Quality/Safety (Nolting)
LIGO Lab Safety:
- Bill
Tyler and Peter King are working on the final draft to the Laser
Recertification Training Program.
- In
conjunction with the recertification training, the agenda for the LSO
Workshop is being drafted. The workshop is scheduled to take place
at Caltech on October 20 & 21, 2009.
David Nolting:
- The
LHO 2009 Annual Safety Audit Report was completed and delivered to LHO
management for review.
- Work
continues on the Operations Safety & Environmental Protection Manual
revision.
LIGO Hanford
Observatory (LHO) and Interferometer Operations (Raab)
Summary of activities at
LIGO Hanford Observatory (compiled by K. Kawabe):
Squeezer update (D. Sigg, S.
Dwyer):
- We
saw some green light from the SHG scanning the cavity, with the
temperature controller reading 33 degrees C. We had to switch back to the
94.7 % reflector that came from AEI. We had swapped it out for a mirror
that we thought was 90%, but turned out to be HR. It seems like the
cylindrical lens might need to be adjusted if we want to improve the mode
matching. There were also some issues with the polarization which still
need to be sorted out. For now we just added a lambda-half plate.
- Started
the procurement of 2 LSC photodetector interface chassis. This is the same
circuits as in initial LIGO, but in a 1U chassis.
LIGO
Livingston Observatory (LLO) and Interferometer Operations (Giaime)
Enhanced
LIGO commissioning (Valera Frolov):
- The vertex section of the vacuum
system was vented to restore the ITMY pitch alignment with permanent
alignment magnets. The bias current was reduced to a small fraction of the
total range. The vertex was been pumped down and the ITMY remains aligned.
- The TCS electronics commissioning
has been completed. The TCSY beam was aligned to the ITMY using corner
Michelson interferometer.
- The HAM6 work this week included
changing the mode matching telescope, installing additional beam dumps,
and replacing the metal cable clamps with peek clamps. The new mode
matching solution was found after taking the beam scan data in HAM6 of the
beam propagating from TT1 to TT2. It was determined that a better MM
solution is obtained if the TT2 curved mirror (ROC 4m) is replaced with a
flat mirror. After replacing the mirror the visibility improved from
90-91% to 94-95%. We are going to remeasure the mode matching/visibility
with HAM6 under vacuum, to perform the mode scan, and to investigate the
effect of the better mode matching on the OMC alignment control in full
interferometer lock.
- The HAM6 door was replaced today.
The vacuum pump down has started.
LLO CDS
(Keith Thorne):
Hardware
- Carl Adams and Chris Guido
finished up TCS work. Chris installed beam tubes to prevent chiller
lines from falling into the laser beam and documented all changes to the
TCS ISS boxes (which were not in any current drawings). Carl order
serial cables to prep for migrating motor controller to Linux controls.
- Jeremy Birch finished reworking
the PEM electronics chassis for the vault, which has now been
re-installed.
- Mike Fyffe is helping to get
pinouts correct on PSL ISS MON channels into the DAQ system.
- The optical fibers required to
repeat the laser lock noise test done at LHO have been orders. This
will carry light from the optics lab to the MSR, where they will be sent
out the end stations and looped back.
Software
- Keith and Jeremy installed the
new tape library. Keith installed the Arkeia software and verified
that the tape library is properly recognized by the software. We
await delivery of a stack of tape media to do real backup config.
- Keith continued tests on new
server and sub-net configuration. An EPICS gateway was set up that passed
the EPICS variables and controls up to a workstation located on a
different subnet from the front-ends. Next steps are to verify that
an existing front end will boot off of a new file server and to start
setting up the new subnet on the switch.
- Keith installed right-click menus
on operator's Linux desktops and updated site overview screen to remove
remaining inactive EPICS channels and to add HEPI watchdogs.
- Keith worked with Dave Barker and
Jamie Rollins to explain the 'stdenv' setup for control-room scripts and
documented scalable font setup for Linux MEDM.

40-Meter
Interferometer (Adhikari)
Report for the week ending
9-10-09:
- In
recent weeks we had great visits from Jan Harms (U Minnesota) and Yoichi
Aso (U Tokyo). Jan showed us how to set up a quick seismic station to do
seismic huddle tests for our Adaptive filtering seismic sensors. We now
have 2 Guralp CMG40-T, 7 Wilcoxon 731A low frequency accelerometers, and
one Nanometrics Ranger SS-1. The huddle tests allow us to measure the
sensing noise limits of the sensors.
