The Project Control Meeting
Agenda for Monday January 18, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
To degas or not to degas. That is the question.
40 Meter: Recycling experiment clues and struggling to make it to the finish line
Blowing on the optics: CO2 jet cleaning while under suspension
LHO New Construction:
George Grant Construction Co. placed concrete for all the footers and
three sides
of the stem walls. The steel building shop drawings were submitted
to
Dillman-Lvaas for approval. As of this date the drawings have not been
returned
to George Grant. There is a six week delay from the time the drawings
are
approved to the time the steel arrives.
Water System modification:
Apollo is 75% complete with the water modification project. The 8000
gallon tank
was delivered but not yet plumbed in.
Compressors:
We requested Sullair to give us a quote for replacing the 10 compressors
that are
compatible with our environment. As of this date we do not have the
quote.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #11 consisting of three 3" IOO, one 2" and
one 1"
optics is loaded and will begin vacuum baking today. The three 3" IOO
optics
(SM05-1, SM04-1 and MCCM2K02-1) had been vacuum baked previously. They
require a
rebake as some of the standoffs glued to them had fallen off during
the
processing/handling that followed their initial baking. They were subsequently
repaired using the same procedure as was used to glue them intitailly.
Theories abound as to why
the standoffs are falling off and Qize Shu (U of
Florida) has included the 2" and 1" optics as
an experiment. The procedure for
glueing the "test" standoffs to these differs
from that used on the "real" 3"
optics in that the Vacseal (glue) was "degassed"
in a vacuum prior to being
applied to the standoffs. Additionally, the glue
used on the 2" optic was cured at
room temperature (same as 3" optics) but the
glue used on the 1" optic was cured
at 80C (soak temp of vacuum bake). Perhaps some
insight can be gained if the
bonding performance differs between these two.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Corey Gray met with Rich Riesen to prepare for SEI installation down at LLO.
Installation of Support Tubes, Support Table, and Bellows for HAM 10
was
completed on 1/13. The HAM 10 Support table has been leveled
and the Bellows
are in place with all seals leak checked. One of the Bellows had a
leak on its
larger flange, but with the help of O.S.U. post doc Robert Scholfield,
we were
able to re-install the Bellows and get it to seal.
For the 2k, HAM SEI Installation is close to being complete; here's
the
status of each chamber:
* HAM 7--- *~250 lbs of payload needs to be installed
*need fasteners for all payload
weights
*work on in-vacuum cabling
* HAM 8--- *~250 lbs of payload needs to be installed
*fasteners for payload weights
*HAM 9--- *~250 lbs of payload needs to be installed
*fasteners for payload weights
*install Air Bearings
*install hardware on Scissors
Tables
*HAM 10--- *Install Crossbeams
*Install SEI Stacks, Optics Table,
and payload
*install Air Bearings
*install hardware on Scissors
Tables
*All chambers--- need to level each Optics Table w.r.t. each other
(at least HAM 7-9), and then individually level
BSC: Numerous small tasks are being addressed by Larry Jones, Corey
Gray, Hugh
Radkins, and others. Most parts and pieces look like they will come
together in
time. Stack alignment still awaits the arrival of the truck 1-18 from
HYTEC NM
at which time the Adapter PLates will be aligned and then the remainder
of the
stack and Crossbeams will be installed.
Corey worked on vibration measurement equipment (namely, seismometer,
and Signal
Analyzer) with Rick Savage. Took some Vibration measurements out at
X-end
station.
Computing Systems:
------------------
(C. Patton)
A new AutoCAD key and a new license for AutoCAD 14 have been ordered.
I
expect them this week. The PC Photoreader seems to work on some
PCs,
but the PhotoShop software causes Windows Protection Fault problems.
Still no final resolution for that.
Rick Savage is pushing to get the LHO modem pool setup. There
have been
several discussions about what he wants the modem pool to be able to
provide. He may want to get an ISDN line put into his home or
possibly
go to 128k modems. His main goal is to be able to run EPICS MEDM
real-time screens from home to monitor and or control the PSL laser.
