EY WFS autocentering

(Sheila, Daniel)

We installed 2 MCL PZT drivers, 2 PZT steering mirrors, a DE-to-SE driver chassis, and associated cabling in EY. The ISCEY model updates were already introduced during the last maintenance perdiod. The electronics and software are turned on and ready. The DAC outputs to the MCL drivers have been tested. The mirrors still need alignment once ETMY is back under damping and aligned. A simple integrator has been loaded into the new filter modules. Documentation can be found here.

Restarted models and framewriter for the Seismic test stand
Staging building seismic test stand - Restarted both models and the framewriter and nds processes to get the time sync'ed properly.  Tested using diaggui to do a transfer function, test passed.

ETMX ISI is locked
Went down to EX after lunch and locked the ISI, after Hugh turned off HEPI offsets. I had to move one of the witness plates on the floor, because I had to slide under the suspensions to get to the far side of the chamber. To reach the lockers, I had to steal a clean-er stool from the LVEA from around HAM5, as our regular in-chamber stools have been mis-placed, wiped it down multiple times, and foiled the base. Wherever this stool came from, we should get a couple more because it was the perfect height for this job. Slid nicely under all of the suspended obstructions, but tall enough that I could reach the lockers. I left the stool down there sitting outside the chamber in-case TMS needs it.

SR3 "rubbing" alleviated

Although I did not really find a smoking gun on SR3, I moved a few EQ stops back and recentered one middle stage OSEM (LR).  Now, V and P TFs seem healthy.  Moving on.

purge in LVEA

Kyle came out and checked the purge in the LVEA in light of the fact that we removed the dam - he reports that it is "normal" and functioning as best as it can.  Note, he also reported that he checks it every other day.  Good.  

 

To all:  Please alog if you are adjusting any purge - I'm trying to catch a phantom.

SR3 fails TFs

In the midst of beam hunting this morning, we started quick TFs on SR3.  We immediately see some rubbing as V TFs don't look healthy.  I took a quick glance at the SUS and did not see anything obvious.  Aargh.  Back at it after a quick lunch.

SR alignment, continued

In an attempt to resume alignment of the output HAM optics, this time with the aligned ITMy, we unshuttered the PSL beam and entered HAM5 to look for it.  We found nothing.  Tracing steps backwards, we seem to find that the bypass optics near MC3 got brushed yesterday during the ground look hunt.  The PSL beam hits the monument on the wall a bit off in yaw.  So, we'll need to reflash the MC and tweek up the alignment of the bypass.  Kiwamu has already adjusted the power leaving the PSL down to 200mW.  After lunch, we'll start again.

SR3 lower stage OSEMs aligned

Jeff and Andres spent the morning aligning the SR3 2 lower stage OSEMs.

Andres R. & Jeff B.
   After completing the magnet repair on SR3, we recentered and realigned the AOSEMs on the Intermediate and Test Masses. The AOSEMs have been adjusted to 50% light. No problems were encountered during alignment or centering.
 
   Left SR3 suspended with the EQ stops set close to their final positions.   

Particle Counts: 
Before Work
In cleanroom, Cover on: 0.3 = 10, 0.5 = 8, 1.0 = 2
In chamber, Cover on: 0.3 = 346, 0.5 = 202, 1.0 = 46
In chamber, Cover 1/2 off after 2 Minutes: 0.3 = 107, 0.5 = 59, 1.0 = 12   

During Work
In chamber, Cove 1/2 off: 0.3 = 30, 0.5 = 17. 1.0 = 9  

After Work
In cleanroom, Cover on: 0.3 = 0, 0.5 = 0, 1.0 = 0
In chamber, Cover on: 0.3 = 8, 0.5 = 4, 1.0 = 0

EndX Uncontrolled HEPI Position during vent
The opportune shut down of the HEPI Pump during the vent allowed the HEPI Mechanical to respond to the change of state.  The Z & Y dofs trend 10s of um with the Y sliding 60um.  X waffled around in a window of 3um so basically didn't move.  The yaw and tilts are a couple to 15urads so again maybe nothing.  See the attached trends remembering the local sensors these are derived from are from the top of the SEI Piers to the suspended HEPI.  So, there is most likely coherent motions relative to the floor that these don't see.

Vacuum EPICS Gateway Traffic
Last Thursday, I modified the allowed PV list to further exclude FMCS channels which do not exist in the vacuum subnet (/H0:FMC-.*_H2O_PRESS.*/ rather than /H0:FMC-.*/).  Attached is a plot of the corresponding reduction in broadcast traffic in the vacuum subnet.  The second plot shows this change (in 'Week 28') relative to the previous change (in 'Week 27') that eliminated most of the redundant broadcasts for reference.

ETMX SEI HEPI Also stopped Sunday with Overvoltage

At essentially the exact same time as the EndY shutdown reported yesterday, EndX HEPI Pump Station stopped its output with a OV3 error. Suppose this makes sense. The LVEA road through this fine. Pump Station restarted in the documented manner.

EX Newer Dust Monitors and New Code

NOTE to Operators (and others)

With the EX Chamber work, there have been a pair of new Dust Monitors installed (along with new code, alog12738).  Unfortunately, the Dust Monitor signals aren't connected to alarms, and do not come up on the main EX Dust Monitor Screens.  You can find out counts on these Dust Monitors by bringing up their Expert Screens.  So, we will want to look at these screens every  now and then. 

The Dust Monitors work locally, so those doing in-chamber work should be mindful of any audible alarms (if any) the Dust Monitors may give.

BSC1-BSC2 dam removed

Since IAS finished taking this morning's alignment measurements, Travis and I went into BSC1 and dropped the dam that was standing between BSC1 and BSC2.  It is currently laying under the ITMy QUAD in the chamber in the event we need it again soon.

WBSC1 ITMy Alignment
IAS: D. Cook, J. Oberling
SUS: B. Weaver, T. Sadecki
 
After yesterday's alignment work, we did one final check on the ITMy this morning before the hand off for the output arm work.  The ITMy alignment errors are currently:

It should be noted that the pitch is without the 352 µrad correction for the First Contact currently on the HR face of the ITMy; this will have to be corrected for after the output arm work, in addition to the yaw and the X axis position.  Also, I applied a +40 yaw bias to the ITMy.  This zeros the yaw in our alignment equipment (the current slider calibration is a little off).