- We
also have a prototype 3-frequency EOM which was put together by SURF
student Stephanie Erickson. It uses a commercial New Focus KTP phase
modulator and an external RLC network. The complete package makes 3
resonances which have a 50 Ohm impedance on resonance. Tests with an OSA
verified the phase modulation response of the EOM.
- We
had a failure of the APC 2200W UPS that powers the 40m vacuum rack. It
failed suddenly after 15 years. We purchased the modern version of the
same model from APC and have everything running again. No vacuum hardware
was damaged by the UPS failure and our interlocks worked as expected.
- Peter
King came over and upgraded our PSL Reference cavity temperature box to
the LHO version (documented by H Radkins). This is to enable measurements
of the AC temperature fluctuations of the vacuum can so as to estimate the
frequency fluctuations in the 0.1-10 Hz band for AdvLIGO lock acquisition
estimates. During this process we became disgusted with the ancient MINCO
PID controller that is used in our PSLs and we have replaced it with a BNC
cable and a Perl script. This software based approach has a lower noise and
is easily tuned up from the control room.
Thermal
Noise Interferometer (Black)
- This week Eric returned from his
new-baby vacation. While he was out, Akira resuspended the old undoped,
optimized mirrors and re-took noise data on them with the new polarization
setup. He also devised a way to swap the mirrors in a single, marathon
24-hour session and installed the new doped, optimized samples. The noise
level is lower, as expected, but he needs to clean up some issues before
releasing the data. We will also need to contact Innocenzo to see if the
noise reduction is consistent with his theoretical models.
- Greg has been finishing
re-commissioning the cavity-assisted photothermal experiment in its new
location and is designing a thermal servo to keep the apparatus in
resonance over many-hour time spans. The chiller for the Michelson
photothermal apparatus went belly-up again, and he bought and took
delivery of a new one.
LASTI (Mittleman)
LASTI:
Jay and Rolf have been here
this week updating the frame builder, changing the clock rate on the ISI front
end from 2kHz to 4kHz and various other CDS upgrades. Due to the CDS work most
other lab work was not possible.
BSC-ISI:
Myron has installed the two
Trillium-240 low frequency seismometers on the BSC support beams. We plane to
use these to investigate feed forward schemes for additional ISI isolation.
CIT
Science Group (Weinstein)
No report
received for the current week.
Laboratory Computing (Anderson)
LDAS
SOFTWARE SYSTEMS (Maros):
- The
weeks efforts have focused on understanding why the diskcacheAPI continues
to coredump. Several issues have been identified, yet the diskcacheAPI
continues to core dump. This is a critical issue.
- The
development of the ldas-tools distributions is nearing completion. The
generation of the tarball is completed and is now part of the nightly
builds and unit testing. One error remains before this can go out as an
alpha release for RPM and debian packages.
LDAS

Advanced
LIGO and Supporting R&D (Shoemaker)
Advanced LIGO Management
Report covers time
period from August 31 through September 11
from Carol
Wilkinson
Project Controls
- Change
Request ACR-090010 to replace a damaged test mass glass blank was approved
for Core Optics, using existing funds allocated for glass procurements.
There is no impact to schedule or budget.
- Change
Request ACR-090019 for Facility Modifications and Preparations (FMP) is in
process. The request asks to transfer excess budget from install clean
rooms to cover costs for modifications for cleaning facilities. This is a
follow up to an earlier ACR that approved the new scope but did not move
the budgets in FMP. The request also includes a request for $120K from
contingency to pay for cost increases incurred when the inventory control
system was added to the JIRA defect tracking software. There were minor
schedule changes to define the review and bidding process for the vacuum
equipment design and fabrication.
- The
change request to augment staff for the project to produce technical
procurement documents and to support electronics procurements,
fabrication, and testing is in draft form. The new staff will support
active tasks as well as future tasks, as an aid in maintaining schedule.
The additional 24 individuals for 23 FTE-yrs of effort will be funded by
~$2.4M from contingency. The project has more than adequate contingency to
cover the staffing costs. (This request is matched by a similar request in
operations to add 7 individuals for ~6 FTE-yrs of designers and drafters
to help finish the design phase.)
