We installed the ASC IMC model on h1asc0 front end for the first time yesterday (Tuesday). This model is a copy of LLO's latest model in svn, converted from L1 to H1. Wednesday we will re-attach the ASC to the Dolphin Fabric, add the ASC Pitch and Yaw control inputs to the MC1,2,3 Suspension models and add the ASC to the DAQ. We also need to copy LLO's filter module, safe.snap and latest MEDM screens.

The h1ascimc model required a new QPD common model in isc/common/models. This file is used by the Suspensions systems, so we verified that the change did not change the main QPD part but added new QPD-with-whitening parts not used by suspensions. However we think the h1iscey model may need rebuilding.

Gate valve 18 was soft closed at 3:58PM and open again at 5:45PM

Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot from approximately 6 PM Jan. 14 to 6 PM Jan. 15. Also attached are plots of the modes to show when they were running/acquiring data. The dust monitor at location 15 should probably be replaced. It has alarmed a number of times with a calibration failure.

Got corner4 (NE) HEPI L4Cs leveled today.  Again aggregate motion is very small; no translation or rotation larger than 0.001" or 0.02mrad.

WHAM2 HEPI is ***UNLOCKED***

Filiberto pulling cables to IOT2L.
Corey to end Y to look at ALS table enclosure.
Tumbleweed bailing between mid X and corner station.
Jim B. to mid X to connect PEM channels.
Mid X PEM model built and started. Channels not added to DAQ (waiting on channel names).
ASC IMC model built and started. Channels not added to DAQ (waiting on check of data).
Apollo to move clean room from BSC5 to A-1E adapter spool for mounting viewports.
Apollo to move north side of BSC1 work platform away from the chamber to facilitate SEI work on support tubes.
Reverse Osmosis alarm.
Dust monitor 15 calibration failure alarms.

11:00 Hugh to work on HAM2 HEPI L4C leveling.
16:00 Rai soft closing GV18 for RGA measurements, plan to reopen around 17:00.

The h1pemmx computer has been started with models to collect mid-x seismometer, vault seismometer, and vault magnetometer data.  As soon as channel names are decided, the channels will be acquired.

Travis reports that he found some blade stops touching on the BS, so I'm starting another round of DTT TFs for the BS.

Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot from approximately 6 PM Jan. 13 to 6 PM Jan. 14. Also attached are plots of the modes to show when they were running/acquiring data.

The HEPI was unlocked, Corner 1 relocked, Horizontal Actuator disconnected etc, L4C Leveled.  Reassembled, Vertical L4C leveled, Corner 1 unlocked & positioned checked.
Upon first unlock, lock stress unloads and IPSs read larger numbers.  But in aggregate they tend to counter act one another and motion is very small: 0.0006" +X, 0.0018" +Y & 10urad.
After completing the job however, Corner 1 Horizontal IPS is possibly a bogus number since that Actuator was disconnected.  If I ignore that possibility though, the motion is still pretty small: 0.0019" +X, 0.0008" +Y & 32urad.  Dang those numbers look too good, I better check my spreadsheet eh!

I left HEPI ***UNLOCKED***

Jim and Dave.

We borrowed the modified One Stop card from x1fe3 and installed it into h1asc0's chassis. We started the front end and ran the h1iopasc0 model. 

As an aside, we found that x1psl0 had a non-modified One Stop card, it has been shipped to CIT for upgraded.

• Ken working at end stations installing plastic hose for cables
• Cable installation work on IOT1
• Hugh working on L4Cs by HAM2. The light pipe shutter was closed for this work, making the area laser safe
• Dave and Jim working on rebuilding SEI models
• Cheryl increased the power into the beam tube to 210mW

I adjusted the power in the IO path in the PSL to be 1.1W in front of IO_MB_M3.  The power incident on the top periscope mirror is 210mW.  This increase is necessary to align beams on IOT1/IOT2L...

I generated new EPICS database files with Daniel's updated parser. This splits the databases into separate files for input records and input/output records. It also splits the records into multiple files to limit the number of records in each. This was necessary because too many channels would keep the EPICS OPC gateway from running. We can also now scan the input and input/output records at different rates. I quit the EPICS OPC gateways that were running, and started new ones for these databases. There are now 17 instances of the EPICS OPC gateway running on h1ecatc1. This seems to allow more channels to connect, but I'm not sure how much it will help performance. As more instances are running they take longer to start up. We may have to try spreading the processes over multiple cores, but I don't believe there is currently a way to have this done automatically.

Installation of feedthroughs/blanks on BSC5/BSC9 was completed.
Assembly of TMS Lab cleanrooms got started.

Travis has corrected an EQ stop on the BS (see 5096), so I'm commencing DTT TFs.

Hugo rebuilt the h1hpiham1 model to use the one working ADC on this system (ADC card 0). We restarted the IOP model h1iopseih16, it had glitched earlier today. Both IOP and HAM1 models were added to the DAQ.

Currently the h1seih16 front end is not connected to the Dolphin fabric. There is no need for IPC currently on HEPI HAM1, so we will keep this off the Dolphin network until the ADC problem is resolved.

I did some TFs on the BS using DTT:

/ligo/svncommon/SusSVN/sus/trunk/BSFM/H1/BSTST/SAGM1/Data/2013-01-11_1230_H1SUSBSTST_M1_*_WhiteNoise.xml

It's pretty sick - L and Y are not to bad, but R, T, V and P are nothing like what they're supposed to be.

IAS has given me numbers.  I am unable to move HEPI the requested amount (8mm -X) until the East side Caging Brace Front Faces are moved (removed).  Hopefully we'll be able to reinstall these which allows the HEPI to be locked.  Once this is done we can attempt the translation East.  I believe there is room otherwise for this move.  Caveat: The Actuators are not attached; they have interferences that are not directly determinable now.
For the record, contrary to many statements from SEI to date, BSC1 has only been marginally locked if it can be said it was locked at all.  Most lock bolts were not engaged and only a few of the 40 were doing anything.
