I did a major cleanup of the Tip-Tilt screens and linked them to the LHO SITEMAP.

I created argument macro files $(USERAPPS)/asc/common/medm/asc???_overview_macro.txt with all the optic-specific arguments (analogous to $(USERAPPS)/sus/common/medm/sus???_overview_macro.txt for SUS). I then went through all the screens in $(USERAPPS)/asc/common/medm/asctt with gedit, changing link arguments to look like the following:

args="%(read $(USERAPPS)/asc/common/medm/asc$(optic)$(num)_overview_macro.txt),USERAPPS=$(USERAPPS),SITE=$(SITE),site=$(site),IFO=$(IFO),ifo=$(ifo)"

Formerly some of the screens expected $(OPTIC) to be the full optic name, and some used $(OPTIC)$(num), so I changed everything to the latter convention.

Details of which files were touched are at end. I want to do one more round of checking for errors, so I haven't yet committed the changes yet.

No change:

ASC_CUST_TIPTILT_DAC_MONITOR.adl, ASC_CUST_TITPTILT_SAFE_SNAP_CMD.adl

Basic updates:

ASC_CUST_TIPTILT_BIO.adl, ASC_CUST_TIPTILT_DC_ALIGN.adl, ASC_CUST_TIPTILT_M1_COILOUTF.adl, ASC_CUST_TIPTILT_M1_DAMP.adl, ASC_CUST_TIPTILT_M1_DRIVEALIGN.adl, ASC_CUST_TIPTILT_M1_EUL2OSEM.adl, ASC_CUST_TIPTILT_M1_LOCK.adl, ASC_CUST_TIPTILT_M1_OPTICALIGN.adl, ASC_CUST_TIPTILT_M1_OSEM2EUL.adl, ASC_CUST_TIPTILT_M1_OSEM_ALIGN.adl, ASC_CUST_TIPTILT_M1_OSEM_ALIGN_counts.adl, ASC_CUST_TIPTILT_M1_OSEM_ALIGN_??ZOOM.adl, ASC_CUST_TIPTILT_M1_OSEMINF.adl, ASC_CUST_TIPTILT_M1_SENSALIGN.adl, ASC_CUST_TIPTILT_M1_WD.adl, ASC_CUST_TIPTILT_M1_WD_ACT_BANDLIM.adl, ASC_CUST_TIPTILT_M1_WD_OSEMAC_BANDLIM.adl, ASC_CUST_TIPTILT_M1_WD_OSEMDC_BANDLIM.adl, ASC_CUST_TIPTILT_MONITOR_OVERVIEW.adl, ASC_CUST_TIPTILT_OPLEVINF.adl, ASC_CUST_TIPTILT_OPLEVINF1.adl, ASC_CUST_TIPTILT_OSC.adl, ASC-TIPTILT_Main.adl, newDisplay.adl

More complicated fixes:

ASC_CUST_TIPTILT_DACKILL.adl: fixed broken link to GDS_TP screen.

Broken - needs redesign:

ASC_CUST_TIPTILT_M1_DEMOD.adl, ASC_CUST_TIPTILT_M1_TEST.adl: need to fix links to $(USERAPPS)/cds/common/medm/FILTALH.adl (2 places)

ASC_CUST_TIPTILT_BIO_all.adl, ASC_CUST_TIPTILT_MONITOR_OVERVIEW_all.adl, ASC_CUST_TIPTILT_OVERVIEW_all.adl: only allows for four (not five) TTs.

Lots of unfilled schedule promises on my part this week but finally yes, the ISI is now in the chamber.  No real issues to report on this just the usual it takes a while to set things up and turn a lot of bolts.  Actually the roll into the chamber was one of the easiest with the fixture well positioned and centered.

Job well done on the Prep with DevilEd, Scott, Randy, Greg & Mitchell, directed by Jim.

