Quality/Safety (Nolting)
LIGO Lab Safety
- The LIGO Safety team has been preparing for the LSO Laser
Safety Workshop scheduled for next week at Caltech. The
supporting document, LIGO-M0900241-V2 Laser Safety Training for
Certification and Recertification of LIGO Personnel has been approved
and is now available in the DCC. This in-house workshop is the
beginning of a planned annual event for all LSO’s to come together as a
team; sharing issues and concerns. Also, to learn new techniques
and rule changes as well as Lessons Learned” throughout the year,
between workshops.
- The LIGO Laser SOP Template has been
copied from the LIGO Laser Safety Plan, and is now a stand-alone
document (M0900287-v2) and is available in the DCC for review.
Please use this template to assist in completing any SOP’s that may
have been required due to equipment changes, operating procedures, or
any additional circumstances that warrant updated instructions and
safety measures.
LIGO
Hanford
Observatory (LHO) and Interferometer Operations (Raab)
Summary of Activities at LIGO Hanford Observatory (compiled by M. Landry)
- After landing ISCT4 due to fears the floating table and/or misbehaving controller were inducing glitches, we noted excess noise
near line harmonics. Broad peaks were seen between 120 and 130 Hz and
between 180 and 200 Hz. Checking alignments on the table and refloating
appears to have largely mitigated the structures, but we're presently
unsure why. The controller for the air bearing may be swapped out.
Ranges continue to be down a few Mpc from their high-water mark
post-vent (say 15Mpc at 14W, down from 18Mpc), so that we will continue
to investigate ISCT4, and, owing to detchar feedback regarding
accelerometer glitches on ISCT1 and WFS3/4, alignment on the REFL port.
Microseism noise has been high and we see some anticorrelated trends in
the range, so that an upconversion study is to be made. The duty cycle
for the week was thus 56%, ranges from 12-16Mpc.
Squeezer Update (D. Sigg, S. Dwyer)
- Continuing with the procurement of electronics components.
We are working on RF amplifiers, TTFSS units and common mode boards all
at the same time. We received the PD interface boards and assembled the
first chassis. It has been shipped to MIT. Richard and Filiberto also
shipped 4 power supplies which will be used to generate the 24V and 17V
rails. We received shipment of the auxiliary laser, the PZT HV driver,
cameras, monitors and some additional optics mounting hardware.
LIGO
Livingston Observatory (LLO) and Interferometer
Operations (Giaime)
General Operations (Rusyl Wooley)
- In addition to running the instrument, processing aLIGO
parts and working on aLIGO FMP projects, we focused on getting the
vacuum prep and optics lab clean so that they can be occupied
again. This is the conclusion of the work required to replace the
floor in the two labs.
Enhanced LIGO Commissioning & S6 Run (Valera Frolov)
- The communication problem between the OMC and the LSC front
end codes has been addressed by implementing the code that enforces the
proper exchange of the data between the OMC and LSC computers over the
reflected memory. The error checking was also put into the code so that
the data can be flagged when there is a timing error.
- The
interferometer locking was sporadic this week due to the very high
microseism - well above 95% level. On Wednesday the ground motion
subsided for several hours and the 16 Mpc range was recovered during
that time. Unfortunately the useim quickly rose in the afternoon to 5-6
um/s.
- The L1 calibration run is underway this week. The
strength of the large optic coil actuators is being measured using
various methods including the radiation pressure calibrator (Pcal). The
goal is to understand and possibly eliminate the 10-20% uncertainty in
the magnitude of the L1 calibration transfer function which is coming
from using various techniques but mainly from symmetric vs asymmetric
Michelson measurements.
LLO CDS (Keith Thorne)
CDS - Hardware:
- AdvLIGO Sus Test Stand - Carl finished up work on this. Setup and initial alignment of most OSEMs is complete, but PUM OSEMS need alignment.
- TCS - Carl worked on document verification.
- DAQ Test Stand
- Carl wired up DC power supplies and installed DTS server. Still
need to run fibers to connect 1PPS to eLIGO master. Keith
configured the firewall router and DTS server. He still needs to
set up the front-end on the internal LAN.
