Here is what I did tonight:

- I found an input matrix for sensing PRC2 (PR2) in full lock, by requiring that it doesn't see CHARD:
    0.5*(REFL 9I A + REFL 9I B) + 0.83*(REFL 45I A + REFL 45I B) --> PRC2_P (PR2)
  This was the crucial missing piece that was hurting us for CHARD engagement. Now PR2 is servoed faster than CHARD using this CHARD-independent error signal.
  The REFL I input matrix is therefore
        #REFL 9I A - REFL 9I B ->  INP1 (IM4)
        ezca['ASC-INMATRIX_P_1_9'] = 1
        ezca['ASC-INMATRIX_P_1_13'] = -1
        ezca['ASC-INMATRIX_Y_1_9'] = 1
        ezca['ASC-INMATRIX_Y_1_13'] = -1
        # 0.5*(REFL 9I A + REFL 9I B) + 0.83*(REFL 45I A + REFL 45I B) --> PRC2_P (PR2)
        ezca['ASC-INMATRIX_P_4_9'] = 0.5
        ezca['ASC-INMATRIX_P_4_13'] = 0.5
        ezca['ASC-INMATRIX_P_4_11'] = 0.83
        ezca['ASC-INMATRIX_P_4_15'] = 0.83
        ezca['ASC-INMATRIX_Y_4_9'] = 0.5
        ezca['ASC-INMATRIX_Y_4_13'] = 0.5
        ezca['ASC-INMATRIX_Y_4_11'] = 0.83
        ezca['ASC-INMATRIX_Y_4_15'] = 0.83
        #REFL 9I A +REFL 9I B -> CHARD
        ezca['ASC-INMATRIX_P_10_9'] = 1
        ezca['ASC-INMATRIX_P_10_13'] = 1
        ezca['ASC-INMATRIX_Y_10_9'] = 1
        ezca['ASC-INMATRIX_Y_10_13'] = 1
- Also set the PRC2 input matrix back to (1,0,0,0) in the DRMI ASC setup to make sure the DRMI angular control guardian still works.
- Noticed that the PR pointing loop output matrix denationalization for yesterday was not in the guardian. (These were found in DRMI configuration, by requiring that none of the WFS loops need to do any work for pointing changes). Added the following to the DRMI guardian ASC setup:
        # PRC1 -> PRM
        ezca['ASC-OUTMATRIX_P_1_3'] = 1
        ezca['ASC-OUTMATRIX_P_2_3'] = -0.160 # to remove coupling to PR2
        ezca['ASC-OUTMATRIX_P_9_3'] = -0.456 # to remove coupling to SRM
        ezca['ASC-OUTMATRIX_P_10_3'] = 0.060 # to remove coupling to SR2
        ezca['ASC-OUTMATRIX_P_15_3'] = 0.044 # to remove coupling to IM4
        ezca['ASC-OUTMATRIX_Y_1_3'] = 1
        ezca['ASC-OUTMATRIX_Y_2_3'] =  0.170 # to remove coupling to PR2
        ezca['ASC-OUTMATRIX_Y_9_3'] =  0.284 # to remove coupling to SRM
        ezca['ASC-OUTMATRIX_Y_10_3'] = 0.040 # to remove coupling to SR2
        ezca['ASC-OUTMATRIX_Y_15_3'] = 0.008 # to remove coupling to IM4

 - With this setting I was able to engage the following WFS:
  - MICH was never turned off
  - DHARD was already on
  - INP1
  - PRC2
  - CHARD
  - PRC1
  - SRC2
  - SRC1
- The order above is what I expect to work best for engaging. 
- However, the PRC2 loop works so well, and has high enough gain, that directly engaging all 12 loops (6 pit and 6 yaw) at the same time seems to work.
- I tested that twice - with a rather bad initial alignment.

- I left the IFO locked in the engage ASC state - I want to see how much it drifts over night.

When I came in today the ALS kept killing the MC, presumably to a bad alignment. So I tried to take the IFO through an initial alignment using the ISC_DOF guardian.
 - I had trouble with YARM_ALIGN_IR - The REFL_WFS_CENTERING didn't work, but the guardian didn't notice and pulled the ITMY into nirvana.
 - Also, SRM align didn't lock properly.
I manually aligned the stuff that didn't work, and got the back to full lock.

one unexpected restart.

During the last stretches of full lock,  powers have been remarkably stable, but still showing some residual fluctuation. Here I'm analyzing the correlation of those power fluctuation with residual angular motion. I compute the best linear combination of all the ASC error signals (WFS and QPD) and their squared value, to predict the power fluctuation. The results fit very well the power time variation. One general comment is that the largest contributions to the power fluctuations come from pitch residual motions. The MATLAB code is attached.

