STATE Of H1: Observing

LOCK DURATION:

SUPPORT: Mike L., Sheila, Robert

INCOMING OPERATOR: Jeff B.

Activity log:

18:24 Kyle and Gerardo are going out to MY to turn on pumps they’re using for leak checking. This activity was cleared with Mike L. They are to aLog the pump start time as accurately as they can.

18:40 Pumps at MY turned on

18:50 Kyle and Gerardo back to Corner station

20:14 Kyle and Gerardo driving back out to MY

21:00  Joe B called on TS to let us know that Livingston would be coming out of Scence mode fo commissioning work

21:05 Mike Landry called to give the green light on any testing anyone would like to do as Livingston has dropped out of Science Mode

21:14  Richard out to the roof to assist Robert in PEM work

21:30 Richard leaving the roof

21:43  IFO in to commissioning mode

21:42 Robert and Mitchell outside to do PEM injections

22:30 IFO back to Observing

22:39 Loud thump from Fil closing up the CR floor.

22:40 GAMMA RAY BURST alarm

Shift Summary: Landry gave the green light for Richard to connect antenna cables on the roof while in observing mode. Came out of Science mode to do some PEM testing while LLO was out doing some commissioning . Went back into Science mode coincidentally with Livingston at 22:30UTC. Winds had increased to near 40mph for a short while and are now back down to around 15mph. Microseism increased to .5 microns while EQ seismic holds at 2.3 microns. IFO locked at 4.6 Mpc. Gamma Ray burst @ 22:40UTC has us in “Standown” mode for the next hour.

22:30UTC 

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.

21:44UTC

This was ok'd by Mike Landry. He's assisting Robert Schofield with PEM work.

FYI, I have suspended reporting of HWInjReport runs until I can fix the bug that is causing the anomalous absence of RAW and RDS injections.  Once I have that fixed, I will perform a comprehensive run of HWInjReport starting from September 12, 2015 00:00:00 UTC.

Apologies for not giving notice sooner.

We remain in Science mode locked at 72Mpc. Activities are being filtered through Mike Landry via telephone. Kyle and Gerardo have gone to Mid Y to start vacuum pumps for leak hunting. Wind has increased to ≤25mph. Earthquake graph up to .23microns/s. Terramon reported an R-Wave velocity of .25µm from a 5.1 nea New Zealand and then a 5.2 near Chile. This is most likely the reason for the rise. Microseism is up to about .5microns/s. 2.5 hours - glitch free.

The LHO Advanced Ligo CDS web page (https://lhocds.ligo-wa.caltech.edu) has been modified to include screen shots from selected control room wall displays.  Not all displays are included at this time, this is only a preliminary page. The update rate is once per minute.

STATE Of H1: Observing

OUTGOING OPERATOR: Travis

QUICK SUMMARY:IFO in Observation mode ~75 Mpc. All lights in LVEA, PSL and M/E stations are off. Wind is ≤10mph with occassional highr gusts. EQ sei plot is nominal. Microseism plot is elevated to ~.35microns/s. Cheryl had the first 2 hours of my shift as planned.

Many unexpected restarts of h1tw0 due to raid issues. No other restarts. Due to large size, full report in attached file.

HAM4 and HAM5 have had strong glitches for the past several weeks (sorry if I missed this being reported already, I didn't turn it up in a search, we found these by accident). They are sometimes completely not there, but sometimes happening as fast as twice per second! Attached are a slew of plots taken roughly every two days for H1:ISI-HAM4_BLND_GS13RZ_IN1_DQ (but I also see the same in H1:ISI-HAM5_BLND_GS13RZ_IN1_DQ). 

We don't have a good lead on these, but wanted to report. They look an awful lot like what we have seen before when the HWS camera was on, see e.g., 18531. I noticed a note in the log on August 25 "15:54 Elli – Going to Hartman table at HAM4", and I also noticed that the glitches started showing up after a long hiaitus around August 27th. However, if I have my sign correct (0=off) for the camera switch channels, then the HWS cameras in the central station are currently off in O1 running.  

Assuming it's not HWS, we should probably check ISI actuators for DAC glitches or overflows.

Title: 10/9 Owl Shift 7:00-15:00 UTC (0:00-8:00 PST).  All times in UTC.

State of H1: Observing

Shift Summary: Locked for the entire shift in Observing.  Wind and seismic calm.  Several ETMy saturations, none of which correspond to any RF45 glitching (since there was none that I saw).

Incoming operator: TJ

Activity log: None to speak of.  Very quiet night. 

Locked in Observing Mode for the duration of the shift so far.  A few ETMy saturations, but none of them seemed to coincide with any RF45 glitching, as that has been stable.

TITLE: "10/08 [EVE Shift]: 23:00-07:00UTC (16:00-00:00 PDT), all times posted in UTC"

STATE Of H1: Observing at ~80 Mpc for the past 6 hours

SUPPORT: Jenne, Sheila

SHIFT SUMMARY: Few problems when we began to acquire lock. Smooth ride afterward. Wind speed dropped below 10 mph. No big earthquake. Only one ETMY saturation since we acquired lock. RF45 wan't acting up when the verbal alarm went off.

INCOMING OPERATOR: Travis

ACTIVITY LOG:

23:41 LLO delayed observing for another hour. We take sometimes to do some commissioning work.

0:44 Robert to LVEA to turn off stuff. No injection.

00:38 Locked at NOMINAL LOW NOISE

00:55 Cleared off ASCIMC excitation. Switched to Observing.

05:05 GRB Alert

The new rooftop camera is amazing. I can actually see things at night!

We set all quadrant gains of IMC WFSA to [1 1 1 1] from [1, 0.25, 1, 4]. (WFSB was already all 1.)

We also disabled IMCWFS error offsets in servo filters.

After this, we steered IM2 to bring the beam position on IM4 trans back (at first we tried IM3, but it would make the OSEM output to become larger, and they're already close to saturation).

IFO locked after this without any problem.

We haven't done any jitter coupling optimization and I don't know if Robert had time to do it.

Only one ETMY saturation in 4 hours. Wind speed decreasing together with seismic.

Today I was able to remeasure the frequency noise coupling into DARM. I am not finished analyzing the data, but as a preview I am attaching the TF of the IMC VCO to the DCPD sum above 1 kHz. The coupling appears to go like 1/f, or perhaps slightly faster. A 1/f coupling would be consistent with what was found previously (a flat coupling from REFL9I power to DCPD photocurrent).

I was not able to get coherence between my CARM excitation and the IMC VCO below 1 kHz.