CDS - Software:
Operations
- Atomic Clock UPS - Keith and Mike Fyffe installed new
batteries in UPS for atomic clock. Found one battery had never been
connected. One battery pack had to be decommissioned due to
leaking batteries. Disposal was handled using approved procedures.
- Main Network Switch
- Received replacement power supply and a spare. Will install
next maintenance period. Still need replacement fan module.
- Framebuilder
- Alex updated the framewriter software to correct the reported sample
rate in the trend frame metadata. Keith got the backup GDS
broadcaster working by resetting the Infiniband connections on FB0.
Upgrades
- Fileserver Upgrade - Keith successfully booted
existing VME front-end from new server. Now migrating all
scheduled tasks, etc. from old to new server. Still deciding best
method to do switchover.
- OMC->LSC RFM communications
- Matt Evans and Tobin Fricke added robustness and error detection to
the reflective memory communication between the OMC and LSC front-end
software. This is more difficult than in the past because the OMC
DAQ sample rate is twice as fast as the LSC. This change allowed
use of the version 1.1.1 RCG for the OMC code at LLO and has reduced
the digital noise to the needed level. A presentation is planned
for next week's CDS meeting. Code changes have been uploaded to
the CDS cvs system.
- CDS LANs - Keith tested EPICS
gateway configurations between LANs. The goal is to allow the
FrontEnd and ControlRoom LANs to exchange EPICS variables in both
directions over the gateways.
LLO SEC (William Katzman)
- Conducted Docent training on light-related exhibits for SUBR SEC docents.
- Continued scheduling groups.
- Conducted five field trips for over 200 students.
- Met with Jon Elvert from LASM regarding providing a joint professional development program for teachers.

Advanced LIGO
Systems
From: calum torrie <ctorrie@gmail.com>
- Systems Drawings - Ed and I with input from Dennis
have been adding the laser to the systems drawings. The laser is now in
both H1 and H2 SolidWorks assemblies available on the PDMWorks vault
and the beam can be seen down to the chamber level. Ed is currently
updating all of the e-drawings and jpg's on the DCC to include the
laser. An example can bee seen at the following link: -
https://dcc.ligo.org/cgi-bin/private/DocDB/ShowDocument?docid=1410.
Also in the above link on page 3 of 5 you can see our first attempt to
gather useful information for initial alignment of the suspensions on
the table. Further work is needed here and we are in discussion with
AOS, SUS and both sites on this.
- CG of HAM Seismic Table
- Ed and I are working with Andy Stein to look at the CG of the HAM
table plus payload. The ides is to see if any of the mass allocation
can be transferred from seismic to payload. We will also gather CG

Modeling and Simulation
From: Hiroaki Yamamoto hiro@ligo.caltech.edu
Static IFO Simulation (Hiro, Sany)
- 40m IFO : Calculated the mode mismatch effect if SRM is used
for PRM. The mode mismatch is small, but the power drops down by 15%.
This situation, not huge mode mismatch causes large power drop, is the
situation observed when the astigmatic effect is studied for advVirgo
stable cavity design. The cause of this effect is under investigation.
- 40m
IFO : the thermal effect of ITM was studied. The arm cavity mode change
and the mode coupling of the arm and recycling cavity are both
negligibly small.
- Large loss due to absorption imbalance :
The validation of this effect using melody is still under way.
Supplementary result to trace the difference of FFT and modal model was
sent to Ray Beausoleil.
- Input beam specification : SIS accepts input field by loading data files.
- Enhancement of SIS to speed up the locking process and the stationary state search.
- Sany
Yoshida sent me an algorithm to speed up the simulation of the stable
cavity focusing mirror. It is being analyzed if it fulfills necessary
feature to simulate the mirror edge effect.
Time Domain Simulation (Hiro)
- Worked with a LCGT student to design a guided lock modeling.
Safety
From: David Nolting dnolting@ligo-la.caltech.edu
- Efforts continue to develop standard operating procedures for the new clean and bake equipment for both LLO and LHO.
- Research
into the new R&D Electrical Standard is being done at this time to
ascertain how it applies to the equipment that is designed and
installed at the observatories. Much of the concern is with
equipment that is not certified by a 3rd party such as the Underwriters
Laboratories (UL). A briefing will be made once the rules are
interpreted and understood regarding LIGO systems.