AS RF90

The first plot shows the real AS_RF90 power (in blue) and the best fit obtained from the ASC signals (red trace). The second plot is a zoom in time. Using the same algorithm that I developed in the non stationary noise studies, I obtain a ranking of the most relevant ASC signals. The full result in shown in the third figure. The most important channels are AS_B_RF36_I_PIT, AS_A_RF45_I_PIT and REFL_B_DC_PIT.  The first signal is used for SRM, the second one is the other quadrature of the DETM signal (maybe the demodulation phase is not well tuned for DETM?) . One important remark is that most of the dependencies are with the linear channels and not with the squared values, meaning that the actual alignment working point is not the optimal one (in that case one would expect only quadratic dependencies).

AS LF

As above, the plots 4 and 5 show the fit to the power fluctuation. Plot 6 gives the channel ranking. In this case the largest contributions come from: AS_A_RF45_I_PIT^2, AS_A_RF45_Q_PIT and AS_B_RF36_I_PIT.  In this case we have mostly a quadratic contribution, meaning that the alignment is better for this particular port.

POP LF

As above,  plot 7 shows the fit to the power fluctuation. Plot 8 gives the channel ranking. In this case the largest contributions come from POP_A_PIT and AS_B_RF36_PIT. The first channel is highly correlated with the PRM motion, and the second one is used for SRM.

XARM

As above, plot 9 shows the fit to the power fluctuation. Plot 10 gives the channel ranking. The largest contribution is the same as for POP LF: POP_A_PIT. This seems to indicate that most of the power fluctuations in the arms comes from fluctuations in the PRC.

Summary

Tonight we worked on making the ASC more robust, and the signals more decoupled.

Details

We are able to close the same loops as last night (LHO#17124), with the same issues:

1. In order to engage cETM or PR2, these optics must be manually adjusted beforehand to bring the error signals close to zero.
2. The PR2 and PRM loops seem to make the sideband buildups less stable.
3. No matter what loops we close or what optics we touch, we cannot seem to improve the recycling gain (as measured by the arm buildups). Over the last few days, we seem to get about 26 W/W. However, we can seemingly improve the visibility (mainly by adjusting cETM) as seen in LSC-REFL_A_LF. So it seems that we can make more power enter the interferometer, but we cannot get it to circulate in the arms.

The goal for tonight was mainly to try fixing (1) and (2). For (2), Stefan worked on decoupling the POPA → PRM loop by applying a pitch step to PRC1, and then recording the resulting steps in the control signals of INP1, PRC1, PRC2, SRC1, and SRC2. These step sizes (normalized by the step in PRC1) are then put into the output matrix. This gave a noticeable decoupling of the loops.

For (1), we noticed that for every 0.1 µrad step in ETMX (pitch or yaw), PR2 required a step of 0.1 µrad in the same direction. Therefore, we are now experimenting with a new loop: REFLA9I + REFLB9I → ETMX + ETMY + 2×PR2. The factor of 2 was established empirically using the same method as above. The full cETM drive vector is −5.2 for PRM, 2.0 for PR2, 1 for ETMX, 1 for ETMY, −9.5 for SRM, 1.8 for SR2, and −0.15 for IM4, but we have not yet employed it successfully. It causes a very sudden unlock of the interferometer, whose cause we haven't pinned down yet.

Some notes about housekeeping:

1. We rephased REFLA9I and REFLB9I by driving an 8 Hz line into PR2 pitch and putting all of that signal into the I phase.
2. The turning off of the DRMI WFS and the top-stage suspension offloading is now handled in PREP_TR_CARM instead of CARM_ON_TR.

We plugged the LSC-EXTRA_AO_2_EXC output into the excitation 1 of the MC board. In this way we could inject a 100 Hz line (100 counts amplitude) into the laser frequency and check the coupling to the IMC transmitted power.

As described in 17129, we used a script to compute in real time the transfer function from our laser frequency excitation to the IMC transmitted RIN. The attached plot shows that we got the expected linear dependency of the TF on the IMC locking servo. Unfortunately we don't have enough range in the MC offset to go to zero. We need about -15 V to go to zero coupling.

For the moment being, we left the offset adjusted to -10 V. This reduces the coupling of frequency to intensity noise by a factor 2.6

This morning I measured the IMC angular sensing matrix, using the same script we used last night in full lock. The script is attached. I added to the list of signal the IMC transmitted power, just to see how large the coupling to RIN is. It turns out that for all angular lines, there is always good coherence of IMC transmission with all angular lines. This seems to indicate that the IMC is not very well aligned in the present configuration, intoducing an excess of RIN due to input jitter.