The electronic log software is being moved from the LHO email/web server
to the CDS server/gateway machine. The email/web server computer
was
not setup to support software development, regular log file backup
and
archiving, etc. The CDS computer allows LIGO access through the
T1 line
and supports the other requirements of the electronic log journals.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The cryopumps have been removed from ports Y1-2, 3, 4, 6, 7, 8 and installed
on
X 8, 7, 6, 4. The Cryopump at Y1-2 had to be sent off for repair because
of a
rubbing noise in the pump housing. CVI currently has the pump and they
are
evaluating and repairing it. The Turbos and cryopumps have been removed
on Y1-1
and 9. John Worden has given us (bakeout crew) two reworked (by Edwards)
Turbos
to replace the ones we were using for the bakeout. These two pumps
and the
cryopumps have been mounted on X1-1 and 9 and we are currently pumping
on X1
module with the Turbos (pressure is in the mid 10-7 range. The ports
at
Y1-8, 7, 6, and 1 have been re-baked following the equipment removal
and ports
Y1-5, 4, 3, 2 and 9 are ready to be baked (limited by aux turbo carts).
The DC
cables (34,000 ft total length) have been moved to X1 and terminated
at the power
supplies and on the tube. The blankets have been removed from Y mid
and corner
station end of the beam tube. The data system has been shut down and
Sun River is
in process of moving the data cables and boxes. We are currently moving
the
computers and setting up for X1 bake. The RGA has been removed from
Y1-5. The
trailers associated with the RGA and weather station have been moved
over to X1
module. Ed Watt will be out next week to complete the insulation work
on X1. Mike
Zucker is currently taking measurements on Y1 through the optical ports
on the
blanking plates installed for the bake. And yes there is light at the
end of the
tunnel or beam tube.
Optics & Vacuum Labs: (Jonathan Kern): Culligan has completed
the installation of the RO/DI system. It went on line Jan 13 and is providing
16meg-ohm water, which should improve over the next few days as the system
circulates. Another local plumbing contractor (Frank's) was hired, and
the tap water fixtures and heaters are installed and working in both labs,
as well as a drain line to the optics cleaning bench. He is also installing
a sink and taps in the staging building. His installer has done a very
neat and professional job. Gerry, Mark and Jonathan unpacked a 4x10' optical
table and man-handled it into the Optics Lab last Saturday. The Air-tech
flow benches which were
damaged in shipment have been inspected, and we're waiting to hear
back from the carrier. Bits and pieces of lab hardware continue to arrive.
I'm working on some bids for the PSL safety enclosure, and will circulate
options to interested persons soon.
Bakeout oven (Kerry Stiff): The bakeout oven wiring is complete and the oven temperature control system is being tested. The lifting fixture is enroute from the fabrication shop.
Computer network (Tom Evans): Tom has been working on Linux installation and on network problems.
Electrical Lab - (Juilien Svoboda): We are still working on getting the lab organized and getting furniture installed, as well as organizing documents for the test equipment. FO cable installation is continuing. The contractor appears to be having difficulty installing the armored sleeve material over the originally installed plastic jacketed cable because of the weisght of the armor sleeve. He also doesnt appear to be using any specialized tooling or equipment to do this, just 5 strong guys.
Beam tube bakeout preparation: (Cecil Franklin, Kerry Stiff): This week we finished installing thermocouples on X-1 module, this task started on 12-7-98 and was completed on 1-5-99. We began installing thermocouples on X-2 module, this task started on 1-5-99 and is now about 25% completed. The scheduled completion date is 1-15-99. We are working with Matt Smith to arrange the shipment of 9ea.of the 10 Pfeiffer Vacuum RGA's received from CBI. The RGA head and electronics will be shipped to Pfeiffer Vacuum for re-calibration.
Facilities issues: Hensel Phelps' electrical contractor, Wye,
has just about completed the QA rework including all of the additional
ground reference points. The mechanical QA rework is scheduled to start
soon. The conduits under the service road connecting the Beam Tube Enclosure
Vestibules to the pull boxes have been cleaned out. The contractor has
installed new pull ropes and sealed the end of the conduits. This was done
in preparation of the beam tube bake which will need these conduits for
electrical power. We received a proposal for B/T pest control, from a local
contractor - Arrow Termite & Pest Control Co. We have extended DiCioccio
contract to include the clean-up of the mid-stations.
