h1iscey, and h1odcy in invalid from 11:15 to 13:42 PDT.

Install of new CAL models at both end stations on the ISC front end computers

Cyrus, Jim,  Rick, Shivaraj, Dave

WP4888

Two new H1 front end models were created, h1calex and h1caley. They run on the end station ISC front ends, using the 4th user-model core. We assigned them the next two spare DCU-IDs  (h1calex=124, h1caley=125).

The cal models currently only have the PCAL subsystems. I took the latest version of the PCALX code from h1odcx (where it was temporarily installed for testing) and installed on both end stations. The models' channels have the prefix H1:CAL-PCAL[X,Y]_. The CAL models are located under SVN in the ISC path (isc/h1/models/h1cale[xy])

The CAL models use the first ADC because they require the DUOTONE timing signals. The PEM models were modified to use the 4th ADC. The ISC models continue to use the 2nd and 3rd ADC and did not need modification.

The CAL models use the newly installed 18bit DAC card. This card is also used by the PEM model to drive unused channels (I modifed PEM accordingly).

The DAQ master and H1EDCU_DAQ.ini files were modified to include the new CAL models.

The IOP models h1iopisce[xy] were modifed to add the 4th ADC and 18bit DAC.

All models on the ISC front ends and the DAQ were restarted several times during this install.

Here is a summary list of model changes

h1iopiscex add ADC and 18bit DAC
h1iopiscey add ADC and 18bit DAC
h1pemex switch ADC from 1st to 4th and add 18bit DAC, filter modules to drive unused DAC channels
h1pemey switch ADC from 1st to 4th and add 18bit DAC, filter modules to drive unused DAC channels
h1odcx remove PCALX part from this model
h1calex New CAL EX model. Uses 1st ADC and 18bit DAC (first channel)
h1caley New CAL EY model. Uses 1st ADC and 18bit DAC (first channel)

Optical Levers Motion with Z in High Blend (750mHz)

The first figure attached shows the optical levers motion, Monday at 1 am, with Stage 1 Z under 90 mHz blend.

The second figure attached shows the optical levers motion, Tuesday at 1:15 am (there were some offsets applied around 1:00am), with Stage 1 Z under 750 mHz blend hoping to reduce the Yaw motion at the microseism.

The input motion was very similar for the two measurements.

 

- Results:  All units except (ETMX) show more motion in the Z 750 mHz blend configuration, as summarized in the table below;  I recommend to revert the Z blend back to 90 mHz configuration to see if the results are repeatable. This can be done any time as both configurations provide similar performance anyhow (-> when it is the least disruptive for IFO locking activities),

- Other comment: it would be good to find out why ITMY and ETMY rms are dominated by features below the micro-seism (poor tilt decoupling? noisy sensor?).  This is true in both blend configurations shown in these plots.

 

RMS value of the optical levers down to 10 mHz:

                   Pitch (90mHz Z blend)           Pitch (750mHz Z blend)                   Yaw (90mHz Z blend)          Yaw (750mHz Z blend)

H1 PSL Table-south (incorrectly named) sensor moved away from heat sources
Last week, RobertS and I determined that the North and South PSL table temperature sensors are mislabeled.  North is really South, and vice-versa.  

The South sensor (EPICS channel calls it North) was mounted close to the two major heat sources in the Laser Room that are not water cooled: the TTFSS servo electronics and the ISS AOM driver (see "before" photo below).

Today, I moved it approximately 2 ft. to the West so that is not located on the South-West corner of the table, and away from the heat sources (see second photo attached below).

H1 PSL FSS path maintenance work
PeterK and RickS

- FSS AOM replaced.  Heat sink, aluminum baseplate, kapton insulators, nylon screws added. (see photo below)

- Measured RF power at input to AOM: 22.5 Vp-p -> 7.96 Vrms -> 1.27 W.  About right.

- Aligned AOM.  Power just upstream of AOM: 68 mW; Power just downstream: 58 mW.  85% efficiency.  Very good.

- Second pass, measured just upstream of EOM: 47 mW; 81% efficiency.  Good.  Double-pass efficiency 69%.  Good.

- Power downstream of EOM, downstream of RC modematching lens L12: 47 mW.  Good.

