The Project Control Meeting
Agenda for Monday August 23, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #51, consisting of 10" optic BS01-B, was
released earlier this week.
Load #52, consisting of misc. Cavity Beam Dump and APS_PO Telescope
components is vacuum baking and is scheduled to be released tomorrow.
Load #53 is slated to consist of more COS stuff and should begin vacuum
tomorrow.
Optics:
---------------------
(D. Cook)
The BS-2k optic was successfully installed and aligned this week. I
had
a magnet come off during the first try and once again during the
reprocessing of the optic. This was apparently do to substantially
weakening the bond by allowing the magnets to get overly wet while
doing
the post-bake cleaning.
We now have the FMx in place in BSC7 and will begin the final alignment
this afternoon. Again this is a difficult optic to align due to its
weak
reflection at 670nm (laser autocollimator). The ITMx will also be
installed into BSC7 in the next few days. The vertical height setting
of
the BSC7 optic table will have to be adjusted at a later date as we
do
not have the controller cables installed as yet.
The portable CO2 cylinder was used to clean in situ optics for the first
time. Cleaning the BS-2k and the RM required about 1/2lb of liquid
C02 to
complete the job. The O2 monitor did not show a change during the
process. We will be cleaning the IOO optics in situ before closing
up
the chambers on Friday.
Mike Smith will be using a 940nM , 500mW laser for telescope alignment.
He has submitted an SOP for approval. The first use will be in the
optics
lab, but later to be used in the beam tube. If
you are bringing your own
laser safety glasses to the Hanford site be sure
that they are capable of
protecting you at this wavelength as well as
at 1064nM. The laser safety
glasses need to have a minimal OD of 2.63 @ 940nM
and an OD of 3.79 @
1064nM and be labled as such. I have had our
general use eye wear
certified to this and will be adding the labels.
Core Optics Support:
--------------------
(B. Weaver)
Tuesday, I assembled most of the components for the six beam dumps that
go in BSC 4, and on Wednesday Larry Jones and I started to install
them.
We were able to install four of the six horizontal tubes, leaving behind
the other two tube assemblies, and some glass beam dump assemblies
for
later attachment inside the chamber. These pieces will be left
in the
chamber for the next few weeks during pumpdown. The rest of the
pieces
for these beam dumps will have to be carried in through a different
route as the spool piece will close the door on BSC 4 today.
We also
installed the Recycling Mirror elliptical baffle while we were in BSC
4.
Today I went back into BSC 4, for the last time before the spool piece
is replaced, to clean up the mess we had left the day before.
This
included wiping down any horizontal surfaces inside the chamber with
damp wipes, where I picked up a fair amount of particulate dust, fibers,
and small foil bits.
Also on Monday, Bartie loaded the clean APS Telescope parts into the
vacuum bake oven, which will be released tomorrow (Friday). Currently,
we are finishing our final cleaning and air baking of numerous COS
alignment fixtures, in anticipation of Mike Smith's arrival for telescope
assembly here at LHO next week.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC5 work--
The Support Tubes and Downtube are installed. The Bellows are
fully
installed; Support Tubes and Crossbeam are now mated to each other,
via
V-Blocks. Work is now on hold to await word related to "Walker-ized"
Fluorel items (it appears that "Walker-ized" hardware is the culprit
for
excess water in the vacuum system). Next on the menu, would either
be to
continue installation (building the stack), or pumping down and testing
the recently installed Bellows.
BSC4 work--
Mark Guenther has gotten CAS online for BSC4. The elevation was
then set
on that Optics Table for Beam Splitter installation.
We received a our mobile CAS rack (for use out at mid and end stations),
and also have PZT's & electrical hardware for three of the four
chambers
which will require them (they are for the outstation chambers which
have
the Fine-X Translation Stages).
Computing:
----------
(C. Patton)
The GC Sun 450, fortress, has been rack mounted in the Computer User's
Room. The color Inkjet printer has also been moved into the Computer
User's Room. An additional UPS has been rack mounted in the GC
Server
Room, this weekend the Cisco Router will be powered down momentarily
in
order to transfer it over to the UPS.
