This an alog from last week install :

After TMSX has been installed under the ISI, I took a set of undamped transfer functions using the same dtt template as the first set from alog 7514 (when TMSX was on its testbed).
The attached results are showing :

(1) H1 SUS TMSX transfer functions against the "tmtsopt_firstarticle" model for the 6 degrees of freedom

(2) H1 SUS TMSX (2013 Sept 11 under ISI locked, in pink), against H1 SUS TMSX (2013 August 21st, testbed in black) against first measurements of L1 TMSX (2013 Sept 13, in orange) against the model.

The TFs from LHO have been measured using a swept sine excitation from 0.1Hz to 10Hz with a low resolution (30 to 40 points). The coherence for most of the points was above 0.8, for each degree of freedom (the coherence saved in the dtt templates).

They show a good agreement with the peaks from the model, except for the last mode of Roll that is shifted down. It seems like a similarity with tmsx from livingston.

We were able to get the suspension and the box assembly attached to the test stand, the next step is to adjust the length of the baffle and balance.  After that we'll be wrapping up the suspension, the box, and large tooling to be sent down to the end station.

After several days of testing, we finally found the issue on the BSC-ISI in the staging building. Turns out 2 out of 3 pigtail cables haven't been engraved properly. As a result, the all GS13s cabling path was messed up.

After testing all the cables one by one and plugged everything properly, it became pretty obvious that we have 2 bad GS13s on this unit (H3 and V1).

Next step:

- we need to find a way to change the engraving of the cables

- we'll change those 2 GS13s in the next days

- we need to check the engraving of the L4Cs cables.

Seeking to reproduce conditions of RGA scan taken earlier this week 

Days Notes

• HAM5 Cleanroom in place & sealed up (Apollo)
• HAM6 HEPI Commissioning this morning (Hugh)
• Rebuilt/restart all SUS Quad models (Barton)
• BSC-ISI work at EX...possibly balancing today?  (Warner)
• Satellite Amp box swapped for ITMy (Filiberto for Kissel noise hunt)---this tripped SUS/SEI watchdogs!  Which I didn't put together until Mark figured it out.  
• Arm Cavity Baffle Work continues (Gerardo, Thomas, Tyler)
• network cable down Xarm & HAM6 work in LVEA possibly?
• Sheila/Alexa continue ISC Table work in east bay
• Pulling fibers/clean up at EY (Filiberto, Cyrus)
• Flooring Trim work was supposed to happen today, but haven't seen anyone at EY.
• Dust Monitor swapped at EX (Patrick, Richard)

Visitors

• Hanford Fire crew on site working on Pumps
• contractors:  Overhead door, Paradise water, porta-potties, Praxair at MX, Roofers at EX

The new roof membrane is being glued in place at ENDX. A second crew was brought in today (due to rain at another job site) and has started at the Mid station stripping the flashing.

After getting the code back up and running I replaced the dust monitor that quit communicating with the corner station with  one provided by Patrick.  The New one is working just fine.

This took far longer than planned.  I was working on it yesterday only to find out that the code had been stopped so all the work yesterday was repeated this morning.  Then realized no one had tried the basic swap of monitors so this was the logical step for testing.  Once replaced I booted the comtroler again and Patrick restarted the code.  Everything appears to be working now.

Satellite S1100057 was replaced with S1100178 (MO_Left, MO_Right, RO_Left, RO_Right). This was done to help Jeff Kissel search for a 5.1HZ excitation signal he reported:

The optical timing distribution system in the staging building is no longer in sync with the master timing in the MSR.  Because of this, the GPS time of the models running on the test stands is off by a second or two.  This should be fixed at some point when it is convenient to shut down the models and troubleshoot the system.  Until then, the system should work so this repair is not urgent.

This affects both seismic and suspension test stands in the staging building.

Find attached some performance plots for BSC-ISI BS. Those first results are promising, even if there is room for improvement and tweaking.

This configuration was on all night (very stable). Spectra presented were measured at 1062915770 (start time) during 45 minutes.

I fixed the problem from LLO alog 8659, ECR E1300715, Bugzilla 398 and LHO WP 4124 where due to an error in the L1 and L2 blocks of the QUAD_MASTER part, the outputs of the DAMP block were plumbed incorrectly.

I svn upped Stuart's corrected QUAD_MASTER.adl and checked that it was being picked up by h1susitmx, h1susitmy, h1susetmx, h1susetmy and h1susquadtst.

I did a make and make install- on all five models.

I restarted all but h1susetmy (which is offline during the chamber move).

I BURT restored all but h1susetmy to 10:00 and reset watchdogs on h1susquadtst and h1susitmy (h1susetmy is offline, h1susitmx isn't connected yet, and h1susetmx had been tripped, presumably due to SEI activity).

Attached are plots of dust counts requested from 4 PM September 15 to 4 PM September 16.

New tests have been done on the BSC-ISI in the staging building (to see the first results, go to log #7718):

1. We swapped the feedthrough between corner 2 and corner 3. Doesn't change anything: the feedthrough in corner 3 seems to be good.

2. We use 2 cleaned breakboards and an oscilloscope  to track the signal of the GS13 in corner 3. The first one was directly plugged into the sensor, the second one at the end of the pigtail cable. The signal coming out of the first one seems to be good: nice amplitude, reacts at low and high frequencies. The signal coming out of the second one looks bad: very weak amplitude (factor of 200 compare to the first one), no reaction to DC excitation.

We swapped the pigtail cable with the one from corner 2, and even with a new cable: no changes.

3. We used this new cable and a new GS13 in corner 3: no changes...

Thus no conclusion yet, we're still investigating.

Still not in pressure equilibrium-intended scan requires 

Run time used for 44" electric gate valves not applicable for 48" gate valves

Will take an RGA scan later this afternoon then open GV2

I stopped the IOC for the dust monitors in the optics labs to test them with revised code. I did this twice. The first time I tested the new code as controls on h0epics2 running Ubuntu 10.04.4 LTS. This unsurprisingly did not work, because it was compiled on sysadmin0 running Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-41-generic x86_64). The second time I ran it as patrick.thomas on opsws8 running Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-51-generic x86_64), which did work.

This was done from approximately 15:50 to 16:35. The old IOC is running again and was burtrestored to 08:00 today. However, there was a problem with the EDCU, which did not seem reconnect to the channels after the old IOC was brought back. Dave restarted the DAQ and it seems to be working now as of around 17:20.

I have attached plots of the relevant channels over the time in question. When the mode is changing the data should be good. The data appears to have been lost for these dust monitors from around 3:56 PM to 5:10 PM.

ETMx Silica-tipped Earthquake Stops Positioned on Quad (Andres, Corey)

The face EQ stops for the ETMx needed to be positioned, but we don't want "glass on glass" contact.  We didn't have thin teflon strips to insert between the EQ stops and the glass, so per Betsy's suggestion, we used Alpha Wipes as a buffer between the Stops & Glass.

SUS TMS Cable Fixed

Installed screws on an in-vac cable which had these screws missing from its connector.  All TMS cables are good to go for dressing on the ISI.