Staffing
- Several
job ads and statements of work for the staff augmentation change request
have been posted and resumes are being reviewed. Three hires out of 31
project and development positions have been accomplished in the last two
weeks.

the CP cake tin and are going out for quote for 2 prototypes.
Opto Mech Meet
(Calum):
After a summer break we
started back up the opto-mechanical meeting. We covered:
- HAM 2 layout
- Layout of BSC's with ETM with ETM telescope layout, AdvLIGO Systems, BSC5-H2
Top Level Chamber Assembly
- Advanced LIGO Systems Drawings, D0901491
Systems Drawings
(Ed):
I updated all BSC (10 total)
Chambers System Drawings for H1 and H2 PDF files. I added the location of each
chamber with respect to the Stations (Page 1 of 4), I also added the BOM of all
components (Page 2 of 4).
Installation/Commissioning
Options (Mike):
Held a systems meeting to
discuss options for the installation and commissioning of AdL.
Gas Damping (Norna):
Norna Robertson and Jim Hough
revisited the question of residual gas induced damping of the test mass, based
on recent LISA project measurements (T0900416-v1). The tentative conclusion is
that AdL may require lower pressure in the corner station than is currently
achieved. Further investigation is required.

status page and the Interface Control page):
Nothing significant to report
Modeling and Simulation
From: Hiroaki Yamamoto hiro@ligo.caltech.edu
No report this week (travel).
Safety
From: David
Nolting dnolting@ligo-la.caltech.edu
- Participated
in TCS PDR
- Conducted
a safety inspection of AdL work areas and activities at LLO this past
week. Workers observed performing job task in a safe manner and
following safety rules. Housekeeping was in order.
Quality Assurance
From: Mick Flanigan flanigan_m@ligo-wa.caltech.edu
QA:
SEI:
- Reviewed
process flow and testing methodologies with the team working on the Large
Blades. We have resolved questions about how to measure the radius of the
blade throughout its length, and how to minimize variances at the blade
tip when performing EDM cutting. We still have a few requests for
information to resolve, including nickel plating suppliers that meet our
need for low phosphorus, as well as resolving the discrepancy between
potential allowable deviations on a blade surface which is in conflict
with allowed deviations across a matched set of blades.
- It
appears the Gage Pins I had ordered for the test measurements on the HEPI
Actuators came in but I am currently off site. As soon as I return I will
begin the tests. Hugh has ordered a 3x4 granite slab for LHO, will come in
handy for many other future tests as well.
COC:
Have been reviewing the DCC
documents related to optics coatings to prepare for the upcoming coatings
vendor visit.
ICS:
- Received
the new UI screens for catalog parts as well as the initial summary screen
and the subsystem screens. Looks very nice, cannot wait to deploy. We will
do another build later next week. The new development of the system has
slowed significantly, and we are putting much more effort in fine tuning
now. The team is doing a great job of reporting bugs, and we are tackling
the issues as we receive them.
- A
couple of major bugs found this week being fixed:
- Parts
references for loads prior to last build are not updated with the new part
key. References then lead to an error, unable to find part. We are
creating a script to clean these references and bring to the new
standards.
- There
seems to be a corruption in the parts for SEI. When trying to query SEI
parts, we return an error saying there is a duplication in the list and it
cannot pass the filters. Not sure where the duplication came from, but it
is being investigated.
- We
are still getting reports of bulk items being merged. A bulk part from LHO
is getting re-assigned to LLO because LLO has the same part entered at
their end. Still trying to validate this problem.

Prestabilized Laser
From: Peter King
<pking@ligo.caltech.edu>
Operations:
Chasing up a number of
quotations for 3mm InGaAs photodiodes
Project
- I
met with a campus facilities engineer, who had some experience with
designing/building some of the cleanrooms on campus, to discuss some
aspects of the Laser Area Enclosure design. He showed me some designs for
the cleanrooms on campus, what to consider ... etc. He also gave me a few
names of firms and cleanroom engineers to speak with.
- In
trying to get a better estimate of the Laser Area Enclosure, I have been
asking raised access floor vendors about factors to consider from a design
and cost stand point.