I am still working on trying to get a service contract for the CDS and
GC ATM equipment.
Did the usual backups, ordered more supplies, and kept the GC accounting
paper work up to date.
Detector installation: Electrical feed thru on BSC1 has been replaced and the system is being leak checked now. Staging for the end station and installation of the crane socks in the end station portable clean rooms. Installation in BSC2 is on hold pending a decision on the accumulated water in the vertex.
Lasers and Optics: Helped P. King align the mirrors of the PSL
pre-mode cleaner. Checked the IOO suspension tower parts inventory. We
still need six more 1/4-20x.75L safety stop screws, but otherwise we have
all the parts necessary to assemble six suspension towers. Of these parts,
most of the stainless parts (~90%) either have been baked or presently
are being baked.
All the aluminum parts are scheduled to be bake next Monday or Tuesday.
(Sany Yoshida)
Beam tube bakeout: The DC power supplies have been ramped and tested in both local and remote operation. The supplies operate satisfactorily. The data collection system is operational with only very minor glitches that still need to be resolved. All safety procedures are being checked and implemented. A successful soft closure test was made on the end station gate valve. The mid-point gate valve was also soft closed and the vacuum system is ready for bakeout. (Allen Sibley)
Electrical installation: We have experienced two separate failures of the fiber optic network. Both were due to cables that quit working. It is very rare that a fiber optic cable would quit working - especially two in three days. It has become apparent that some guidelines need to be established with respect to access and handling. The most important thing for everyone to remember is - Do Not Fondle The Fibers! We are continuing to build up the racks at the end stations and the LVEA. A demonstration of the Proxima 9400 projection display was done in our control room. The picture quality is far superior to the model 9310 that we looked at previously. (Rus Wooley)
Weather Station (LSU's data) Link toLlivingston Ligo page added
but no data accessbile until J. Finney at LSU completes some programing.
CDS Controller rebooted for unknown reason. Rolf Bork, Dave
Barker and myself brought system backup but still problem with DCU at south
end station.
GRASP Work on changing calibration table and GRASP to accomodate
transfer function from shaker to seismometer output with small number of
frequency points. DCU having problems at end station. Due to lack of working
phone...progress on fixing at stand still. Phone crew working now.
Suspension Test Stand Sany and I hooked up satellite box and
located actuators and magnets...waiting for cables for actuators. (Anthony
Rizzi)
Facilities: Siemens, our contractor responsible for the installation
of the Building Control and Monitoring system has started to connect the
end stations to the corner station. The problem that they found was that
the copper wire (which they requested) does not provide adequate speed
for the system to work. They are presently looking into using one of our
fibers to interface with their system. A raised roof to protect the outdoor
flammable storage has been installed. This will not only keep most of the
rain out, but will also provide some shade for this area (overheating of
containers of volatiles has been a problem). (Gerry Stapfer)

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- SN #109, the laser with the new intensity control actuator, arrived
at
LLO just after the previous reporting period.
- SN #109 has been installed on the PSL/IOO optical table, the
phase-correcting electro-optic modulator has been installed between
the
NPRO master oscillator and the power amplifier.
The sample beam of the laser has been aligned into the reference
cavity. When the frequency stabilization servo was engaged, behavior
similar to that observed on previous occassions with SN #103a was observed.
Although when the phase-correcting EOM gain was increased, the high
frequency noise showed signs of suppression, unlike before.
Examination of the error point on an rf spectrum analyzer revealed
a number of peaks beyond 100 kHz, in the vicinity of the unity gain
frequency of the servo. It was assumed that this might be caused by
the
response of the high voltage EOM driver. The magnitude response of
the
high voltage EOM driver revealed a large peak at around 1.2 MHz. A
small
output compensation network was added to the output of the PA-85 op-amp,
along with a series output resistor to reduce the gain peaking. Whilst
this resulted in the loss of some phase, the frequency stabilization
servo
performance improved markedly.