- M27, first turning mirror downstream of EOM was not locked, now is.

- Aligned into reference cavity using two periscope mirrors.  Max Tx PD DC out: 2.37 V.  Locked both periscope mirror mounts.  TxPD DCout after locking mounts: 2.35 V.

- Centered beam on RFPD.  Locked all three actuators on first steering mirror upstream of RFPD.

- FSS RFPD unlocked: 360 mW; locked: 37 mV -> 90% visibility.  Not too bad.

- TTFSS gains (FAST/Common): 15/30 dB; measured UGF 340 kHz; phase margin > 50 deg.  Notch at 770 kHz.  Peaks at 1.77, 1.93, and 2.48 MHz up to within 2-3 dB of unity gain (see photo below).  Probably should be addressed by rolling the loop off more aggressively above 1 MHz, or so.

- Frontend watchdog disabled at start of work, enabled at close of work.

Overall, loop seems to be functioning well.

Plot of the reference cavity transmission and pre-modecleaner output after the work on the AOM.

There are two discontinuities in the reference cavity transmission.  The first probably coincides
with the FSS oscillations noted by Kiwamu earlier today.  The second change might be due to the
common gain being reduced to 18.8 from 30.0.

difficult to transition to 3f for SRCL

I have had a difficulty transitioning the SRCL signal from the 1f to 3f signal. Not solved yet.

After playing with ALS DIFF, I went through the initial alignment process and then moved onto the DRMI. As tested before (alog 14283), the 1f locking with REFLAIR was fine with a laser power of 10 W incident on IMC. However I kept failing in the transition from the 1f to 3f signals tonight. It was due to the SRCL loop which did not like the 3f signal tonight for unknown reason. The PRCL and MICH loops could be transitioned to RF27_I and RF135_Q respectively without a problem. But SRCL seemed to saturate the M2 stage DAC every time (??) when I tried to engaged RF135_I. I tried adjusting the demod phase, but did not seem to help. Also checked the optical gain by exciting SRCL and confirmed that the input element of -2 which was taken care by the guardian is right. Also tried it with two whitening stages on in REFL135, but this did not help either.

Note that the build up of the sideband power looked high tonight:

Also, I had the modified L2P decoupling filter engaged on the M2 stage of SRM (see alog 14304) all the time tonight.

kiwamu.izumi@LIGO.ORG - 18:46, Tuesday 07 October 2014 (14353)

Here is a lockloss science. Not clear what exactly was going on.

I looked at three different lock loss events from yesterday. All of them were associated with very large saturation in the M2 stage of SRM which seemed to trigger instability in SRCL and destroy all the LSC loops eventually within a 2 sec or so.

The attached plot is the one from Oct-07-2014 09:24:22 UTC. In this example, PRCL and MICH had been already controlled by the 3f signals (i.e. RF27_I and RF135_Q respectively). In the middle of the plot, the SRCL 3f signal was ramped up (though it actually ramps down because of the control sign. The 1f signal was ramping down at the same time which is not shown in the plot.) Apparently the SRM M2 stage saturated quite hard. Following the M2 stage, the SRM M3 stage hit the DAC range as well. The BS and PRM M2 stages did not saturate until the loops became completely broken. An oscillatory behavior was seen in all three length signals and it was roughly at 13 Hz. Hmmm...

Refining H1SUSBS Alignment Offset Slider Calibration
J. Kissel

Following a similar procedure as was done for the ITMs (see LHO aLOG 14265), I've refined the calibration for the H1 SUS BS optical lever. The new calibrations are
BS P 6.9522 [ct/urad]
BS Y 3.8899 [ct/urad]

They've not yet been installed; will install tomorrow during maintenance.

DETAILS
------------
Currently, the alignment slider calibration gains are 
4.714 [ct/"urad"]
4.268 [ct/"urad"]
based on dead-reckoned knowledge of the actuation chain (see LLO aLOG 5362).

Sheila and Alexa recently found the alignment values for the beam splitter which gets red light onto the ETMY baffle PDs:
            P ["urad"]    Y ["urad"]
ETMY PD1      184.0        -255.0
ETMY PD4      237.1        -287.7
or a displacement of 
BS P    53.12 * 2 = 106.2 ["urad"]
BS Y    23.70 * 2 =  65.4 ["urad"]
where the factor of two comes from the single bounce optical lever effect.