Quality Assurance
From: Mick Flanigan flanigan_m@ligo-wa.caltech.edu
QA:
- Spent time with Armando getting him ready to take
measurements on the HEPI actuators here at LHO, as I will be traveling
the next several week. Armando will be providing the reports to me for
upload to the DCC. Thanks to Hugh for getting us the medium granite
table.
- Core Optics Wiki is up, am working on designing the
tool. Risk Registry template has been designed, and will be loaded this
week.
- Reviewed update#2 of the LIGO QA Plan, the document is under revision to modernize for Advanced LIGO.
SEI:
- Schedule for dimensional testing is on track for the large blades. Scheduled for 11/03/09.
AdLIGO Risk Registry:
- Rewrote and submitted request to PNNL at Hanford for a more
accurate quote for a gamma survey at the vertex BSC chamber area, to
quantify the potential presence/influence of ionizing radiation on the
area, particularly the buildup of static on the optics. SOW can be
found at DCC# C0900951.
Inventory Control System:
- Spent a large majority of time this week tracking bugs in
the system, testing fixes. We have been chasing a series of bugs
through the bulk parts module in the database, and every time we think
we have a problem beaten, we move down the path another step or two to
find another issue. It is going to take some further work to wring
these out of the system to avoid future corruption of parts records,
get the system stable enough to run long term. The latest critical bug
has been reported fixed tonight, and we will test tomorrow.
- Will
be giving training to the CIT team in early Nov on the ICS system,
entering data, parts, tracking etc. Will also be working Zsusa Marka at
Columbia next week to get several electronics components prepped for
entry, shipment to sites.
Facilities Modifications and Preparations
From: John Worden <worden_j@ligo-wa.caltech.edu>
- LHO - Continued progress in assembly/clean/bake areas. See elog here
- LLO
- The Galli-Morelli oven has been baked out (empty) and FTIR samples
taken. These samples will be shipped to JPL for a baseline analysis.
Seismic Isolation
From: Ken Mason kmason@ligo.mit.edu
SEI electronics design and fab:
- The 8-Channel Valve Drivers are being tested. Things are
progressing well. I'm starting to make a block diagram for the BSC ISI
electronics that is required for the FDR.
- I have gotten a
quote for the longer L4C cables. We are able to save $10 each by
re-using the circuit boards on the old cables. When those come here,
we'll take the old cables off, and ship them to Ticor.
- The
internal Pier Interface cable that goes to the Inductive Position
Sensor boxes needs a connector put on one end. Hugh is sending us these
cables, and we'll put the connectors on.
- Mohana is making the front and back panels for her Coil Drivers.
- Emery
is finishing up his cable list spreadsheet. He and I are going to meet
later today so we can review the HAM ISI in-vac cables list, and make
sure we have everything. He will assign flanges, and compile a master
list soon. ~Ben
Single Stage HAM Procurement and Build HAM SEI design:
- Created Excel spreadsheet (LIGO-E0900329) for calculating total mass and center of mass for the HAM ISIs with payload. ~Andy
- The
HAM bellows contract has been placed. Paperwork for the procurement of
all BSC ISI instruments is now either underway with the procurement
department or has already been completed (Trilliums, GS-13's, L4C's,
large and small actuators, position sensors). ~Stephan
- Quotes have been received and are being evaluated for the HAM shipping containers and trim masses.
Two Stage BSC Design and Procurement:
- Stage 2 redesign: Michael Hillard has completed draft
versions of mechanical drawings for almost all machined parts in Stage
2.
- We prepare the Final Design Review. We are finishing and checking the design. We prepare the documentation and the drawings. ~Fabrice
Suspensions
From: <justin.greenhalgh@stfc.ac.uk>
ALUK held its latest Project Management Committee on 14 October 2009 (See LIGO-M0900285-v1). A brief activity summary follows:
OJEU process status as follows:
- Machined items. We are about to order the bulk of the residual machined items.
- Weldments.