Suppression over the 100 Hz - 10 kHz band was observed, with the
error point noise looking relatively flat. The spectrum looking like
the
one obtained with the LHO 2k IFO PSL. However, every now and then the
spectrum between 1 kHz and 10 kHz increases by approx. 5 dB and then
returns to its previous value. The cause for this behavior is not
currently known.
The 10-W laser remained locked to the reference cavity, overnight.
- Inquiries have been made with Lightwave Electronics about retro-fitting
the existing 10-W lasers with the new intensity control actuator. At
present they have sent out a number of rear panels for modification.
At
present the connector provided by Lightwave Electronics is a sub-miniature
4-pin LEMO. It was agreed that this would be changed to a standard
3-pin
LEMO connector.
Input/Output Optics -- Dave Reitze, UF

- Faraday isolator tweaked up to give ~ 35 dB isolation
- diagnostic pickoff beams aligned to IOT7, ISC7
- MMT aligned through MMT3; will align to RM today
- MC2 baffle glass baking for final installation tomorrow
- MC1 baffle installed
Quad sensor installed behind periscope on PSL table to monitor beam
drift/jitter.
- overall alignment (DC) stable since last Friday
LLO 4k
-IOO inventory completed.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We have been exploring the effects of two mounting techniques for a
fused
silica pathfinder optic. We are comparing the phase maps of a pathfinder
optic as supported by a V-block with maps of the same optic supported
by a
single wire. We have phase maps taken of the surface as well as maps
taken
in transmission.
The resulting phase maps are quite similar regardless of mounting
technique. The profiles may be dominated by the local thermal gradient.
There does appear to be a mechanical component to the change, but we
have
not been able to separate it out as of yet.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Coordinated with Sany/Livingston and Betsy/Hanford the last details
for our
trip to Livingston next week. (got fixtures made, procedures finalized,
materials ordered).
We are checking transmission on the witness samples of the COC's. At
this
time we are characterizing the transmission set-up, however, our
measurements indicate that the transmission on the 2ITM's and 4ITM's
are
within specs.

1. Electronics Rack:
Hytec has been working to complete the final electronics rack. Currently,
they are working to complete the rack wiring and assembly by Friday.
Next week they will begin rack checkout and software corrections.
A delivery date for the final rack is set for 9/10. Hytec will complete
the rack documentation before shipping the final unit. This will eliminate
the possibility of errors in the documentation when compared to the
actual
wiring.
2. Electronics Rack Documentation:
A complete set of drawings and documentation will be delivered to help
with
future CAS operations and troubleshooting. The current set of drawings
will be changed into a publishable state under revision control. Hytec
will
deliver the complete documentation with the shipment of the final CAS
rack
unit.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
Working on the trigger generation API. In
addition started the development of a new background
environment that is compatible with the root environment, and
should both make it easier to develop monitors under root, and
provide a direct migration path when the mature monitor function
is to be put into production. Wrote a version of the data
transfer routine that will receive multicast data using Daniels
multicast API.
Moved the code of the test point manager onto the configuration
manager CPU of the DAQ system. (Until now this code was running
on its own CPU.)
Made a draft layout of the graphical user interface for performing
diagnostics tests.
Made improvements and added modifications to multicast API.

but
waiting
for license key from wind river before we can run them (later today).
- Tried out new VMIC5579 PMC 64MByte reflected memory boards (for
ASC/LSC
comms with end stations ) on our MIPS
processors. Only processor which would work with these boards was the
200MHz CPU. All other
processors would fail power up testing. Contacted Artesyn, and turns
out
that the
boot flash in all our 175MHz CPU units have bad PCI bus info and need
to
be reloaded.
New eprom should arrive tomorrow. Will continue testing 5579 units
in
the one
processor we have which works.
2K One-Arm Test CDS: (DAO)
=========================
We split the design of the LSC Servo Amplifier and notch filter into

for
the LSC photodiodes to complete the three partially assemble units.
Timing System CDS: (DAO)
========================
I have not completed the testing of the two GPS Clock Drivers that
I
started last week due to heavy multiplexing of other tasks this week.
