Corner Station PEM Upgrades

WP 11121

The following items were completed during today’s maintenance day.

1. Ran BNC cable from PSL-R2 field rack into PSL enclosure
2. Ran BNC cable from PSL-R2 field rack to HAM2
3. Installed Kepco power supply in CER Mezzanine VDD-C5, supply set to 5V
4. Terminated all 7 microphone power cables with CPC connectors
5. Attached pigtail cables (CPC to Micro-B) to power cables, verified 5V output
6. Ran plenum BNC and CAT6 cable from CER to SQZ Bay

Pulling cables from the CER to SQZ Bay took longer than expected. We even enlisted help from VAC group (Gerardo M.) for about an hour. Ran out of time. Following items to be completed next week.

1. Install new conditioning boxes and microphones
2. Connect drive signal to audio amps (Corner and Ends) from PEM AI chassis.

Inlock and OPLEV charge comparison

Although we did not get any inlock charge measurements today, we did get a new value for ETMY last week so I reran my compare code after making some updates to it.

 

If anyone else wants to use it, its located at: /ligo/home/ryan.crouch/Desktop/Charge_measurements/compare.py and you should just be able to run it as a regular python script. The only things one might need to modify in the code would probably be the plotting range at the top if you want to change it from the 6months its set to currently.

IE:

python3 /ligo/home/ryan.crouch/Desktop/Charge_measurements/compare.py

EX PCAL Power Supply Replaced

EX PCAL +24V power supply replaced per WP11162

PCAL EX-V1 U12 PCAL-AOM +24V Kepco supply S1201927 replaced with S1201911 which has an updated BB fan.  Power at supply measured at 24.55V <1A.  Analysis of old supply, the fan bearing completely worn out, will not spin.

h1seib1 (ITMY) down for CER power supply replacement

Jeff, Marc, Corey, Dave:

h1seib1 is down while Marc replaces aging and failing DC power supplies to this CER rack (24V and 18V).

ETMX & ETMY OPLEV charge measurement

This morning I ran the OPLEV charge measurement for both ETMX & ETMY, I only took 3 measurements on each to allow for a DAQ restart.

ETMX's charge is still high (above +/-50V on all DOF) and appears to be trending upwards on UR in both Pitch&Yaw and LL Yaw.

ETMY's charge is lower, it's just at 50V on LL Pitch&Yaw and below on all the other DOFs. There seems to be a slight upward trend on UL & LL over the past 4 months, UR seems stable aside from a slight Pitch incease over the past month.

All the adjusted settings have been restored.

EX Floor Magnetometer Box Swap

I replaced the signal conditioning box for H1:PEM-EX_VEA_FLOOR_X/Y/Z_DQ with one that Fil supplied. The swap was complete at 16:25:00 UTC.

H1 chiXY (Pcal XY comparison factor)

Yesterday, Dripta set the XY comparison correction factors to 1.0 for both the Xend and Yend Pcals.

Last night we had a good 10-hour lock stretch during which we can assess the X/Y comparison factor, chi_XY.

The attached plot shows that it is about 1.0025.

 

Tues Morning Status

TITLE: 05/02 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
CURRENT ENVIRONMENT:
    SEI_ENV state: MAINTENANCE
    Wind: 4mph Gusts, 3mph 5min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.18 μm/s
QUICK SUMMARY:

Delayed post due to the Tues Tidal Wave!!

H1 dropped lock 30-min before 8am, so Betsy started transitioning the LVEA to safe for Maintenance.  (at 241amPT H1 had lockloss and was automatically brought back to NLN/OBSERVING at 417amPDT!)

Workstations rebooted

Workstations were updated and rebooted.

ER15 DQ Shift at LHO - 2023-04-24 to 2023-04-30

Some really nice stretches of observing, thanks LHO! Here are some observations:

• It looks like it's taking a while (~30mins) for noise at certain frequencies to settle once the ifo is locked. Looking at spectrograms there are noise lines around 20-30 Hz, 500 Hz (violin modes), 1000 Hz (harmonics), and broadband noise above 1000 Hz and especially at 5000Hz (laser frequency noise 4-4.5kHz (alog)?).
• PyCBC (e.g. this link) seems to be most affected by random glitches and scattering
• On Sunday the range seems to have a bit of a cyclic trend to it, on the order of 7 hours to go from 130 Mpc, down to 120Mpc and back again. Lasso doesn't show any obvious correlations
• Overflows from ETMX are causing really loud glitches in CALIB-STRAIN. There were 13 of these glitches on sunday. The OMC also seems to be overflowing a decent amount (39 instances of FEC-10_ADC_OVERFLOW_ACC_2_26 on sunday) but these are not showing up in CALIB STRAIN

OPS Evening Shift Summary

TITLE: 05/02 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 137Mpc
SHIFT SUMMARY: Quiet night with first ER15 candiate! 11hours at NLN between 130 and 140MPc range. T
LOG: here was a lightening storm to the East of LIGO 11:15 - 11:45pm.

Out of Observing Time:

• 23:13 - 23:15 due to H1:ISI-GND_BRS_ETMX_HEATCTRLIN change by Jim, Jim changed this so channel is now unmonitored. 
• 23:21 - 23:24 so Dripta could change PCAL channels PCAL{X,Y}_XY_COMPARE_CORR_FACT to monitor overnight alog 69227.
• 00:23 - 00:45 for calibration team changing AWG lines.
• 03:32 - 03:33, 03:26 - 03:37, 04:04 - 04:05 for H1:ALS-X_FIBR_LOCK_TEMPERATURECONTROLS_POLARITY H1:ALS-X_FIBR_LOCK_TEMPERATURECONTROLS_ERRORSIGNAL.
  • Unmonitored these two channels - sdf screenshot. Corey and Keita unmonitored these channels and more in 2016 (alog 32498, FRS 6932). Should we do the same? Tagging ISC. 
  • See attached for ALS X vs Y PLL autolocker comparison, Y appears to be more stable in frequency and polarity doesn't change. 
• 4:55 - 4:56 Camilla reloading RUN_ESD_EXC guardians (alog#69233)
• 7:00 - 7:01 Camilla reloading RUN_ESD_EXC guardians (alog#69234) I let the observation bit automatic guardian take control of this one, it took us in and out twice.

Dan's PI monitor on nuc25 needed restarting twice.