We remain in discussion with the vendor and the US team about the best
way forward vis-à-vis the cleaning and RGA testing; at least one
workable solution has been proposed.
- Blade springs. No change since last month: ETM/ITM blades shipped. BS/FM blades characterised and ready to ship.
- The
final training session was delivered at LLO last week . Work also
continues on ensuring that all tooling etc required for the monolithic
hang at LASTI is in place, and that parts are shipped at the US
sufficiently fast to avoid delays to the US assembly work.
- Glasgow:
Work is focussed on identifying the cause of the failures in the weld
test hangs at LASTI. In the meantime, preparations for the monolithic
hang continue, alongside preparations for the review.
- Birmingham/Strathclyde:
BOSEM assembly complete. We are studying the noise performance of the
BOSEMs . Production of electronics well in hand, and we are hoping for
approval of the one remaining design this week. We are working with the
US team to resolve the best way forward regarding the ESD design
following the review of the prototype.
- Overall: Thoughts are
now turning seriously toward the “end game” of the current project. All
three partners have completed or are well underway with production.
Live issues are.
- Resolution of the test-hang problem.
- Following up on the ESD review.
- Closure of the approval of the remaining electronic drive unit design.
- Checking the noise performance of the BOSEMs.

Operations Work
- HLTS
- Work has begun on helicoiling parts for the HLTS prototype. Large
parts that are at LLO have been cleaned. Small parts and hardware yet
to be cleaned.
- HSTS - HSTS FDR documentation ongoing.
Working on sub-assembly drawings and on adding the top level hardware.
Added the correct magnets to the test mass. Working on a new magnet
holder for the upper mass. There's also been work on updating the FEA
report. Work on updating MATLAB and Mathematica models to produce
seismic noise and thermal noise curves using the revised IMC/HSTS
parameter set is underway.
- Maraging Steel Blades - Two vendors are due to deliver prototype blades soon. Preliminary data looks promising.
Project work
- Quad alignment training last week at LLO. Visitors Joe Odell
(RAL), Jay Heefner and Norna Robertson (Caltech), Doug Cook, Betsy
Bland and Mark Barton (LHO), Brett Shapiro (MIT). Local staff involved
include Janeen Romie, Gary Traylor, Carl Adams, Matt Maxwell, Josh
Smith, Bryan Smith. Good transfer function signatures of the training
quad. Staff practiced how to interpret the transfer functions to
correct mechanical issues in the suspension. Work on alignment
techniques & equipment, including the theodolite took place.
- Face-to-face
with Joe from RAL last week was good for inventory control. A list was
made of items which RAL still needs to procure, RAL needs to have
modified, RAL needs to send, or the sites need to trade (stock that was
sent to the wrong place). Jeff has already gathered and sent the parts
which were LHO-to-LLO bound. LLO-to-LHO parts are being sent soon.
- Work
continues on AOSEM connector RFQ. AOSEM s/n 10 has been cleaned again
and is due to head into the vacuum bake oven at LHO by the end of the
week. At the beginning of next week, RGA scans will be run at one or
two elevated temperatures as part of the battery of thermal testing.
- Estimate received for the BS/FM and Quad storage containers.
- Helicoiling and cleaning for more bake loads continues when time permits at LHO & LLO.
- Work is ongoing on a DRD for the LHO fibre pulling lab and optics preparations at both sites.
- Norna participated in the monthly ALUK telecon.

Advanced LIGO Design
- We finished all the Final Design Review documents. (Luke Rodica, Muzammil, Guido, David, Dave, others)
- We have started HAM8 and HAM9 IO optical layouts in Zeemax, for baffles. (Rodica)
Advanced LIGO Acquisiton
- We traveled to Coastline Optics to demonstrate how to assemble IMC optic containers. (Luke and Dave)
eLIGO Comissioning
- I made a mode scan of the OMC to try to find a heater
temperature that puts the higher-order modes as far away from an
integer fraction of an FSR as possible. The data are noisy and the
effect small, but there is a trend towards higher temperatures being
better. (Kate)
Core Optics

Liyuan Zhang
- Like ETM04 and 2ITM04, one LIGO-1 fold mirror (FM03-A) has
been scanned over center 160 mm by the Jaz spectrometer for its HR
uniformity. The result of ~0.6% thickness variation from center to edge
is consistent with that of ETM04, indicating the ROC of ETM has no
significant influence in this measurement. A summary (LIGO-G0900938)
has been submitted to DDC. It seems that 2ITM04 is a particular one,
and comparing its uniformity result with previous measured
transmittance and AR reflectance is underway. With Rand and Margot,
continue to test the DW and FC cleanings with the AR coated ESW03
window at CASI.
