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:

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)
• Rotation stages behaving better, more measurements when we have beam (Vern)
• BRS are waiting for wind.  ETMx code changes this week (Krishna, Michael)
• Commissioning This Week:  Starting probably wednesday?  
  • Need IMC locked to do alignment on ISCT6.  
  • POP_X work,
  • TCS?(high power, kind of good starting point, fine tuning needed), 
  • 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).

Kyle and I quantified the leak in east door outer o-ring this morning to measure 2.5e-7 Torr-L/s. The leak was found around the 10 o'clock position, which is the location of the "old leak" at a o-ring seal repair region. This leak is small and no need to pull the door for repair. The annulus ion pump will mitigate the leak.

Details about the leak check activity:
Background of leak checker this morning after running all weekend was 6e-9 Torr-L/s.
Calibrated external leak measured 5.5e-8 Torr-L/s.
We sprayed the 2nd quadrant with instrument air while flooding the other quadrants with He. No leaks detected.
Then we taped/sealed the two adjacent notches and flooded the notch in 2nd quadrant with He. Detected a leak and continued to flow He until the leak rate stabilized at 2.5e-7 Torr-L/s.
Then we flowed He to the left and right of the notch. Leak rate decreased and then rose back to 2.5e-7 Torr-L/s as we approached 10 o'clock position. 

We will pump down HAM6 this morning. We expect roughing to take 3-4 hours before we can turn turbo pump on. After we activate turbo we will open GV5&7.

There was a flurry of injection locking relocks this morning.  All were associated with my attempts at
locking the frequency servo.  The relock counter increased from 54 to 78 during the ~1 hour period I
was dabbling with it.  The injection locking electronics needs tweaking.

    The pre-modecleaner servo needs adjusting characterising - to be done later today.

During this period we had some frame writer instabilities. These were not being recorded in the restart reports following the fw upgrade to Ubunutu, this was fixed 3/30.

"New" high voltage cable was pulled yesterday along with new fiber.

The cable was tested yesterday, hi-POT tested up to 5k, then both ends terminated.

Fiber was tested today, all good.

Today the power supply was setup on the shelf and powered on, ion pump is working good thus far.