Other: Travel plan are complete for Anthony Rizzi to make a
trip to Caltech on Feb. 1st to learn more about the 40m with a special
eye toward what it can tell us about the full scale LIGO. Particular attention
will be paid to the system-level feedback loops and CDS hardware issues
that might come up in initial troubleshooting.
The crime beat: Members of the Satsuma Hunt Club and their families toured LLO last Saturday. Everyone was very cordial and offered to help in whatever way they could to make sure there are no reoccurrences of the shooting incidents. Paul Coleman - Acting Deputy Inspector General, NSF, visited LLO on Monday and Tuesday with his assistant, Chip Warren. They also visited the Livingston parish sheriff's office and the FBI office in Baton Rouge to ask for their help should there be any future need. They expressed several concerns about the security of the site, such as the thickness of walls and doors and the need for on-site patrols.
We discovered that someone stole some of our landscaping! Eight of the azalea plants were dug out sometime in the recent past.
40 m Interferometer (Nergis
Mavalvala)
---------------------------------------
Since the previous weeks' observation that the
arm cavity losses
are a strong function of the beam position on
the test masses, we
have more carefully mapped out the postion dependence
of the losses,
partly with the goal of using this information
to "dial in" the
desired loss.
More work was done toward getting quantitative
results from the RF
probe sideband technique to measure the carrier
detuning from
perfect resonance. In the spirit of RF probe
techniques, some
hardware is being assembled to generate a 3*omega
local oscillator
so that we can use the already present J3 modulation
sideband to
extract length signals. This is based on the
so-called 3 omega
modulation method developed by Koji Arai in the
TAMA group.
We are preparing for a vent at the end of the
month to clean the
test masses and install a variable loss element
in the recycling
cavity. Severe personpower limitations are being
felt at the 40m
lab with any 3 of the 4 of us on travel or unavailable
for the
rest of the month. We are hoping to complete
some measurements
with the present lossy cavity system before the
vent, but...

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Interferometer sense/control (Zucker)
-------------------------------------
MZ is currently at Hanford. Site tasks for this week include:
-Receiving, unpacking and positioning IOT7 in the LVEA in preparation
for alignment check and CDS field wiring week of 1/17.
IOT7 just arrived and is being uncrated for inspection. Contrary
to
our shipping agreement the crate had clearly been unloaded and reloaded
on the truck at least once in transit; we haven't yet exposed any of
the internal
Shockwatch indicators but will consider making a claim if any are found
triggered.
-Assembly of MMT3 optical lever transmitter/receiver in preparation for field wiring
Scheduled for Friday 1/15
-Installation of HAM7 and HAM8 video cameras
Scheduled for Friday 1/15
-Calibration of LVEA/VEA initial alignment monuments using Y1 module
clear
aperture view.
Making steady progress. Due to insufficient time we will probably
not
be able to move the survey equipment to the mid station and get data
looking back toward corner. However the corner measurements are looking
reasonable. No way to know where we are with
respect to the Rogers
survey until we close the gate valve and pull
off the viewport to
calibrate out its (unknown) wedge angle (sort
of an unintended
double-blind test)
ISC fabrication (M. Smith)
--------------------------
I visited Southbridge Machine to inspect the optical lever support
wedges before they were painted. I found one discrepency with
one
drawing and need to add an additional hole. They incorporated
that
change easily the optical lever wedges for the 2K recyling mirror,
Beam
splitter, folding mirrors were shipped to Hanford Thursday Jan 14.
They
should take a week or so to arrive at the site.
The acoustic baffles for the ISC enclosure IOT 7 were ordered today,
along with the brackets to secure them. A marked up drawing will
be
sent to Valmex to incorporate the additional holes in the panels to
atach these brackets. We will have to drill holes in the panels
on the
IOT 7 enclosure when we go out to Hanford. The delivery is about
2
weeks, plus shipping, for the baffles and brackets.
