Joe and Andres finished adjusting QUAD08 so I started a round of TFs on both chains at 12:52. Order is undamped M0, R0, then damped M0 and R0.
Rolf release RCG tag 2.8.4 today. I have installed it on h1build, and compiled/installed all SWWD IOP models against this. I also compiled h1lsc model but did not install, just to check the compile.
I am testing the new SWWD models and MEDM on the EY SUS and SEI systems at the moment.
All release pointers have been set to RCG-2.8.4, please keep this in mind if you build FE models.
I forgot to mention yesterday that the new cdsutils install includes a couple of new userful features:
New library:
New cdsutils commands:
cdsutils dv H1:SUS-ITMX_M0_OSEMINF_{F1,F2,F3,LF,RT,SD}_INMON
cdsutils audio H1:LSC-DARM_OUT
I removed the rockifo script, which has now been deprecated.

As Hugh mentioned in his alog here we used the HEPI RZ position loop to align the yaw to it's current value. Today we will begin work on ITMx pitch and CPx pitch/yaw.
- SUS needs to do pitch work on ITMX
- Higher dust counts recorded on ITMX (~1000's) than HAM chambers (~10's), this is due to too many volumes open at the same time in the LVEA.
- ISS work on going in HAM2, beam was blocked at MC1 and MC3 for redundant protection.
- Sheila and Kiwamu are preparing for beam splitter install at HAM3
- Jason is going to do a shot and prepare for HWS alignment from the ITMX spool
- Calum and Kate are going to walk about the End stations
- Corey is going to take pictures of the LVEA from the manlift
Particle Counts were taken in BSC3 before and during work activity on the ITM quad. Counts were very high, see below. Work continued because the ITM will be cleaned again before close and because of pressing needs from other groups. Refer to LIGO-T1400024-v4 (https://dcc.ligo.org/LIGO-T1400024) for guidance on particle counts. Would like to see push and draw cross-flow system setup at BSC3. start of work (2 bodies in chamber, no work) 0.3 um 1020 1.0 um 160 5 minutes after above (same 2 bodies, no work) 0.3 um 964 1.0 um 174 5 minutes after above (same 2 bodies, no work) 0.3 um 560 1.0 um 80 5-10 minutes after above (same 2 bodies, no work) 0.3 um 380 1.0 um 50 5 minutes later (same 2 bodies, with some "walking" in chamber) 0.3 um 540 1.0 um 120 5 minutes later (prep for sleeve removal, now 3 bodies) 0.3 um 780 1.0 um 190 5 minutes later (after sleeve removed, now 3 bodies) 0.3 um 1270 1.0 um 210
On Thursday 26th June (following these counts being raised at the morning LHO meeting Bubba et al set up the draw fan on the BSC3 door (opening) as per the attached picture, DSCN0367.jpg. Following the installation of the draw fan I went back to take readings in and around WBSC3. The readings were as follows: - 1) In clean-room outside WBSC3/1 (in middle of room). 0.3 um 50 1.0 um 20 2) In clean-room outside WBSC3/1 (adjacent to draw fan). 0.3 um 10 1.0 um 0 3) In clean-room (in front of draw fan). 0.3 um 150 1.0 um 30 4) In WBSC3 (at opening). 0.3 um 80 1.0 um 10 5) In WBSC3 (just inside chamber). 0.3 um 170 1.0 um 40 6) In WBSC3 (above open flooring, below ITM). 0.3 um 260 1.0 um 70 Clearly the installation of the draw fan has made a marked improvement. However, more measurements are required to confirm this in the longer term. Refer to alog entry https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=12529 for follow up reading taken on the 30th June 2014. ACTION - At next opportunity i.e. when optic can be protected by lens cap the floor (of the chamber) and the flooring should be wiped and vacuumed. Jeff Bartlett has this on his to do list.
On 26th June I also went into WBSC1 to measure the particle counts. No work was going on in WBSC1. The soft door covers were on and the HEPI and outside of chamber were entirely covered with Ameristat sheeting. 1) Outside WBSC1 adjacent to soft door cover, see attached picture DSCN0373.JPG. 0.3 um 50 1.0 um 20 2) Inside WBSC1 adjacent to soft door cover. 0.3 um 0 1.0 um 0
Because the Hartman WFS alignment was going to need the ITMx optics free of FirstContact, we pulled it yesterday. However, we first re-re-removed the QUAD sleeve structure and the 4 vibration absorbers which are in the way of the pitch alignment due to take place today. Also prior to removing the FC, we also found high particle counts in the ITMx chamber. Hugh played around with purge (again) and we closed up the small IAS window at the spool. This seemed to improve things a bit. After taking data on particle counts for a while, we proceeded to pull the FC anyways knowing that we'll have to reclean the optic befor chamber close up.
This afternoon I upgraded the guardian core to r1020, and cdsutils to r250. There are a couple important new guardian features that I wanted to pull in:
I then restarted all nodes with "guardctrl restart --all". All SUS nodes had been shut down for the moment, and all SEI nodes are in watchdog trip states, so this didn't do too much. Some nodes that don't specify initial request states came up with the new NONE request. I set manually reset the requests for those nodes back to what they were before the restart. No major issues:

Find attached the notes from the adjustments to HEPI in response to IAS.
Also see the Auto Optical Level observations showing the level of the ISI Optical Table (<0.007" runout (+-0.0035) on OT) is well within spec.
Before reattaching the Actuators we got the ITMX into position with HEPI. We were ?? X 0.2mm +Y, 0.0 Z, 30urad RZ.
After attaching the Actuators the RZ shifted to -80urads. The DIs are almost useless at this level and a slight bump on the HEPI can shift it at this scale it seems. So I've just used the RZ position loop to hold this. We've got a 70urad target in the ITMX RZ CART BIAS Loop; this holds the IAS yaw to <10urads.
While we were at it, we slapped a few more cart bias numbers in (could use a few more to larger values) to check the IPS cartesian calibration--Looks pretty good but like I said, a few more larger numbers would be informative. There may be some divergence at the extremes of this data. Attached below is a graph of IPS location values and IAS collimating LASER readouts.
IP6 hasn't been pumping since ~06/15/2014 -> Found controller energized but HV off -> Corrected and OK now
We surmise the noisy loops are because we need fresh transfer functions because we shifted the plant: We lowered the HEPI 3+ mm as well as moved a mm laterally. This displaces the SEI Expansion Bellows (Vacuum Seal) and changes the plant resistances. Another reason for the noisy loops, y mainly, may be due to the cleanroom sheets impacting the y motion. Jim also thinks the locked ISI may be altering the plant too much.
I ran Local Range of Motion tests on HEPI and have no problem achieving 0.8mm. The linearity test however looks strange which actually displaces about half as much as the ROM test--see attached. The Verticals look really good but the horizontals suggest some issues. There are no historic linearity plots from ITMX to compare, too bad. My strongest suspision is the cleanroom and I'll stick with that until it can be ruled out before I think about changing HEPI Parker Valves.

This morning we took quick dtt transfer functions on the 6 dofs of ITMx, to check for obvious rubbing : the quad seems to be hanging freely.
dtt templates are saved and commited under the svn :
/ligo/svncommon/SusSVN/sus/trunk/QUAD/H1/ITMX/SAGM0/Data/2014-19-06_1000H1SUSITMX_M0_WhiteNoise_${DOF}.xml
no restarts reported.
As reported yesterday, EQ stops of the intermediate mass for all MC suspensions looked really close. Attached shows two EQ stops for MC3, and one of them was very close though it was not touching. Other mirrors looked similar to me. These are all with MC mirrors already aligned, while the EQ stops are typically set without suspension biases.
I asked Betsy and Travis to have a look. They went in, said that MC1 was OK but they backed off some screws for MC2 and 3.
First set of measurement failed. Started them again at 23:52:23 UTC.
Transfer functions ran yesterday in the staging building are showing clear sources of rubbing especially in the pitch/length/yaw degrees of freedom for the reaction chain. Main chain has large unexpected cross couplings in pitch.
Andres and Jeff realized the cover was on during that measurement, which is why results were bad. We started them again Friday overnight.