This volume had been vented until pumped this afternoon -> No change on the helium signal but there was a small response in total pressure indicating small inner O-ring leak on septum -> will leave under vacuum

As part of our hunt for helium sources - today I pumped the HAM1/HAM2 annulus volume briefly with a scroll pump but stopped as the system wasn't sealed enough -> The East door of HAM1 is currently hung on (4) door bolts and is likely not in full contact with its O-rings -> I UltraTaped the outside of HAM1's East door flange and again pumped the annulus volume but stopped as I deduced that a leak via the inner O-ring was apparent -> As such, the interior of HAM1 may have experienced some "wind"

SLC Team and Apollo

Cleanroom footprint was expanded to the wall (pic 1). 
Weldments, Face Plates and Cylinder were moved into the LVEA (pic 2).
Assembly/Installation Fixture and Balancing Fixture were moved into position (pic 3).
It was identified that the Gate Valve Annulus Piping needs to be removed for installation of baffle (pic 4). This was discussed with John Worden and approved.
Team will begin assembly in the AM after cleanroom has been wiped down and particle count is acceptable.

The large tooling has been at LHO for about two years. The Pusher Brackets which are needed for balancing have not been located. The team will request parts be sent overnite from LLO.

We

 - debugged the shutter software, and got it to work
 - switched the shutter control cables between shutter control 2 and 3
 - set up the appropriate threshold for the shutter (0V)
 - placed an iris in the main beam path to guarantee that the shutter protects the RFPD
 - verified the safety of the RFPD by moving PRM, and measuring the max power out of the RFPD.
 - aligned the RFPD to the weak ITMY reflected beam (with the PRM misaligned)
 - switched the supply cables between POPAIR_A and REFLAIR_A (they are now going to the right input)
 - verified that we see fringes on the DC readback
 - turned on the REFLAIR_A_RF9_LF power supply, verified that all whitening is 0
 - verified that we get a signal in H1:LSC-REFLAIR_A_LF_OUT
 - moved the RF cable to the REFLAIR demodulation board (i.e. the signal currently does not go to the real common mode board)
 - verified that we have a signal in H1:LSC-REFLAIR_A_RF9_I_OUT
 - verified that its whitening is all off
 - tried to lock the arm cavity, but had excessive pitch motion

PS:
 - The RefCav is still pretty lame in re-locking

The primary parabolic mirror of H1 TMSX turned out to be about 80 to 100 thousandth of an inch thinner than in the DCC drawing (https://dcc.ligo.org/LIGO-D1000075).

The thickness at the thinnest and the thickest edge were measured to be [1.608", 2.868"] VS [1.69, 2.97] in the DCC drawing.

The specification (https://dcc.ligo.org/LIGO-E0900347) states that it should be 43+-1mm or 1.693+-0.039" at the thinnest edge.

OTOH, the manufacturer certificate of compliance (https://dcc.ligo.org/LIGO-E1300278) states that the spec is 41+-1mm or 1.614+-0.039", presumably at the thinnest edge, that's about 80 thousands right there. Either the mfg or the spec document is wrong.

Either way, the consequence is that the mirror thickness as of now is outside of the adjustment range of clamps, and the clamps don't touch the optic at all. 

Bottom two clamps: You can easily insert a 25 thou metal between the mirror and the bottom clamps (picture), but I couldn't slip 50 thou washer.

Top clamp: I didn't want to risk dropping a metal piece on the center of the optic, so I didn't slip anything to the top. However, the top thickness is 1.608", and the clamp is designed to accomodate 1.68" or thicker optic, so it seems as if there is a 70 thou-ish gap.

After a conversation with Ken Mailand, I decided to re-machine the clamp locally to shave off 100 thousandth from the top of the clamp standoff. Hopefully Tylor can do it by the end of Thursday and Justin can slip them in the next oven load.

Here is the current status of the aLIGO SEI work regarding the HAM chambers. Everything in bold is to be completed for HIFO-Y. Everything in red is a change from last week's status. Everything in green is available.

The SUS offload signal path that was left enabled on HAM3-ISI. MC2 motion was sent to he input of the ISOlation loops (see attachment), making them unstable. I turned the related filter banks OFF.

Both HAM2 and HAM3 ISIs are isolated, and stable. Filters used are the same as during the IMC test.

First, (additional), the three Septum Window Blanks were removed, wrapped, bagged & labeled (D1102278-v1, SNs 9, 10, 11.) There was one hole on the Septum that ScottL found hard to remove; this was the 4oclock hole on the south of the three windows.  The bolt was compromised with evidence of damage/dragging.  I have the bolt out of circulation in hand if you are interested.