- I
made substantial revisions to the safety plan. I am currently working with
Bill Tyler to see if the changes are appropriate or not. The revisions
change the point of view from why to how.
Input Optics
From:
Rodica Martin <rmartin@phys.ufl.edu>
ELIGO Comissioning
(LLO):
We wrote a Matlab model of
the LLO OMC mode matching. From this, I determined the best change possible to
improve the mode matching is to replace TT2's 4m ROC optic with a flat mirror.
We purchased this mirror, installed it, realigned the beam into the OMC and
measured an improvement of 4-5%. (Kate)
Advanced LIGO Design:
- We
are working on documentation for the final design review. (Everybody)
- We
are updating HAM2/8 layouts. (Luke)
- We
continue working on the IO Zemax layout for baffle design. (Rodica)
Advanced LIGO
R&D:
We tested a piece of Class A
baked SiC at ~90 W input power and 1.8 mm diameter focused beam for several
days and the results are very encouraging: no outgassing has been observed
after the initial irradiation. The slight pressure increase when the sample was
first illuminated decreased slowly to the cold value while continuing pumping.
The temperature of the sample at the location of the beam (back side) was 240
C. (David F.)
Advanced LIGO
Procurement:
We received one bid so far
for coatings for the mode cleaner and the steering mirrors. The bid period will
close on Friday, Sep 18.
Core Optics
From: GariLynn Billingsley
<Billingsley_G@ligo.caltech.edu>
- Using
the Jaz spectrophotometer of Ocean Optics, a scan of 160 mm in diameter
has been done on the ETM04 HR coating at RTS. While the total 20K
reflection spectra of 550-1000 cm have been registered, treating the data
(~800M) is more difficult than I thought. Figuring out how to treat this
data is underway.
- With
Rand and Margot, continue to test the DW and FC cleanings with the AR
coated ESW03 window at CASI.
- ITM02
will be used to test out the new handling processes during initial
polishing of the Advanced LIGO Test Masses. After that it will be returned
to Caltech for disposition.
- Coastline
Optics has implemented a new mechanical lift procedure for removing blanks
off of the iron lap. They are working on a vacuum lift technique for
lifting off of pitch.
- Accounts
are in place for the renovation of 14 Downs to house the large aperture
metrology instrument. The facility should be ready well in advance of the
instrument installation.
- The
bare minimum of core optics for the one arm test is available by mid
September 2010:One each ITM, ETM, CP ERM.
- A
complement of spares by mid October 2010:an additional ITM, ETM, CP and
ERM.
- Dannenberg,
Flannigan and Billingsley are in Sydney September 21st for a coating kick-off
meeting. We have received the QA manual as well as a draft schedule.

Isolator
Ken is working with Niem on
an additional optical bench and the overhead rail for the 303 lab floor. All
the parts for the rail have arrived. Virginio is working with Niem to design
the mounting and attachment mechanism for the rubber support cords for the
Faraday isolator vibration measurement table. He will order the rubber cord.
Optical Lever
Andrea and Tara are trying to
determine the cause of the wide angle diffraction patterns that move when the
fiber from the fiber-coupled laser is moved. They are comparing the CCD camera
results in real time with the quad diode.
ETM Telescope
Ken has a preliminary design
of the ETM Tel/transmon table assembly. He is waiting for comments from Sam
Waldman before proceeding.

From: Vern Sandberg
<sandberg@ligo-wa.caltech.edu>
Operations: R&D, ELIGO DAQ,
and Electronics
LHO - Electrical
Engineering - R. McCarthy
- The
AC line power was off at the site Monday so DOE could performed
preventative maintenance on the circuit breaker that feeds LHO. The outage
itself lasted about an hour. Recovery back to a working interferometer is
taking longer much longer.
- While
power was off we helped Jonathan Hanks reorganize the Server Room. All
Cisco equipment including phone backbone are all in one rack and
Jonathan's servers are in another.
- We
tried to take advantage of the power outage to test the emergency egress
lighting for the required 90 minutes but alas the outage went way to
smoothly on DOE's side and will have to perform this on a Tuesday.
- Worked
with Filiberto on a new RF amplification circuit for SPOB 2-OMega board.
This is to replace a perfboard circuit that has been giving us problems.
The new board is ready to go but will wait for the IFO to return to
operation before installing.
