Ski, Kyle, Hugh - Craned forklift over XBM.  

Kyle, Ski, Travis, Andres, Betsy, Cheryl, Patrick, Hugh - Removed HAM2 East Door then rehung following Cheryl's in-chamber work.  Removed HAM3 East Door and rehung following Cheryl's in-chamber work.  

Kyle - Started Y-mid purge air compressors.  

The LHO X1 SEI test stand had some unusual parameters this morning. I was not able to isolate the table with older Robust Control filters, even with just putting a 0.1 gain on the controller.  I noticed the un-filtered geophone channels nearly saturating.  To be safe, I rebooted the frontend code, but the problem remained. 

I then checked the damping loops - they were engaged.  However, the gains on the outputs were set to 1.  I thought this was the nominal value until I tried to un-damp, then re-damp the table - no success.  The actuators saturated immediately, tripping the watchdog.  So, I then tried a negative gain and ramping from -0.1 to -1 - success.  I had forgotten the gains on the Damping loop outputs were negative -1, while all other loops have positive gains.

After this, control loops were still unstable, tripping the Displacement sensors.  I noticed the Blend filters were off, and then after enabling, the robust control filters isolated the table.

I am not aware as to how (or why) the values were changed in the medm, but the Damping outputs have been at +1 since Oct 21. The watchdog was on the brink of tripping with the +1 gain.  They seem stable now with the negative gain - geophone channels are at safe levels and isolation is on.

Did not succeed. For some reason my compiles are deleting the object files and then complaining that they're gone. I don't know what is going on, so I copied the old code back for now. I restarted everything except the motor controllers, since we are not using them for awhile.

MMT2, MC2, and RM are on earthquake stops.  I used both front and back stops for the small optics, and the South side stops on the RM (opposite the elliptical baffle).

Everyone involved: Cheryl, Betsy, Patrick, Kyle, Ski, Travis, Andres

Big thing today was removal of HAM 2 and 3 doors, EQ stops screwed in on MMT2, MC2, and RM. Doors are back on.
Dave removed H2 channels from the DAQ and several H1 channels as well. 
Patrick is working on several IOCs, which are currently disconnected
TCS enclosures were disconnected from the laser safety network, Dani is aware of this
Dani removing optics from ISCT10, finished today
Cleaning at MY and EY
Apollo at EX
More cable pulling from Filiberto/Cyrus

alog had a possible authentication error over the past
20mins. I restarted the httpd process and it seems
to be ok now, but not sure if the restart really
fixed it.

As part of the H2 deinstall and the H1 mothballing, I am removing channels from the iligo
frames when they contain no useful information. We are doing this to reduce the frame size,
which saves on LDAS tape costs and increases our local data lookback period.

I removed disconnected chans plus all H2 chans from H0EDCU.ini

I edited the fb0c master file and removed many inifiles.

svn versions: 174 = end of S6
177 = today's version

I have turned off two stages of heat in the LVEA. With lights and cleanrooms operating we should be able to get by without these.

The seismic SVN repository has been moved to Kerberos access control, with the new location being: https://svn.ligo.caltech.edu/svn/seismic.  (The previous site was https://svn-private.ligo.caltech.edu/repositories/seismic)

Instead of wiping away the old directory and checking out the entire new one, I simply switched the site the SVN uses to update its local copy.  I switched the site for the LHO CDS "controls" account (in the control room) and the X1 SEI Workstation copies.

On the X1 SEI workstation, the repository local path is still the same:
'/opt/svncommon/seisvn/seismic/HAM-ISI/'

And in the Control Room, the "controls" user copy is still located at:
'/hanford2/users/controls/isi_local_files/SVN/seismic/HAM-ISI/'

New user names and passwords are the LIGO.ORG ones.  

