1205 - Praxair at MY
1455 - Squeezer Laser is on

Sheila Dwyer notified the Control Room at ~2:55pm that the laser has been turned on.  Please follow the relevant safety precautions for Squeezer operation until further notice.

Kyle-Installed remaining bolts and torqued BSC7 east door*Closed GV4*Isolated Diagonal Volume from Purge Air*Pumped GV4 gate annulus volume*Pumped to <100 torr XBM with EDP200*Isolated Vertex MTP*Used Vertex QDP80 to continue pumping XBM to 7 torr*Isolated pumps from XBM (will finish tomorrow)*Restored Vertex MTP to continue pumping Vertex volume

Kyle-Finished roughing down HAM6 (had started Friday?

Activities:
HAM 8 & 9  cleaning
move ISCT10 meatlocker to H1 bay for squeezers
move ISCT4 enclosure table  

~9:35 squeezer laser turned on
~12:05 squeezer laser turned OFF

~1:25 – Ski and others begin moving meatlocker and table by ISCT10 and the table under it.


Door Access alarms:
Y-end door alarm
10:05 - east bay emergency egress door

medm alarms:
FMCS - Annulus Ion Pump – periodically

Due to the winter storm weather we are having, the Staging Building temperature dropped over the weekend to 60 deg F.  Both chains rose in height enough that all 4 top OSEMs were near or at 0 OLV.  Resetting temperature controls in the building restored the OSEM/chain alignment as the temperature came back up to ~70 deg F over the last few days.  

Started one or more sets of heaters in out buildings.
Turned heat on in Staging and Warehouse.  Will have to monitor and possibly reprogram thermostat for winter use.
Shut outside air dampers down on Staging building to help maintain temp.
Replaced battery on tractor.
Bailing tumbleweeds still/

I changed the startup script for dataviewer on bscteststand to use 10.11.0.25 for a server instead of "teststand0" which doesn't exist.  

Kyle, Zack, Rodney - Hung BSC7 east door on chamber.  

Kyle - Began pumping Vertex and HAM6 volumes.  

Kyle - Switched Y-end from MTP to Ion pump, spun MTP down, shut-down QDP80

We realigned and balanced Quad 2 after adding weight to the test masses to account for the increase weight of the glass masses. We had to replace the three lower wires on the Main Chain due to stretch. Found the flags for the UI OSEMs need to be installed and run in at least half way to attain proper pitch. We characterized all magnets and checked polarity per E1000617. BOSEMs on the Top mass have been tested for full range function and are set to their mid points. We will start testing the Top Mass BOSEMs on Monday.
 
Notes: 
(1). The blade stop bolts must be run down so the head is below the level of the magnet holder. If not they will interfere with the left and right BOSEM alignment. 
(2). Watch the side magnet and flag, as it is prone to hanging on the BOSEM, causing misalignment. 
(3). Be sure to square and level the Table Cloth before adjusting the BOSEMs. This is especially important for the correct positioning of the left and right BOSEMs. Failure to set the Table Cloth properly can cause the BOSEM to push down on the Top Mass, throwing off the alignment of the other BOSEMs.          

Cheryl removed optics from BSC7
Kyle put door back on BSC7
More squeezer work
Truck jackknifed on Rt. 10

Where it will find a new home in the physics building atrium display case.

The controller, pressure regulators, and other hardware are stored in a plastic box with the legs. Ballast tanks and tripods are on a second pallet. Both pallets are in the 4k PSL bay.

There is now a dust monitor back in the bake room, using the spare I had for testing. I have given it back location #3, and set the location of the one in the control room from #3 to #4.

- Zack, Rodney, Cheryl

Removed weights (140 lbs) and steering mirror from the optics table.  We then removed all of the auxiliary equip. used to remove large optics (lazy susan, lift table).

Final cleanup and storage of equipment will take place after Kyle and crew has put on the door.

We borrowed these devices so far:

Power meter unit 5
ISCT1 viewer
Beam Profiler Photon XYS
SR785
Agilent 4396B
2 oscilloscopes

Since we are going to use them massively in the next weeks, we will keep them in the SQZ area.
If you need them, just let us know.

Mobile location #3 in the LVEA is monitoring the dust beneath the door of BSC7 as of ~9:23 this morning. It was moved from BSC8.

Attached is the full data trend from before the removal of the door to after the end of the LOS removal. The beginning may incorporate time from before the monitor was moved from BSC8.

Key Points:
BSC7 - H2ITMX and H2FMX removed
Squeezer - On! Specific authorization + specific glasses required for entry to squeezer area

Times in PST:
1214 - Zach cuts himself by BSC7, MikeL brings first-aid kit, assess situation.
1320 - CarolB arrives for Betsy
1323 - DEA notifies LHO that Squeezer laser is on, and Squeezer area is in hazard condition.  Normal laser safety eyewear is not sufficient for protection in this area
1350 - Hanford emergency services calls with test message
1502 - Oscar is done bailing tumble-weeds for the day
1715 - OSB Doors Locked

- Jodi, Jim, Patrick, Zack, Rodney, Cheryl

BSC7 large optics removed - H2 ITMX and FMX.  The black glass beam dumps and supports were also removed. 

Tomorrow: remove weights and one steering mirror, and equipment for removing LOS (lazy susan, lift table).

Also:
Evaluated the plan for removing BSC4 (H2 Beam Splitter) structures, and decided that going through HAM9 or HAM10, depending on whichever is available first, would be the safest route to go.