Rand Dannenberg
- TDM DCN Spec sheet changes on AdL coating absorptions.
Partial defect counting microscope installation by Nikon in 015A.
Remainder and training on 10/26.
- France trip itinerary settled, for LMA coating contract.
- FTIR preliminary quantitative work suggests basic contaminant sensitivity will require additional optical fixture purchase.
- FTIR accesories researched, identified, ordered.
- Repeated
passes with Candace Younger on CSIRO latent defect contract language.
E-mail reply expected by EOB, call tomorrow Fri 10/16.
- P-Card forms filled out and delivered.
- CSIRO action item running compendium created. Working down the list.
GariLynn Billingsley
- Fold Mirrors have been shipped to CSIRO for annealing, we
are working on scheduling a joint phone call with Heraeus and CSIRO to
go over annealing cautions. Heraeus is concerned about the effect of a
long anneal on the absorption properties of the 3001 glass. Heraeus is
planning an experiment, to be based on the coating anneal, to see if
there is a change in OH content of the 3001.
- We have
Tinsley incoming inspection data on the Fold mirrors; in summary, it
appears that the o-ring contact does cause slight marking. The very
good news is that they did not detect any defects in the center using
fiber optic illumination against a black background.

Work Under Project Budget
OPTICAL LAYOUT:
- Mike is updating the H2 layout.
Work Under Operations Budget
- We have interviewed two candidates for the SLC ME designer
position, with the 3rd candidate scheduled on 10/15/09, and four
candidates for the designer/draftsperson position.
OUTPUT FARADAY ISOLATOR:
- Niem and Virginio measured the modulus of Elasticity of the
0.375 inch diameter rubber cord under load. The modulus is non-linear
with applied load, with an approximate quadric function. As soon as
safety approval has been obtained, the pairs of rubber suspension cords
will be adjust to the proper length under load to suspend the test
table for making vibration transfer measurements of the Output Faraday
Isolator suspension prototype.
- Mike will be out of town, and there will be no SLC report next week.

- A
TransMon_SUS design is being worked out with a new table optics layout,
Sam Waldman will soon provide a Zmax layout to Mike Smith and Ken will
convert it to solid works, do a layout, and mate the TransMon table to
the Telescope. A suspension approach is being selected from three
options, and one of these will help Matt with his work on the
suspension dynamics model.

LHO - Electrical - McCarthy
- Filiberto continued to lay tape down in front of electrical panels designating them as stay clear zones.
- Moved
TCS_ISS_DC_OUT channel from 3113 ADC channel 23 to channel 28. This was
deemed by TCS crew to be a glitchy channel. After rebooting its ioc the
TCS laser came back with a slightly higher power and the adc channel
now saturates at 11.5V dc. Apparently a gain was changed in the analog
ckt that did not account for a potential higher power.
- Replaced
BSC1 Magnetometer as a fix for drifting lines. Worked with Roberts S.
on ISCT4 Accelerometers. The table accelerometer exhibited problems
that were traced down to what appears to be a broken shield on the
cable. This cable was installed after the OMC was installed, so it is
not that old. Perhaps an installation crimp to the shield or with some
traffic behind the table it was damaged. Transfered the channel to an
old wire with a short extension added.
- Continued with AdLigo DC distribution options.
Computing - Barker
- Most of the week was spent moving the LHO CDS code from the
LDAS SVN repository to the new LHO CDS SVN server. Files were split out
into multiple repositories. The wiki user SVN instruction pages were
updated.
- Additional memory was added to the ops linux workstation.
LLO - Hardware - C. Adams
- Adligo Quad test stand - Setup and initial alignment of most osems complete (PUM osems remain to be aligned.)
