Transfer functions of the injection locking servo electronics were taken.
The previous measurements from when the PSL underwent acceptance testing
are posted in the DCC under
  https://dcc.ligo.org/DocDB/0100/E1300129/001/tf.pdf
That result listed the unity gain and phase margin as being 2.8 kHz and
57 degrees respectively.

With the previous setting of gain = -1.50V, the unity gain is ~8.5 kHz
with about 40 degrees of phase margin.  Setting the gain to -1.70V, upped
the unity gain to ~10 kHz.  This is consistent with the acceptance test
result from L1, which is in the DCC under
  https://dcc.ligo.org/DocDB/0068/E1100716/006/injection_locking_tf.pdf

Also attached is the oscilloscope image of the injection locking error
signal.

I have generated a C01 and C02 calibration systematic error spectrogram for all of O1.

The spectrogram takes the calibration from every day of O1. The frequency vector goes from 5 to 3000 Hz.
These plots are preliminary because my veto definer files do not veto all bad times, so I still have to hack together some vetoes of my own.  This is mostly a concern for the LHO C01 plots.  This will be resolved ASAP.

The plots have dashed blue lines at Sep 14 2015, Oct 11 2015, and Dec 26 2015.
For reference I have included LHO Dec 26 Uncertainty Budgets for both C01 and C02.  These should correspond to the third dashed blue line in the spectrogram.

Next, once the vetoes are properly applied, I will post revamped systematic error spectrograms alongside Total O1 Uncertainty Budgets.  Without the correct vetoes my Total O1 Budgets are not yet useful.

For the LLO All of O1 Calibration Spectrograms, please see LLO aLOG 25618

01:30 Evan and Craig back from EY

~09:00 Japanese film crew came back to report that they left two cameras on the hill along the Y arm between "4th and 5th door" (door counting from corner station). That's somewhere between corner station and mid Y.

Received HV pump cables and custom length power cords that had been ordered last week -> HAM7, BSC4 and HAM12 annulus pumps started today -> pump carts moved from HAM9 to HAM8 and BSC4 to HAM6. 

Gerardo
Routed and terminated CDS signal cables to HAM7 and HAM12 annulus ion pump controllers

Kyle 
Pumping HAM5/HAM6 annulus volume with pump carts at each pump port -> Energized HAM5 and HAM6 ion pump controllers

Kyle, Chandra

Opened valves that were soft closed a week ago. 
GV 7 needed 40 psig. GV 5 needed 45 psig to open. 

Attached is plot of pressures on either side of each valve before and after opening. Before we realized to pump the gate annulus after a week, we had already set pressure against pistons to 20 psig, shifting gate slightly and releasing annulus gas into beam tube.

The EPICS state code that controls the enabling and disabling of the cold cathode gauges was not installed for the gauges that got added to HAM1 and HAM6 (PT100 and PT110). However, the on/off toggle buttons on the medm screens for these gauges were writing to the state code request channels. This is why toggling these buttons had no effect. I updated the H0VE_LX_Y0.adl and H0VE_LY_X0.adl medm screens to use the channels that output directly to hardware instead of the state code request channels:

request channel        hardware channel
HVE-LY:X0_HSCCONOFF -> HVE-LY:X0_HS100
HVE-LX:Y0_HSCCONOFF -> HVE-LX:Y0_HS110

Pumped down HAM6 from atmosphere to 0.5 Torr in 3 hrs. 
Turned turbo pump ON. It tripped once (overload) after many minutes of spinning up. 
Restarted turbo; it came up to speed in normal time. It felt hot to the touch so we placed a fan near it.

Current HAM6 pressure = 4.5e-5 Torr 

Day's Activities:

• 8:15:  Karen checking out HAM6 area
• 8:49:  Running cables for Access System between HAM1-4; most of the day. (Fil & Ed)

1535 -1350 hrs. local -> To and from Y-mid 

Exhaust check valve bypass opened, LLCV bypass opened 1/2 turn ccw -> LN2 at exhaust in 2 mins 10 secs. (Restored valves to as found)

Next CP3 over-fill to be in < 72 hours.