On the workstation, here's the command I entered to switch the checkout site:

>> svn switch --relocate https://svn-private.ligo.caltech.edu/repositories/seismic/HAM-ISI/ https://svn.ligo.caltech.edu/svn/seismic/HAM-ISI/ --username jeffrey.garcia@LIGO.ORG

*entered in the '~/seismic/HAM-ISI/' directory.
 

Kyle, Ski - removed BSC1 south door.  Rehung a few hours later.  

Kyle - Removed all but (4) door bolts from HAM2 and HAM3 East doors (Note-dropped large wrench from top of HAM3 and it hit cross beam)

We moved to ISCT10.

One particularly dirty lens that was just sitting on top of a small aluminum table  OUTSIDE of ISCT10 enclosure along with viewers and such (not used for anything, but who'd put a lens OUTSIDE of the table enclosure?) was thrown away. Finger print and scratches all over.

At some stage all the lights of the card reader went out. This was found by me later when I tried to swipe out of ISCT10, I called the control room, and Jonathan Berliner found that ISCT10 was "offline", whatever that means. 

LSO (Dani) reset my card so I was able to continue working, but ISCT10 is still "offline". Did somebody cut off the power to the access system for this table?

Pacific Daylight Time:
1227 - Done at BSC1,2,3
1234 - Cheryl returns to BSC2 with Patrick for ~15 minutes of checks 
1248 - EY cryopump alarms
1254 - Illuminator lights turned off via MEDM, power supply in LVEA left on
1317 - Dale out to H1 PSL to position camera for LaserFest recording
1330 - Gerardo out to LVEA to talk to Filiberto
1342 - Door Forced at EX (card APB, i addressed it) and at LVEA
1345 - DEA reports ISCT7 done
1347 - Gerardo out
1352 - Dale reports loud noise in LVEA due to microphone feedback from speaker.  He is also concerned for people who may complain about RF interference with other people's work.
1436 - Jodi and Kyle moving engine hoist from EX to MY
1445 - Betsy goes out to HAM1-3 to prepare cleanrooms for door removal
1511 - Corey opens Large Equipment Access Door.
1520 - Patrick out to LVEA to find Cheryl
1528 - Michael Rodruck back to LVEA for more measurements.
1609 - Jodi ook Optics Cart, straddle lift, and CP Stat foil dispenser from LVEA to MY, and is now back
1610 - Apollo guys finish replacing beam tube curtains...will commence crane-cleaning at 7:30am.

Addenda:
- I tried following up with as many Door Forced alarms as possible, but was successful less than 10% of the time in reaching the culprits by phone.  They will not be recorded in my future logs.  Currently, WAPAC reads Off-line for LVEA, but people report that it works.
- Ignore all ion pump alarms.

Mark Barton and I are continuing testing of Quad 2 and developing the testing procedures. Tests look good for main chain. However, there are some issues with the reaction chain, which we will continue working on tomorrow. 

Removal of H2 Electronics from LVEA continues.

Just saying.

Locked down ITMX, ITMY, and BS.  ITMX and ITMY have eLigo glass earthquake (EQ) stops - BS has iLigo viton EQ stops.

On ITMs I used the four EQ stops on the face of the optic to push it onto the back EQ stops, securing it without having to remove the elliptical baffle, or working near OSEMs.  On the BS, I used EQ stops on both sides to secure the optic.

Both ITMs:
All EQ stops showed some evidence of martial removal where the EQ stops contact the optic chamfer.

ITMY: 
When looking at the face of the optic, the Lower Right EQ stop seemed to be very close to the optic.  It's very possible that the venting of the chamber shifted the optic position, so it's unclear if this was the situation under vacuum.

ITMX:
When working with Patrick I turned one EQ stop (LR when looking at the otic face) too far and slightly ground the glass, which could be heard, effectively showing him what not to do.

Contamination:
Evidence of particulate in all BSCs, and HAM3.

Dani and Keita

ISCT7 has been cleared of all optics and other components, excepting the large PDs (which Richard will take), the accelerometers (needs plugs pulled), and a rotation stage (needs plugs pulled).