- TCS - Working on electronics documentation verification.
- CDS DAQ - Test Rack 90% complete
Software - K. Thorne
- Framebuilder - Alex updated the framewriter software to
correct the reported sample rate in the trend frame metadata. Keith got
the backup GDS broadcaster working by resetting the Infiniband
connections on FB0.
- OMC->LSC RFM communications - Matt
Evans and Tobin Fricke added robustness and error detection to the
reflective memory communication between the OMC and LSC front-end
software. This is more difficult than in the past because the OMC DAQ
sample rate is twice as fast as the LSC. This change allowed use of the
version 1.1.1 RCG for the OMC code at LLO and has reduced the digital
noise to the needed level. A presentation is planned for next week's
CDS meeting. Code changes have been uploaded to the CDS cvs system.
Project: AdvLIGO Systems
SEI - B. Abbott
- The 8-Channel Valve Drivers are being tested. Things are
progressing well. I'm starting to make a block diagram for the BSC ISI
electronics that is required for the FDR. I have gotten a quote for the
longer L4C cables. We will re-use the circuit boards on the old cables.
The internal Pier Interface cable that goes to the Inductive Position
Sensor boxes needs an end termination.
- Mohana is making the front and back panels for her Coil Drivers.
SUS - J. Heefner
AdL SUS
- A potential problem was discovered with the Triple Acq
Driver board design. The OPA544 used as the power buffer in the output
stage is subject to output phase reversal when the common mode input
voltage is exceeded. The manufacturer of the part (TI) was contacted
and a fix is in the works. One channel of the prototype has been
modified and is being tested. Once the fix is verified, the design will
be modified and a production prototype built and verified.
- The LLO BSC Teststand is fully operational and is being used for the quad assembly training.
- We have begun to look at the vacuum cable fabrication task that we are now responsible for.
AdL DAQ
- The prototype IO chassis interface backplane has been
assembled and tested. We will now integrate it with the prototype ADC
interface board and test the system with an ADC and the front end
software.
- The DAC interface design is 90% complete. The board needs to be routed and then fabricated.
- A
minor dimensional problem was discovered with the prototype IO chassis.
Hamilton is fixing the design and is also making a new back panel that
will line up with the IO backplane slots.
AdL TransMon SUS
- Waiting for requirements.
ELIGO and AdL TCS
- Designed and fabricated chassis front and rear panels for the new QPD amplifier.
- Took a tour of the LLO TCS system
- Beginning a block diagram of the AdL TCS and controls
ISC - R. Abbott
- Finished design of Advanced LIGO Demodulator. Laying out the board now for build of final prototype.
- Found
that the limited isolation from LO to RF that is intrinsic to a diode
ring type RF mixer can lead to AM demodulation of the local oscillator
for the I phase of an I &Q demodulator. This is something that
should be kept in mind with respect to the initial LIGO demodulators.
The Advanced LIGO demodulators have 30 dB higher isolation, and are
thus far less prone to this noise mechanism.
- Working with
Suspension group on AOSEM design, and the in-vacuum cabling as relates
to the OSEMS in particular. We found a small detail relating to the
lengths of the pre-manufactured cables, that will require some
attention at the level of purchase order specifics.
- We
traced the recent failures in the OSEM cabling associated with the LLO
Quad to the fact that these assemblies were prepared as a stop gap, and
don't reflect any of the lessons learned in our Advanced LIGO cable
suite. No particular need for further attention.
- The ETM
quad transmission monitor has been re-packaged to allow use in-vacuum,
or in-air. It should prove a handy solution to much of our quad diode
needs, even beyond ISC.
AdLIGO Cable Plane - E. Brown
- Progress of the Cable spreadsheet database and documentation
work. When this information is complete it will allows us to generate
many different types of reports, for example:
- Cables per chamber
- Which cables on which flanges
- Total cables per site
- Just air cables
- Just vacuum cables
- Just Feed-through connectors
- Listing of cables and where they go
- What cables connect to which racks
So far, all of the in-Vacuum cables have been added to the spreadsheet,
(about 6000 rows of information ) but a lot of information especially
the lengths of each of the cables have not been available.
