TITLE: 01/22 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 111Mpc
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 10mph Gusts, 8mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.39 μm/s

Microseism has been on a downward trend the last ~5hrs.  There are winds but they look to be at or below 10mph.
QUICK SUMMARY:

• Tyler/Chris/Scott are out at MX doing maintenance.  Looks like a clear path to MX.  Gerardo told me last night we are expecting an LN2 delivery to MX (CP6?) sometime today between 8am-5pm.
• H1's been locked over 18.5hrs w/ a range of 116Mpc (about 3Mpc below previous recent locks).
• Continue to have Timing Error RED light on CDS Overview (noted by Cheryl).

snapshot of the H1IOPASC0_GDS_TP.adl (the medm) is attached.

Since the live readback is reasonable, continuing Observe.

(Kyle R, Gerardo M)

In preparation for the replacement of GV20's annulus ion pump, we delivered an aux-cart and components to X-End.

(Gerardo M)

Different items were relocated inside the VEA to allow access to the annulus pipe system, all laser welding safety barriers were moved from one side of the VEA to the other, and the monolithic quad cover was relocated to under one of the cleanrooms.
Crane access to support the annulus pipes was evaluated; a cleanroom is currently covering GV20, to reach and support the annulus pipes a filter will have to be relocated or removed (see photo), still trying to determine how to do that.

This was a Swift alert. LLO was conferred with.

INJ_TRANS Guardian was placed into INJECT_KILL

We went to ISCT6 to align the 1811 that we had installed in the AS air path this morning in the maintence window.  We were able to align onto the diode, there is about 200 uW of 1064 arriving on ISCT6 and about 130uW of that is incident on the diode (which is overfilled with the lens we currently have).  We were able to see the 3.125MHz signal on the RF analyzer, but it is only about 20dB above the noise, and we didn't see any of the interesting features that Daniel and I saw on the OMCDCPD spectrum at these frequencies last week.  

We also attempted to measure a transfer function from the LO loop to this signal demodulated using the HD demod, however the signal is too noisy for us to get any kind of meaningful measurement. 

One thing to note: Before we went to the floor I opened the AS air beam diverter.  I expected that this would take us out of observe.  Corey took us out of observe manually a few seconds later.  I tried to investigate why this didn't take us out, these beam diverter channels are on ECATPLC1 in SDF.  There are only 5 beam diverter channels in SDF, although there are more channels that coming from the beam diverter.  Perhaps we need to update the channel lists used by SDF?

STATE of H1: Commissioning
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 22mph Gusts, 18mph 5min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.55 μm/s
QUICK SUMMARY:

• H1 at NLN
  • Sheila and Camilla in the LVEA at ISCT6 doing commissioning work
    • they just called to request another 30 minutes
  • LLO is currently down
    • spoke to the operator there and they are on their way back up
    • our time request will be fine with them

WP 8384 ScottL, ChrisS & HughR

The South Crossbeam of HAM7 was extracted this morning.  The Crossbeam was held on the Support Tubes & their Jacks while the East HEPI Housing was removed.  The crane was connected to the Crossbeam and lifted off the Support Tubes and translated East.  The Crossbeam then was rested on jacks while the crane pick was shifted from the ends to the middle.  The Crossbeam was then slid sideways ~ 10' so the center pick could be effected.  Then the Crossbeam was lifted off the sliding jacks and craned out of the way.  Certainly this was the most difficult extraction in this subject effort.  The remainder should be much easier.

Attached is an image of the space between HAM 7 & 8 now with the HAM7 S Crossbeam removed.

During Tuesday maintenance Phil and myself tried to replace the Cisco 3560 switch in the CER for a Fiber-store FS S5500-48T8SP, after we migrated all devices plugged on the Cisco switch to the new one, the switch became unstable loosing connectivity and dropping all connections including the optic fiber link to the core switch. After several reviews of the configuration both at the Core and at the local switch was determined that further load test should be done to this new hardware. As a result we rolled back to the Cisco 3560. 

45-day trends for HEPI Pump channels.  All signals look steady/flat.

With a fairly light Maintenance Day, started locking early, and once the LVEA became quiet and network switch work (i.e. cameras) completed, we were able to get back to OBSERVING fairly easily.  Range looks a little lower than the previous locks (hovering at 115 vs 119 Mpc).

Attached are SDF diffs which were all Accepted after being reviewed (for ETMy Test Offsets [known issue noted by Camilla], ITMx/y Noisemon [Sheila's work this morning], & CAL CS [rounding errors]).

I increased the size of some of the labels on H0_VAC_SITE_OVERVIEW_CUSTOM.adl and committed the change to svn. I then regenerated all of the vacuum medm screens from svn. I then regenerated H0_VAC_SITE_OVERVIEW_CUSTOM.ui from H0_VAC_SITE_OVERVIEW_CUSTOM.adl and copied it to nuc22. I then changed the startup script for nuc22 to use caQtDM for the vacuum overview screen instead of medm.

I have written a python script to clear all open testpoints. To run it from the command line:

clear_all_testpoints

It can also be ran from the CDS Overview MEDM screen by pressing the 'ClearTestPoints' button in the lower right corner of the screen.

In both cases, if there are testpoints to be cleared a confirmation message is displayed (see attachment). If confirmed, then the open testpoints are cleared.

Note that the h1calinj model is exempted from this due to hardware injection testpoints.

FAMIS 11527

I think I accidentally put too much water in the TCS Y chiller. I didn't see it do anything abnormal though.

TCS X
Before: 28.9
After: 30.5
Added: 150 mL

TCS Y
Before: 9.3
After: 10.8
Added: 100 mL