I spoke with Gerardo who informed me that the numbers Keita had posted (LHO aLOG 9087) for the locations of the baffle PDs on the Arm Cavity Baffles are slightly off from reality. He gave me links to D1200296 (ETM) and D1200313 (ITM), which indicate that the PD locations are identical between an ITM and ETM baffle, and are 11.329 [inches] = 0.288 [m] apart in vertical, and 11.313 [inches] = 0.287 [m] apart in horizontal. Again using 3994.5 [m] for the length of the arm (LHO aLOG 11611), and adding 4.847+0.100+0.020+0.200 = 5.167 [m] for the distance between the HR surface of the BS and the back of the CP, through the thin CP, through the ITM QUAD's reaction-to-main chain gap, and through to the HR surface of ITM, respectively (D0901920), that's a lever arm of 3999.7 [m]. Hence, a displacement of
BS P   0.288 [m] / 3999.7 [m] = 72.01 [urad]
BS Y   0.287 [m] / 3999.7 [m] = 71.76 [urad]

The alignment offset slider gains should therefore be corrected by 
BS P  72.01 / 106.2 = 0.67806 [urad/"urad"]
BS Y  71.76 / 65.4  = 1.0972  [urad/"urad"]
or
BS P  1.4748 ["urad"/urad]
BS Y  0.91141 ["urad"/urad]

The new slider gains should therefore be
BS P    4.714 [ct/"urad"] * 1.4748 ["urad"/urad] = 6.9522 [ct/urad]
BS Y    4.268 [ct/"urad"] * 0.9114 ["urad"/urad] = 3.8899 [ct/urad]

We're now storing 4 alignments for the BS, 
                      P ["urad"]       Y  ["urad"]
BS Aligned              210.6             -271.4
   Misaligned           236.5             -287
   To EY ACB PD1        184               -255

OPTICALIGN Calibration gains have been changed, but only the ALIGNED and MISALIGNED values have been stored. Still need store PD1 and PD4 values, commit the snaps to the userapps repo, and capture a new safe.snap. Turns out there are NO calibration filters in the H1SUSBS M1 or M2 LOCK filter banks yet, so they need not get updated. Will do what I can tomorrow.

Completed OPTICALIGN alignment offset slider calibration refinement this morning: saved ALIGNED_TO_PD1 and ALIGNED_TO_PD4 values, confirming that they're hitting the ITMY baffle PDs. Finally, captured a new safe.snap. Now moving on to optical lever calibration refinement using new values.

SEI MEDM screens updated

SEI MEDM screens were all updated (HAM-ISI, BSC-ISI, HEPI) to account for the recent changes in the IOP Dackill channels names.

Displays are fully functional again for both HAM-ISI and HAM-HEPI. (before/after - notes)

BSC-ISI and BSC-HEPI need the IOP DACKILL parts to be updated so channel names match with chamber names, as It is currently the case on HAM chambers. DaveB has agreed to do those changes, and the related model restarts, next week so the BSC chamber IOP DACKILL channels are named as follow:
$(IFO):IOP-SEI_$(IOP)_SEI$(CHAMBER)_DACKILL_STATE, with $(CHAMBER) taking the following values: 'BS', 'ITMX', 'ITMY', 'ETMX', 'ETMY'

Work was performed under DaveB's WP #4672

$(IFO):IOP-SEI_$(IOP)_SEI$(CHAMBER)_DACKILL_STATE, with $(CHAMBER) taking the following values: 'BS', 'ITMX', 'ITMY', 'ETMX', 'ETMY'

This is not correct, it should be:

$(IFO):IOP-SEI_$(CHAMBER)_DACKILL_STATE, with $(CHAMBER) taking the following values: 'BS', 'ITMX', 'ITMY', 'ETMX', 'ETMY'

This line too in the medms needed to be correct from $(IFO):IOP-$(IOP_NAME)_DACKILL_STATE  to $(IFO):IOP-SEI_$(CHAMBER)_DACKILL_STATE
