We removed the septum between ham 3 and bsc 2, wraped in aluminum foil and ameristat, laid on a pallet. The bellows portion of the spool BE-3A was also removed and hard (aluminum) covers installed on both ends of said spool, and placed on a pallet. A aluminum cover was also installed on the rigid portion of BE-3A which is still connected to bsc 2. This spool will be removed tomorrow.

I and Kiwamu disconnected all cable connectors from IOT2L, and cleared the area around the table in preparation for IOT move.

LEXAN covers were put in place on the viewports.

Laser curtains/dividers were put aside in front of the PSL room and are leaning on the west wall.

Things that seemed to be for I/O purpose (labeled containers for IO mirrors, some mirrors and a couple of mirror holders) were put in front of Cheryl's desk.

When moving the table:

1. Do NOT crane it as it would be hazardous, they're not designed for this.  Unlike iLIGO tables, the legs of these are merely held down by claws.

2. One heavy cable bundle is still attached to the table by a zip tie. Break it first.

3. Two ducts are still trapped between the chamber and the table, though the duct clamps are loose. We need to keep these ducts.

We noticed that the OSEMs on the M2 and M3 levels of PR2 were dead. Trending revealed that they had been dead since Tue 1/29. Richard investigated and found that the power to the AA chassis had not been turned back on after the power supply work that day (alog 5300). They're now back on and working.

Betsy and Deepak put the PRM and PR3 M2 and M3 OSEMs into the OL condition and I logged them. The values with corresponding gains and offsets are as follows:

Attached power spectra of MC2 and PR2 from yesterday afternoon Feb 12th, comparing damping on and off. 

(Late Post)

Upgraded remaining 2 C2960 edge switches (sw-lvea-aux1, sw-mech-aux) to IOS 15.0.2SE2.  Upgraded C1142 wireless access points in LVEA and EY to IOS 12.4.25dJA2.  All work completed by 9AM today.

Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot requested from 5 PM Feb. 11 to 5 PM Feb 12. Also attached are plots of the modes to show when they were running/acquiring data.

Data was taken from h1nds1.
9720 seconds worth of data was unavailable on this server

'No data output' errors on some plots

HAM 2,3 volume was done venting this morning
Apollo removed the east door on HAM 3 and the blank on the septum
Filiberto and Vincent changed the connections of the ISI and HEPI cables to the BSC 1 expansion chassis to conform with the drawings for ADC and DAC usage
Richard to end Y to work on access control system
Filiberto moved satellite boxes for BSC1 to newly installed rack
Mark B. started running transfer functions on PR3
Fire department was on site testing alarms
Eric installed valves in the HEPI hydraulic lines
Jim working on BS in test stand in the afternoon
Rick went into the H1 PSL enclosure to investigate temperature fluctuations, turned out to be normal
CDS maintenance work

SEI ITMY: Vincent and Richard. Changed the h1isiitmy and h1hpiitmy models to agree with Ben's drawings. Rearranged the ADC cables at the rear of the IO Chassis as part of this change. WP 3699 is closed.

added h1seib2 to the Dolphin and DAQ networks.

Installed new channel list in the h1broadcast0 dmt data. Restarted DAQ.

Cleaned up the EDCU CDS channels to remove obsolete front ends and add new front ends.

Jim connected h1oaf0, h1lsc0,h1asc0 RFM to the two RFM switches (X and Y arm), this removed the IPC errors on these front ends.

Imported h2susauxb478 as a first release of h1susauxb123 (removed FMX,Y components).

Powered up h1susauxh34 now that the IO Chassis power supply problem was resolved.

Added h1susbs, h1iopsusauxb123, h1susauxb123, h1iopsusauxh34 and h1susauxh34 to the DAQ.

New IOP models (drawing cleanup and adding SVN Id and HeadURL tags) installed into: h1iopseib1, h1iopseib2, h1iopsusauxh34, h1iopsusauxh2, h1iopsusauxb123.

WP3713 remains open as Hugo did not get to loading the new HAM ISI and HPI models. This may be done later this week.

SUS H1-R6 Field Rack was placed between BSC2 and BSC3 by Apollo. Moved SUS SAT Units for ITMY into final rack location. Units had to be powered down and disconnected for pulling and dressing cables into rack. All associated electronics have been reconnected and powered up.

We removed the east door on ham 3 and then removed the blank on the septum. The door was then replaced on the ham with 4 bolts. All but 4 bolts on the BE-3A spool have been removed and those remaining 4 were backed off 1 turn in preperation for removal of septum and spool tomorrow. 

Deepak and Bubba report they're done for the day, so commencing Matlab TFs on PR3.

Run Cat. 5e cable for HEPI pump controller in Mechanical room mezzanine. Connect pump controller to network switch, reconfigure network settings in the pump controller to connect to the slow controls network.  Controller was NOT rebooted or restarted during this reconfigure.

Rename pump controller to h1hpipumpctrll0, modify user accounts to conform to CDS system.  Mount /opt/rtcds, /opt/rtapps, and /opt/cdscfg directories from h1boot to the pump controller.

For x1dc0, removed the 3 slot PCIe riser card, installed a 4 slot PCIe riser.  Installed 3 10GE fiber cards, 1 IRIG-B card.  2 of the 10GE cards are configured for mx communication to the x1daq switch to allow testing of daqd software on multiple paths.  The x1daq switch is configured for 1 vlan for both 10GE fibers and all the front end computers.  Through experimentation, the following order of cards has been determined:

(top to bottom)

10GE mx :0
10GE eth2
10GE mx :1
IRIG-B

Also restarted x1nds0, wouldn't allow ssh login.

Did B&K hammer measurements on Friday feb 8th on the BeamSplitter that will be installed in BSC2. 
Config: BSC-ISI Unlocked, QUAD Unlocked, Baffles ON, Vibration Absorbers ON, Damping ON.

Attached, pictures describing the position of hammer impacts, and accelerometer + corresponding pulse files.

Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot requested from 5 PM Feb. 10 to 5 PM Feb 11. Also attached are plots of the modes to show when they were running/acquiring data.

Data was taken from h1nds0.

Dan M investigated the MSR SATABOY failure which occured at 15:23 Sunday afternoon. The system was performing a weekly maintenance task and crashed, it is a mystery why this happed this weekend. He took opportunity of the stopped system to perform the same firmware upgrades on the Sun box h1ldasgw1 as he did with h1ldasgw0 last week. The h1fw0 system is back up and running.

We noticed a mismatch in min trend saving periods, 60 mins for h1fw1 and only 30 mins for h1fw0. I changed h1fw0 to use 60 mins which will be applied on the next daq restart.

With the help of Gerardo 1 and 2, and Deepak, we used the ergo arm to stuff the PR3 optic into the suspension.  We then suspended the mass, adjusting roll and height to within the 1mm tolerance and 1mm.  Official height numbers coming shortly.  Deepak will tweek the top stage BOSEMs into center tomorrow and then we're ready for Phase 2b TFs.

Viton pads are usually set under the balancing masses of the HAM-ISIs in order to damp resonances at high frequencies (above 100Hz).

The SEI team would like to asses the improvements that the Viton Pads help achieving. To do so, we decided to have viton pads under the balancing masses of the ISIs of LLO's IMC, and to try without those pads here at LHO.

Transfer functions were measured ovenight on LHO HAM3-ISI. We compared those transfer functions with the ones measured at LLO under an equivalent state:

• ISI is in vacuum
• MC2/PR2 are installed and damped
• TMDs are intalled on the ISI
• HEPI is locked

Comparative plots are attached.