They
should be ready in a few days. The final version of the Clock Driver
is
in
PCB layout. We have four ISC clock fanouts assembled and ready for
testing.
I will ship them to Hanford as soon as I can get to them.

No report this week.From: Florence Kaufman <fkaufman@ligo.caltech.edu>
Worked on providing breakdown of 1999 budget for LIGO Operations to Sponsored Research. This raised issues as to the way the prior NSF award for LIGO had been translated into Oracle. Approximately $687,000 of the construction award is [already] being shown as awards in the Operations accounts. Several meetings have been held with Sponsored Research, Federal Accounting and Oracle consultants to try to resolve this issue.
Worked on preparing the monthly Operations report which has been a more time consuming process in the new Oracle environment.
From: Cindy Akutagawa <cindy@ligo.caltech.edu>
This week I have been attending training classes for the new World of Oracle: Monday was Human Resources/Payroll, Tuesday was WEBSTER (Warehouse Especially Built for STrategic Enterprise-wide Reporting), Wednesday I tried to use what I had learned... and discovered that all the wonderful things that it does for Campus does NOT work for LIGO! Thursday is OGM (Oracle Grants Management), Friday I will spend the day at "one-on-one" training classes on the Wonderful World of WEBSTER where I will take a copy of all the monthly reports I usually do for LIGO and beg them to show me HOW to get it done with the new (and VERY slow) WEBSTER.
Other things of note...
I received the June TWONK report from MIT and did the account distributing (the invoice from MIT (March-June) has already been submitted for payment).
While I was on vacation Barbara Kratochwill set
of a LIGO Account Translations (a listing of the ORACLE POETAs and the
LIGO Account Names to match them) and has put it on the WEB. Its location
is:
http://docuserv.ligo.caltech.edu/docuserv/home/accounts.html.
[Check this out! It should prove very useful for finding the new
account numbers! -pel]
While going through WEBSTER I found some things (salaries, travel trips...) that got transferred over into ORACLE incorrectly and I am working to get them sorted out and charged correctly.
No report this week.

in
order to transfer it over to the UPS.
Christine is still working on trying to get a service contract for
the CDS and
GC ATM equipment.
Did the usual backups, ordered more supplies, and kept the GC accounting
paper work up to date.
Fred R. has finally had some success with his VPN installation. The
VPN setup
has been a moving target, which has added to the difficulty.
CIT:
NOTE: All LIGO subnets have moved over to
the 100BT CITnet2000.
Barbara K. created a web page that maps our old LIGO account numbers
to the
POETA number. The URL is
http://docuserv.ligo.caltech.edu/docuserv/home/accounts.html.
A link to
the page is also available on the Internal Bulletin Board (a.k.a. docuserv
home page).
Created/installed a web page for the July LSC transparencies.
Added
links to the LSC page to the publication/presentations policy document.
Because of recent changes to the P documents, spent time updating my
publications list and checking the pubs and theses web pages against
the list.
Attempted to update PubDocs and ran into a yet unsolved problem.
The
upshot is that authors and keywords are lost for about 35 records,
mostly
invoices and will need to be reentered.
Suresh worked with Larry to resolve last Friday's disc failure on sirius
by
replacing it with the one sent by Sun Microsystems. Users in home2
were affected
the most by this downtime. Data was restored from the backup tapes.
Writing a shell script to check for malicious files installed by hackers
to
a list of Ligo hosts. This will be run as cron job notifying when such
event
occurs.
Performed some tests on third party backup software to work with new
tape robot.
Installed the provided changer device driver for it. Some preliminary
changer
assembly movements looks OK. The only problem is their excessive price
tag on
license key.
Made full backup of systems algol and spica in order to prevent from
accidentally loosing data due to random security break-in.
Usual support services to users.
We spent a great deal of time recovering from denial of service hacks
put on a
number of computers. In all so far 7 computers were infected (small
number
compared to the rest of campus) 4 of which were part of the CDS groups
computers. The e-mail server had to be partially rebuilt to resolve
the issue.
