(Eric A., Corey G.)
After the BSC1 cleanroom was engaged we were given the go-ahead to finish the dirty job of roughing the concrete for the HAM12 Piers.  This work was completed around 5:30 (well, almost complete:  I cleaned up most of our mess, but there are quite a few items we need to put away---will leave this for tomorrow).  The floor around HAM12 was sweeped and then wet-mopped.  We also utilized a HEPA fan to help keep our mess to a minimum, and this worked out great (thanks Rick & Eric!).  I will close out our work permit tomorrow when our mess is cleaned up.

Richard and Filiberto started pulling the H2 electronics from the LVEA.

H0:FMC-MX_CY_H2O_PUMPSTAT is failed. See Ski's elog
Sno Valley came to look at the part numbers for the pump.

Keita and Dani started pulling optics from ISCT7.

Rick rigged up a HEPA filter near HAM12 to pull in the dust from the scouring.
Corey and Eric finished the prepping work for the HAM12 pier anchor bolts.

Kyle closed GV1, GV2, GV10 & GV11, started venting the vertex and HAM6.

Gerardo removed the H2-ETMY transmission monitor.

Jodi and Ski prepped for the BSC1 vent and worked on the clean room at mid Y.

Apollo cleaned at Y end.

Cyrus turned tidal off.

John Zweizig started migrating the DMT viewers to the advanced ligo configuration.

Dave removed the disconnect channels from the EDCU.

Reboldt worked at the LSB.

Started pulling optics etc. from ISC 7.

General purpose mounts, beam dumps etc. are restocked in the optics lab cabinets. 

Most of labeled optics are put in boxes and stored in ISC cabinets, some are returned to the optics lab.

The work will continue several days more.

Closed GV10 and GV11 (Ski et al. craning scissor lift over VE).  Note GV11 "clanked" atypically when gate cammed closed.  



Started CS purge air compressor*Closed GV1 and GV2*Started Vertex, XBM and YBM QDP80s and Main turbo pumps*Vented Vertex and HAM6 volumes simultaneously (note: new requirement to maintain <0.5 atm pressure difference across HAM6 septum as the result of design flaw awarness-see Mike Z., Dennis C., John W., Albert L.)*Isolated BSC1 annulus ion pump*removed all but (4) door bolts from BSC1 South door

DCS (LDAS) transitioned to A6 (meaning "After S6") on Oct. 20, 2010, shortly after 8 am local time. During this time period all raw (L0) data at LHO and LLO is being copied to the site LDAS archives, and also is being transferred to the CIT LDAS archive, whenever this data is available from any of the DAQ (CDS) framewriters. The same holds for second-trend and minute-trend data. We continue to rsync any new DMT data, whenever it is available, but no LDAS RDS data is being generated during this time period.

Note that the raw (L0) data will soon be pared down to mostly PEM data, and there will be no interferometer data until squeezing data and aLIGO test data begins to be written to the raw frames. 

Thus, if you are looking for data "After S6" outside of the control room, ask about A6 data.

Reset all Top Mass flag magnets on Quad-2 to conform to Derek’s document E1000617. Set the Gains in MEDM to conform to Mark’s document E1000494. Ran Actuator Sign Test and all responses were positive.

Removed transmission monitor and components, including green pier.
Components are stored inside the VEA, they will be removed in the near future.

Cables were removed last week, see here.

The polarities appear to be 180 deg out of phase from Derek's poster cheat sheet E1000617.
Jeff is going to go switch all magnets and then reset the servo gain signs.  Hopefully this will then match the poster.

Had transient low value for the instrument air pressure at the Y-end station this morning.  No recent history or trend -> probably due to users activity.

The instrument air pressure briefly alarmed, Kyle has been notified:
22-Oct-2010 10:17:34 : HVE-EY:INSTAIR_PT499         LOW          MAJOR            59

Apollo finished cleaning in the LVEA

The crane inspections in the LVEA are completed

The crane training class was held this morning

Cheryl and Aidan continued TCS decommissioning
Cheryl turned the clean rooms on in the LVEA

Corey and Eric continued drilling holes at HAM 12

Gerardo, Cyrus and Jodi worked on the clean rooms at mid Y

Reboldt came to work at end Y

The Genie lift was moved to end Y, Apollo will probably begin cleaning there next week

Finished removal of optical lever power supplies, removed the power supply for ETMX and ETMY.
Power supplies are stored on the racks of receiving/storage area of the LSB.

(Eric A., Corey G.)
All the holes have been drilled (15 today.  It took one $200 Hilti drill bit to get through about 14 holes--that steel rebar is a pain!).

Eric will clean out the holes, check their depths, and cover them with tape.  The vinyl-ish flooring has been removed.  The final thing we would like to do is rough the concrete for the grouting--will try to do this Monday, time permitting.

  Still have a glitch in the Main Chain right channel in satellite box 3200715. We have eliminated cables and OSEM as the problem source. Swapped SB 3200715 and SB 320078 and problem stayed on MO Rt. Moved cables back to original position.
 
  We swapped cables on the AA channel and the AI channel. Glitch moved from MO Rt to MO F1; possible problem in the AA or AI chassis. Filiberto is going to do some more testing this afternoon to determine which chassis is at fault.      

I've started 3 clean rooms in the LVEA to counteract the dust from cleaning, and get the area ready for vents next week.  HAM3, HAM8, and HAM6 clean rooms are ON.  The clean room over HAM1 needs to have the large switch at the top of the clean room moved to the ON position, before it can be started.  

Turned off the robofom and roboscimon cron jobs on script1 and control100.

Fix problem with suspension test stand workstation (suswork1) where it is unable to access files for burt restore.  Found that burt's .snap files are stored in bscteststand:/data/autoburt/ which was not accessible on suswork1.  Did the following:

Modify bscteststand computer to export /data for nfs mounting on suswork1

Modify suswork1 to mount bscteststand:/data on /data

Verify that burtgooey on suswork1 can access .snap files on /data