End X PEM ADC 0 channels 8-13 (starting from 0) have been activated for a PEM test. These channels are already in the science and commissioning frames as H1:PEM-EX_ADC_0_08_OUT_DQ through H1:PEM-EX_ADC_0_13_OUT_DQ at a sample rate of 2048. Until this afternoon, the values were fixed at 0.

At Bryn Pearlstone's suggestion, Weigang Liu has tried folding data
daily/monthly/O1ly from corner station magnetometer channels
beyond the ones reported on previously, where as before, 
data from October 20 (day of unplanned power outage) has been excluded. 

Attached are the summary plots, while links to the daily & monthly plots are here:

H1:PEM−CS_MAG_EBAY_LSCRACK_X_DQ
H1:PEM−CS_MAG_EBAY_LSCRACK_Y_DQ
H1:PEM−CS_MAG_EBAY_LSCRACK_Z_DQ

As before, each figure has a top graph with the raw folded (averaged) data,
a middle graph with the spectrum of the folded data, and a bottom graph
which is the inverse FFT of the lowest 40 Hz. 

These graphs are qualitatively similar to those seen before for some CS magnetometer channels
in that there is a 2-second periodicity with a positive excursion at a 1-second boundary, followed by
a negative excursion at the next 1-second boundary, and there is additional fine structure,
most notably an extra transient seen at the 0.25-second mark in successive 
1-second intervals. In addition, the X channel shows a transient at the 0.5-second mark
of each second, and the Z channel here seems most different in character from
previously examined magnetometer channels. These fine structures are seen throughout O1.

The FAMIS procedure notes the normal operating range for the oplevs is +/- 10urad (but some can still operate normally beyond this).  I'm assuming the count values in dataviewer are in urad.  Attached are the pit, yaw, & sum 7-day trends.

Notes:

• PIT:  ETMx, ETMy, ITMx, & ITMy are beyond the +/- 10urad operating range, and may require re-zeroing soon.
• YAW:  ETMx, ITMx, ITMy, PR3, & HAM2 are beyond the +/- 10urad operating range, and may require re-zeroing soon.
• SUM: Procedure does not give operating range values for SUMs, but just looking at the 7-day trend, the only oddity is that SR3 has an odd 3-day step up.  Could this be blamed on the HAM6 vent nearby?  Looking back 37-days, see a couple of these steps up over the last few weeks.

This closes out FAMIS #4670.

Started rough pump down of HAM6 at 10:48am local time. Dew point of blow down measured -20degC. 

I have terminated the LO inputs to the AS 90 WFS chassis (as well as the cables that normally go to these ports), so that we can see if the dark offsets are more stable without the triplexer.  Later today, I'll swap the terminators to be at the front of the triplexer box, to see if that changes things.

MONDAY MEETING:

General Announcement:  It's always best to provide data in alogs.  If you have a long entry, perhaps the bulk of this should be entered as a document in the DCC. (Vern)

SEI:  All vibration absorbers installed, and B&K measurements look good!  ISC (i.e. Evan) tested ISC items such as shutters. (Jim)

PSL:  Summary given for work from last week and HPO work continues this week. (Jason)

VAC:  5pm fri & doors on.  GV5&7 opening hopefully this afternoon (Chandra)

Miscellaneous:  

• Japanese film crew setting up camera along arm(s) for time lapse video (Keita)
• Shaker moved during HAM6 Door install (& returned) (Kyle)
• Went over Work Permits
• Reminded everyone about posting work permits for Maintenance Tuesday

COMMISSIONING MEETING

• High freq HAM6 measurments still needed (Robert)
• PSL:  survey tweaking; hard to know how long will take to complete HPO work (currently have 30W going into PMC & 27W coming out).  More tweaking today and possibly tomorrow during Maintenance.
• ISS feedback work tomorrow for Mainteance (Kiwamu)
• Engaging ETM oplevs (in addition to ITM oplevs) (Kiwamu)

  • ASC? (squashing power isolation),
  • Cavity pole....
  • General locking

Jim B. notified me that the uptime for all of the PLCs on h1ecatx1 stopped updating last Thursday. Their time on the CDS overview is frozen at 7 2 45 1 (D HH MM SS). Logging on to h1ecatx1 it appears that the IOC has crashed (screenshot attached).