We completed the second half of the Stiffening Bracket attachments (D070302)(See photo1) to the Lower Riser (D070301.)  Pain, lots of thread cleaning, rinsing, threading, cleaning, rinsing etc.  We did not gall any but this is what took us the long time--making sure we did not gall.  The final Risers (D1200353) were installed and torqued with Tooling Bar confirming position--photo2.  It's all good & ready.

Thanks much to Tyler & Scott for making it happen.

Dan upgraded the QLogic switch in the LDAS server room yesterday. h1fw0 went unstable around that time, restarting on average several times an hour. This afternoon Dan upgraded the QLogic switch in the MSR. He also at the same time upgraded the switch in the H2 EE building on the DTS. We will monitor h1fw0 to see if today's upgrade fixed the problem.

Suspecting that the unusually high dust counts > .3 microns reported by this dust monitor might be a hardware issue, this morning I put a zero count filter on it. No counts should be registered with the filter on. Counts are still being registered however, but less of them.

Fairly quiet day, lots of traffic to end stations staging parts and equipment for baffle install, photon calibrator work and TMS.

-Hugh working around HAM6

-0900 Visitor from Mission Support Alliance doing vegetation survey at EY. Work complete by 1600.

-1030 Arnaud running TF's on ETMY

-1200 Hugo running TF's at HAM3

-1530 CDS and LDAS updating firmware in MSR to correct error on fw0

This was done yesterday in preparation for moving it to HAM 6. It was in the clean room over HAM 3. It was moved out of the clean room, but has not yet been moved to HAM 6. It is still off.

The default NDS server has been changed to h1nds1 for all new processes effective 10:34 PDT.  

SLC Team: Lisa C. Austin, Scott Shankle, Mike Vargas, and Nichole Washington - visiting LHO for assembly and installation.

The team went to X-End with Jodi F. to see and get a feel for the amount of working space and to map out the logistics for the assembly. The large parts will have to be craned to the assembly area (see pic 2). Jodi and Apollo are doing their best to 'expand' the cleanroom footprint for assembly and balancing. The orange conduit crossing the installation area needs to be moved (see pic 3).

Apollo transported the weldments, cylinder and face plates to X-End (see pic 1).

Gerardo M. assembled the Assembly and Lift fixtures.

ISCT1 REFL BEAM Polarization Measurement: We used a cube to measure the polarization of the ISCT1 REFL beam out of the periscope. We found the polarization to be s-pol. 

Optics Added: With the PSL at 1Watt, the power of the ISCT1 REFL beam at the periscope is 0.68W. However, the PD on the table used as a trigger for the shutter saturates at 6mW. Thus, we placed a W1 45S beam splitter with the AR coating in front of the shutter to reflect 2mW of light onto the PD. We also placed an iris in front of the PD to single out the beam. And finally, we placed a lens in front of the PD to reduce the beam size.

Note: One of the shutter controller boxes has been modified (see LIGO-E1300580-v1); however, the top one remains to be changed. 

Tuesday CDS Maintenance Summary

EX front ends (DB,MB,VL,HP):

we started the first version of the following models at EX: h1susetmx, h1sustmsx,h1susauxex,h1susitmx. These were added to the DAQ and the DAQ was restarted.

ITMX SUS and SUSAUXH56  (MB,DB):

The h1susitmx and h1susauxh56 models were started for the first time. They was added to the DAQ and the DAQ was restarted.

Beckhoff EDCU channels (DS,DB):

The latest Beckhoff INI files for the DAQ EDCU were added to the DAQ and the DAQ was restarted.

LDAS QFS maintenance (DM):

Dan performed maintenance on the LDAS QFS system in the LSB, this causes some restarts of h1fw0.

Front End Filter coefiicient loading (JB,DB):

All front ends with partial filter module loads were reloaded to ensure all modules were updated. A problem with the h1susbstst filter file was fixed by Jim and restarted.

Hourly autoburt backup (DB,JB):

This system stopped working after the epics upgrade to U12.04. It was reset back to the earlier version of EPICS and is now working again. Some out-of-date autoBurt.req files are causing problems with this system and are being worked.

New ASC LSC models (MB.DB):

First versions of the h1asctt and h1omc models were built and installed. They were added to the DAQ and the DAQ was restarted.

MSR temperature EDCU (DB):

The Beckhoff readout of the MSR temperature was added to the EDCU and the DAQ was, you guessed it, restarted.

CDS OVERVIEW MEDM (DB):

Modified to show all the new models which have been added today.