Kater is on its last leg. We have it up so the 40M group can continue
with their
work but it is not to be considered stable. Rolf and Jay are working
on getting
the kater replacement finalized. It should be finished by next week
as long as
the licensing goes well.
We have spent a number of hours working on Oracle and VPN issues. The
VPN
service has been getting upgraded on a daily basis for the past week,
which has
caused some problems on getting connections established correctly.
We expected
some problems but the rate of changing the VPN setup has been a little
high.
Presently, the new air-conditioning unit is being installed in the computer
room. This has caused us some delays on working on the servers and
networking
equipment but it should be worth it. The portable air-conditioning
unit has
become a necessity during the installation.
Resolved a number of PC issues and setups.
Working a number of procurement issues.
Rita Torres
Attended a 1-1/2 hr. meeting with the division for information on Webster and other Oracle systems. Obtained signatures for last week's Visitor Program proposal then copied Sponsored Research and the DCC.
For I. Petrac distributed the signed change orders for: Univ. of Michigan No. 2, Hytec No. 8, and Galli & Morelli No. 7. Formatted and LIGO numbered MOU Attachments A and Z to Louisiana Tech University.
For. E. Jasnow did edits to the contract with Richard Price constructing for landscape and erosion control at LLO. Obtained 10 bound copies of same; contract not yet issued to vendor. Also formatted letter to NSF Re: Landscaping proposal, pre-proposal conference. Prepared letter to MMR Constructors to transmit the executed contract for electrical contractor services for BT bakeout at LLO, FedExed the contract to MMR.
For M. Zydowicz did edits to the 13-page form FM112, Safety Audit, Hazardous Technical Areas. The form is now 11 pages after edits.
Irene Baldon
Worked on preparing the paper work for 7 new trips taken recently (7 Purchase Requisitions and 7 Advance Requests). There are approximately an additional 12 new trips in various stages pending completion of travel arrangements before the paper work can be completed.
Completed 48 Expense Reports, some of which were extensive, involving 2 or more pages each. Many of these reports were still not taped or completed by the Traveler, and required additional time for completion. Also worked on a number of problem issues which required a good portion of my time. There 24 are Expense Reports still to be done.
I continue to push for both Advance and Expense Checks already submitted. "The System" is extremely slow in processing these. Performed normal recording and filing associated with Travel and Reimbursement.
Had additional discussions with various ORACLE personnel. Travel has yet to be worked out and things are in a state of confusion. Things change many times from hour-to-hour. It is very difficult to get things through or out of "The System."
Prepared Travel/Vacation Itinerary for the Week of August 16th, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as from members of the staffs of each of the two (2) sites. I continue to do MIT's travel to the sites for installation activities.
Dorothy Lloyd
Dorothy's email failed so her report is being typed by Liz as dictated by Dorothy: "Nothing new to report."
Elizabeth K. Wood
Did personnel stuff.
Reconciled passport stuff.
Arranged meetings for a visitor arriving next week.
Acted as information desk for lost Caltech visitors.
Asked the phone office swap two extensions.
Attended a meeting on the new payroll system. Attempted to dodge bullets. Failed. Met with Alan Rice, Gary, and Phil to discuss the fate of the new, improved bi-weekly employee leave and effort forms. After the dust cleared, word came from on high that exempt employees do not have to sign their payroll sheets each payroll period unless they are reporting exceptional time.
Attempted to update LIGO's listing in the new Caltech 2000 phonebook. As per my email request to everybody who works in LIGO, please check your listing on the web at http://www.caltech.edu/cgi-bin/dirquery or in the old-fashioned paper version of the Caltech phonebook to see if you are listed correctly or at all. Of course since very few of you read this far in the LIGO weekly report, mentioning this here is pointless.
Discovered from Dorothy that in ORACLE, some POs have the old IFIS numbers
and some of the POs have the new ORACLE numbers. This makes matching of
paperwork from Phyllis and Dorothy's paperwork really difficult.
