I have updated the dust monitor code as per workpermit 3531. This is an update of the code that was being tested here. It is checked into the projects subversion repository under revision 2130. The primary purpose was to fix some communication errors. It is now the version that is running.

We spent today removing the last of the H2 front ends from the LVEA and moving them over to H1.

The H2 front ends h2susb478, h2susb78, h2susauxb478, h2seib8 were powered down (h2tcsl0 having been already removed from H2). Jim rerouted the fibre connection to the FE and DAQ switches in the LVEA to the H1 switches in the MSR via the H2 EE building patch panel. These switches were then reconfigured to serve H1 VLANS. DHCP and DNS changes to boot the three frontends to support the Test Stands.

The IOP models were transitioned from H2 to H1, and the front ends were booted in the new H1 guises.

The ITMY system is now called QUADTST, the FMY system is now called BSTST.

The user models were transitioned, both for IFO (H2 to H1) and for OPTIC (ITMY,FMY to QUADTST,BSTST). Most Dolphin IPC were removed from the models, with the exception of the SUS WD status to the ISI, and the IOP Watchdog system.

The safe.snap files for these models were changed to H1 (Vincent did ISI). All the filterfiles were changed to H1 (Vincent did ISI).

MEDM screens were changed, links from sitemaps were changed.

Old system were removed from H2DAQ and added to H1DAQ. H1DAQ frame size increased from 182MB to 203GB.

simulink webview was changed to only show H1 models.

the old h2susauxb478 will not be powered back up and will not be part of the H1 system.

The ITMY optical lever which was temporarily connected to h2susb478 needs to be cabled to the H1 EE room.

The welder has completed the welding required in the HAM3 cleanroom.  There is still welding to do just north at the south end of BSC2 but that is outside the cleanroom.  Heading south the plumbing goes a few feet south of the HAM3 cleanroom.  A couple more lengths of main line and then we'll be wanting to get into the HAM2/1 area.

Since H2 has gone away in CDS, I shutdown the H2 conlog EPICS client at ~ 4:15 PM. The medm was reporting ~ -97 monitored channels and a few thousand unmonitored channels, which is a bug that needs to be investigated. The web server for recorded data should still be available.

The Romer Arm was moved at HAM2.

Dave started decommissioning of H2 CDS (think he's almost done).

Hugo ran quiet measurements for HAM3 ISI

FMCS alarmed at MX a few times (Ski mentioned this would happen)

Dust Alarms near BSC4 & HAM2 throughout the day.  They were quick peaks and not too high.

Eric A. installed electronics brackets for HEPI at HAM3.

Contractors:  Praxair, Unifirst, Ace Key & Lock

Since there are no more front end computers running h2 models, all workstations in the control room, LVEA, and End Y have been set up for h1 only.

Yesterday, I finished adding dog clamps that did not interfere with the MC1/MC3 cookie cutter.  I also removed the install arms form MC1 in prep for use on MC3.  I started laying out the cables, but have not yet plugged any in - MC3 is being tested now and hogging the shared MC3/MC1 satellite box, so any testing of MC1 will need to wait until the twins are both installed and the cabling is finalized.  The suspension is still clamped and optic caps on.

Attached are plots are dust counts > .3 microns and > .5 microns in particles per cubic foot for Monday Novemeber 5, 2012. The data was taken from approximately 6 AM to 6 PM.

Yesterday we made some preliminary tests of the HAM AUX suspensions in the HAM2 chamber. We released the earthquake stops and checked that we could read sensible data from the OSEMs, and actuate the mirrors too - all of them looked fine, so the questionable cable connection mentioned in entry 4593 doesn't appear to be a problem. We then put the earthquake stops back in place and moved the HAM AUXs into the middle of the table to keep them out of the way for the moment (since we don't have dog-clamps to hold them down). We pulled the OSEMs out to make open light measurements (see comment from Giacomo in the near future). At first glance these look fine.

I ran my spectra with the purge air off. I don't need quiet time anymore.

After the initial install of h1oaf0 we noticed that the RFM Y arm IPC error was lit and would not reset. At 17:28 I restarted h1iopoaf0 with the pciRfm=1 to see if this made any difference, it didn't the IPC error is still stuck on. The model h1peml0 was restarted in the course of this work at 17:28 local time.

WP#3535

modified IOP model h1iopsush2a to move the DACKILL trigger from MC1 to MC3. Prompted by disconnecting the top OSEM cables from MC1 and attaching to MC3 as it undergoes chamber side testing.

This is a transitory WP, so it has been closed.

Removed 4.5" ISC-REFL TIP/TILT 1-2 flange from D5-3 and preserved Class-A for re-installation at TBD location

• Cheryl, Giacomo, Luke and Paul, FI work inside the PSL enclosure.
• Filiberto, LVEA work, half of the day, HAM3, BSC1 and BSC2 area cableing work.
• Betsy, Jeff B, work in the LVEA, MC3 chamber side work.
• Dave, Jim, CR restart of MC3 model (later on the day), and DAQ restart morning time.
• Apollo working inside the LVEA.
• Hugo, made HAM3 measurements with vacuum purge air on and off.

Starting Matlab TFs of MC3 at 14:12.

We observed peaks around 4Hz on spectra taken last week on HAM3-ISI. LLO folks suggested it may come from the purge air. 

After talking with John and Kyle, we agreed on me turning it all the way down for about an hour. I will now take spectra in this configuration and put the butterfly valve back to the position I found it in (fully open) once I am done.