I added aline at 20 Hz on MC2_M3_L, amplitude 1000 counts. The line is very well visible in the IMC transmitted power. I used a modified version of my phase tuning script (attached) to plot a time series of the transfer function PSL-ISS_SECONDLOOP_SUM14_REL_OUT_DQ over SUS-MC2_M3_LOCK_L_EXC, which should be zero when the IMC is locked on top of the resonace.

However, as visible in the attached plot (both real and imaginary part of the TF over time, it's ot possible to zero the transfer function, but basically only to rotate the phase. My guess is that the longitudinal actuation has a too large coupling to angles, that in turn generate intensity noise. We should repeat this measurement with a frequency line.

I updated the script to measure a generic sensing matrix, already described in 17085. The script attached to that log entry was using tdssine to generate the excitation: the drawback was that the sine was switched on without any ramp. Today this was causing the DRMI to drop lock.

This new version implements a ramp in and ramp out of the excitation, using awgstream. The usage is the same as the old version:

The script configuration is at the beginning of the python file. One has to set

• the list of excitation channels to be used, the corresponding line frequencies and amplitudes, the duration of each measurement
• the list of error signals (the one you want to include in the sensing matrix, at the "numerator" of the transfer function)
• the list of monitoring channels that are used to measure the motion of the optics (those will be used as the "denominator" in the transfer functions)

When lauched without any command line argument, the script switches on the excitation one at a time (GPS times are saved to a log file for future reference). If you want to reprocess a previous measurment, you can launch the script passing the logfile as a command line argument. In this case the injections will not be performed, only the old data will be reprocessed.

When all line injections are done, the script reads the data from disk and compute the sensing matrix. Basically, it's the value of the transfer function (error signals) / (monitoring channels).

The output is saved to an HTML file that contains three tables:

• the absolute values of the sensing matrix, with the dominant degree of freedom emphasized for each error signal, and not coherent elements grayed out
• the table of coherences
• the sensing matrix with the full complex elements

The attached scripts have been used to measure both pitch and yaw sensing matrices in full lock, DC readout.

Sensing matrices will follow

We've closed the following ASC loops in full lock, both pitch and yaw:

• ASB36Q -> BS
• ASAIR45Q -> dETM
• REFLA9I - REFLB9I -> IM4
• REFLA9I + REFLB9I -> cETM
• REFLA45I -> PR2 [a few 100s of mHz for pitch, ~20 mHz for yaw]
• POPB -> PRM [100-200 mHz for pitch, 50-100 mHz for yaw]
• ASB36I -> SRM [~100 mHz for pitch and yaw]
• ASC -> SR2 [~100 mHz for pitch, <50 mHz for yaw]

The above order is the order in which we turned them on

Turning on PR2 appears to just impress low-frequency seismic motion onto POP18 and ASAIR90. This is somewhat improved by turning on the PRM loop, but POP18 and ASAIR90 remain worse than if no PRC ASC is engaged at all.

To tune the demodulation phase of any R signal, you have to inject a line and typically minimize the line in the Q spectrum and maximize in the I spectrum.

The attached script help in this operation. If you set up the I and Q channel names and the frequency of the line you are injecting, it shows a StripTool like chart showing in real time the ratio of Q over I at the line frequency. You can then move the demodulation phase to bring the ratio to zero. Since what is plotted is the transfer function, it has a sign, so you can rely on the zero crossing.

This script can be easily modified to carry out different tasks, for example

• tuning the longitudinal offset of a cavity (using the transmited power)
• tuning the angular offsets of the IMC, injecting a jitter line and changing the ASC offsets
• ....

Sheila, Gabriele, Stefan, Alexa

Today we managed to close all DRMI ASC loops.

• REFLA9I - REFLB9I --> IM4 (BW: ~100mHz)
• POP A DC -->PRM (BW: ~10mHz)
• REFLA9I --> PR2 (BW: '100mHz)
• ASB36Q --> BS (BW: 3Hz)
• AS_C --> SR2 (BW: ~1mHz)
• ASB36I --> SRM (BW: ~100mHz)

The gain and filter settings are depicted in the first attachment. We also have decoupled AS_C from SRM with an adjustment in the output matrix (see second attachement). The BW are all rough estimates. Both POP A DC (P,Y=-0.03. 0.3) and ASC_C D (P,Y = -0.5, 0.1) have offsets that correspond to good buildups. So far we have been able to close these loops several times even with re-running initial alignment. This is all in the guardian now.