- A
tilt meter has been installed on the LVEA floor for the Adligo OpLev group
to gather trend data. It is along the Y beam manifold almost to the TCS
equipment. New channels will be added to the 2k ADCU soon.
- Worked
with Hanford Fire engineering on flow testing our pumps: 1500 GPM flow for
a few minutes.
- Worked
with electrical contractor on facility items, e.g. the septic system.
- Pulled
the Anti-Image card from EndY suspension to investigate some oddities
Keita noticed. Examined the board and it tested okay. Took it back out to
Y-end with Keita could not re produce the feature he had observed.
Everything checked out.
- Once
again tried to convert our timing over to the new IRIG B server from
Symmetricom, but to no avail. Everything runs just fine but DTT can not
get real time data. Discovered that the IRIG-B time codes coming out of
the Brandywine VME clock module and the Symmetricom NTP-Server are
different. We suspect the Brandywine code is a legacy code and the NTP
Server is sending an updated version. Investigations continue.
LHO -
Systems/Software - D. Barker
- Building
of the new centos backup machine continues.
- Most
of the week was spent in recovering from the Monday morning power outage.
New OMC code was installed at LHO as part of this process.
- The
h1 epics gateway had problems during the recovery and we removed it from
the system. h1iool0 was returned to the CDS network.
LLO - Electrical
Engineering - C. Adams
Worked with the TCS team
(Phil, Koji, Chris, and much help from Rich A.) to bring the TCS electronics
online, tune them, and characterize them. The TCS laser beams (central,
annulus, and aiming) have also been realigned and adjusted after being powered
off for some time.
LLO -
Systems/Software - K. Thorne
Keith worked with Dave Barker
and Jamie Rollins to explain the 'stdenv' setup for control-room scripts and
documented scalable font setup for Linux MEDM.
Project: AdvLIGO Systems
SEI - B. Abbott
- Sam
is stuffing his LLO HEPI VME-to-pcie conversion boards. When they're
stuffed, he'll test them, and if they work he'll assemble the chassis.
Mohana testing her newest Coil Driver for the ISI tables. Emery has gotten
a good start with the in-vacuum wiring task. He got a bunch of information
from Carl Adams, and is on his way.
- A
third set of 10 Pier Interface Chassis have been stuffed. They'll be
tested soon. The GS-13 in-pod socket board is being stuffed.
- Monitoring
the work at DeLeon Enterprises for the 8-ch Valve Drivers. I have been
talking with Glenair about getting the GS-13 in-pod cables made. I have
put out an order for the GS-13 Pre-Amp boards. I have slightly modified
them to use surface mount components, where possible for ease of stuffing.
- I
have started working with Brian Lantz's Matlab files, and am finding out
the gain and whitening appropriate for the GS-13 chain.
DAQ - R. Bork
- Updating
LASTI CDS software, in particular new DAQ software and realtime software
which supports a new operational rate (4096Hz) for ISI.
- Installing
CDS realtime code revision 1.1.1 at LHO today for the OMC, same as
previously loaded at LLO.
- Starting
final drawing set for PEM connections and layouts.
- Looks
like Alex has worked out how to run our realtime applications with just a
minor patch to regular Linux. We have done initial tests using the OMC
applications and seems to work fine. We will load it on to the AdvLigo DAQ
test system next week and continue testing, but looks very promising. The
end result would be that a commercial realtime Linux will no longer be
required to run our systems.
ISC - R. Abbott
- We
have satisfactorily completed the ETM Transmission Monitor to the point
where it has been presented within the ISC team meeting. A few minor
component changes were suggested, and now we are working out the packaging
details for an in-air prototype.
- I
ran some electrical tests on the Advanced LIGO OSEM head that was recently
redesigned. I have taken data on the maximum photocurrent resulting from a
50mA LED current as a function of spacing and alignment. I am still musing
over the results.
- I
have been handing off information to Emery Brown, our new hire for cabling
needs. Things are going well, and Emery is coming up to speed quickly.
- I
ran some data on RF limiters to include as parts for the Advanced LIGO
I&Q demodulator cell. This design is next to complete.
- A
prototype RF Wavefront sensor has been constructed at initial LIGO
frequencies. The unit has been tested, and now needs packaging. We are
planning to try and get some run time with this unit in initial LIGO.
