After Mark posted the MC1 and MC3 plots today (

http://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=4888), I went in and immediately found the offenders - all 4 of the horribly trapped blade tip stops on the intermediate mass were touching.  I sepent some time trying to free them to no avail and decided to come find Cheryl before proceeding and likely misaligning various targets around the HAM2 table.  We agreed that I will disassemble the top 3 BOSEMs and flag mounts to free up the screws in the morning.  IO will then need to realign MC1 and we'll re-run TFs.  An inspection of the same MC3 screws showed they were not touching the blades although were not all necessarily at the spec 0.75mm gap setting (hence the clean TFs there).

The AC unit in the H1 diode room has been cycling off an on about every 50 minutes resulting in a 5 degree temperature swing in the room, from 70 F to 65 F. This may be due to the system being underloaded, and the minimum amount of cooling the unit can supply is pushing the room to 65 F before it turns back off. This unit ties into the AC units in the H1 electronics room, half of which happened to be off. Yesterday Richard brought them back up, and this appears to have created enough of a load on the system to keep the diode room a little more stable, but it still is experiencing temperature swings.

The vacuum brush was retrieved from clean and bake this morning so that first vacuum could begin. First vacuum was completed and the floor replaced. Wipe down was started.

Two cleanings of the chamber and cleanroom took place this morning. The garbing/staging cleanroom was removed from the e-module and placed near HAM9. The door was removed from the chamber this afternoon and the g/s cleanroom re-located to the west side of the chamber cleanroom.

The CDI (contamination/dust investigation) kit arrived today. As required by procedure E1201096-v3, a couple of items were taken to clean and bake. They should be ready tomorrow morning.

Today, we removed the stays which were blocking access to the needed BS BOSEM tablecloth adjustments.  We then reset all of the OLV OSEMINF settings (burt snap good for the hour following this entry, or see attached snapshots).  The filtering still needs some work apparently.

The side BOSEM measured quite low so was swapped out with S/N 438.

All BOSEMs were set to 50% OLV.

(This work was mostly done Friday 12/7 but I wanted to check a few things before posting.) 

After the M3UL OSEM was sorted out (see 4840), I went on to get all the matrices and settings checked out and the damping working. I ran prepare.m to be sure all the filters were loaded. I entered all the M1/M2/M3 OSEM2EUL and EUL2OSEM values from the output of make_sushlts_projections.m. I set SENSALIGN and DRIVEALIGN to the identity matrix. I set the signs in M1 COILOUTF to give +ve sensor response for +ve offset. The final values were -1, -1, +1, +1, -1, +1. This agrees with the settings previously used on the triples test stand but differs in SD from E1100109-v2. I set the signs in M2 and M3 COILOUTF per E1100109-v2. I found by trial and error a set of damping gains that gave stable damping, but these can probably be improved: -0.5, -2, -1, -0.02, -0.01, -0.04.

This report is for yesterday, 12/10/2012.

Justin reported that all the dust monitors in the LVEA were suddenly reading INVALID. I looked at the IOC running on h0epics2 and it was reporting errors. Restarting the IOC did not fix the problem. I went out and power cycled the Comtrol in the LVEA. Restarting the IOC again after this brought them back.

There will be gaps in time for this day that can not be trended, due to the values being set to NAN when the code was restarted. Plots in dataviewer for the counts will have to use times that do not include these gaps.

Kyle 
Opened GV1 (12/10/2012) 

Kyle, Gerardo 
Opened 2.5" and 1.5" metal angle valves on BSC3 dome -> Began pumping the combined volumes of the YBM and the Vertex (minus HAM1, 2 and 3).

The South East corner of BSC 9 had the HEPI housing installed incorrectly causing the foot to have insufficient clearance around several points. The bolts had been over-torqued and/or the tapped holes had chips and one bolt galled. A sawzall was used to chop through the bolt, and then a drill was used to remove the rest. After retapping the hole ~75% of the threads remained, which should be sufficient for only a 45ft-lb torque. Additional holes had to be drilled and tapped to allow the clamps to be used with the new housing position. The housing was reinstalled and the support tube should be within a couple thousandths of where it was originally sited in.

The HAM cleanroom was moved over HAM9 yesterday in preparation for an incursion. The cleaning crew will try to get cleanings done so that the door can be removed today. A garbing staging cleanroom will be moved into place ASAP. Robert, Cheryl and I are tentatively planning on an inspection tomorrow.

This report is for Monday, 10 Dec 2012.
Brushing of the floor and all hand work complete. The crew was pulled off to work on other things and to await some tooling from Clean and Bake.

This report is for Monday, 10 Dec 2012.
The dome bolts were torqued down in the morning and the door was returned to the chamber in the afternoon. Door bolts will be torqued today.

We finished installing and aligning the H1 ITMY optical lever and measured the beam profile.

Parameters of the laser are listed below, this data was measured in-situ using Thorlabs BP109-VIS: 

Gaussian_Fit_X = 97.46%
Gaussian_Fit_Y = 97.66%

2w_X = 4.06 [mm]
2w_Y = 4.05 [mm]
Requirements = 4mm

Starting DTT TFs on MC1 and MC3, in parallel.

Joe Gleason, Luke Williams, Cheryl Vorvick

Location: HAM 2

We've aligned turning mirrors RH5-6 which steer the PRC MM MON and MC TRANS MON beams to IOT2. We've set the beam separation such that these beams converge at the location of the IOT2 upper periscope mirror.

•	PSL diode room temperatures continuing to fluctuate between 65F and 70F, producing alarms. This has been an ongoing issue since 6DEC. Michael R has 
        made adjustments to the heating units for the room and this should help.

•	0700 Work is ongoing in and around BSC1. Bolts on the dome flange were torqued first thing this morning by Apollo---tripped ITMY SUS watchdogs.

•	0930 Kyle opening GV-1

•	1100 Travis S et al removing First Contact from ITMY---unsurprising SUS watchdog trips.

•	1300 Thomas V and Jax S working on optical lever alignment in LVEA.

•	1330 Bubba craning cleanroom over HAM9 to prep for MC tube inspection.

•	1450 Dave B and Jim B to MX.

•	1500 All LVEA dust monitors went INVALID---Patrick was investigating.

Received word from Bubba that the doors were on BSC1 and personnel were clear, so will be taking TFs on both chains of ITMy from now.