All the quotes have not come in yet for the optical lever tables, legs,
support structures, and kinematic plates for the 2K ITMs yet.
They will
be in by Monday, Jan 18. Delivery is 6 weeks ARO.
IAS Initial Alignment (K.Mason, M. McInnis)
---------------------------------------------
(1/7/99 report)
---------------
The cause of the 85 microradian error found during the test run at
Hanford in
November was found to be caused by the mirror on the transit square
not being
square to the transit. The transit was calibrated by placing our laser
autocollimator on the mirror of the transit and plunging the telescope
in 90
degree intervals, adjusting the mirror untilwe were able to autocollimate.
We
then simulated in the optics lab at MIT an alignment and found we reduced
the
error to below 10 microradians. This remaining 10 microradians could
be the
accumulation of errors in leveling, autocollimation, and accuracies
of our
equipment and is well within our specifications.
All Initial alignment equipment was shipped to Hanford for use by Mike
Zucker the week of 1/11/99 and then for alignment of the 2k MMT3 and
Recycling
Mirror optics the week of 1/24/99.
(1/14/99 report)
-----------------
The design was completed of the optical flats and mounts used to align
tne
beamsplitters and folding mirrors. The mounts utilize the same adjustment
mechanisms and support structure as used in the PLX retroreflector
mount.
The ISCT7 layout drawing has been completed and is being detailed.
ISC fabrication & controls development (P. Fritschel)
------------------------------------------------------
o worked on tying up some loose ends regarding IOT7 (currently in transit
to Hanford)
o worked on the layout for the next isc table - ISCT7, which is the
reflection port sensing table
o ISC controls -- Got EPICS running on the MIT system, starting with
running the ASC controls database made previously by Lori. An undergrad,
Paul Grayson, started work this week with us -- he will be working
on
the supervisory controls for lock acquisition.
ISC supervisory controls (Ed Daw)
---------------------------------
This week I installed the first ISC supervisory
crate on the Hanford
data acquisition system. So far, the processor
reads the
data channels and sampling rates from the configuration
manager, and a GPS clock is configured to give interrupts on
each 1/16 second boundary. After each interrupt, the processor
reads the epoch (0-15) and copies data from the front end ISC
reflective memory loop to the data acquisition loop. Timestamps
and cycle numbers are written to the IPC (interprocess communication)
areas in the DAQ reflective memory area. Currently I am studying
the daq reflective memory protocol to ensure that I am writing
all the required information to the IPC area.
ISC wavefront sensing fabrication (Nergis Mavalvala)
------------------------------------------------------
A final (hopefully) iteration of the ASC wavefront sensing Guoy
phase telescopes for the 2k ifo is underway. Guoy phase telescopes
are being designed with the most updated mode matching telescope
(at reflection port) and beam reducing telescopes (antisymmetic
and pick-off ports) presently available.

Prestabilized Laser -- Peter King
--------------------------------------------
(Peter is on vacation this week.)
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
We analyzed the PSL beam profile measurement made in Hanford in detail.
We modeled the insertion of the three EOMs (electro-optic modulators)
and
their thermal lensing effect by an ABCD matrix for a medium having
quadratic variation of refractive index. The part of the ABCD matrix
representing the thermal lensing is based on our previous thermal lensing
measurement on the same EOM using a Schack-Hartmann wavefront detector.
(The quadratic variation of the refractive index was expressed by the
laser power using the previously measured relationship between the
optical
path length change due to thermal lensing and laser power.) The
calculation show good agreement with the measured beam profile. This
indicates that the PSL beam has been properly aligned and mode matched
to the EOMs. Also this result confirms the validity of our previous
measurement of the thermal lensing in the EOM.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Pixel size has been calibrated on the IR interferometer using a
translating knife edge over a 2" range. It would be nice to use
a
translation stage with a longer travel at some time in the future,
as
our present error is still 0.1%. The pixel size was found to
be .2665
mm/pixel, very close to the .2668 mm/pixel that has been used in all
previous analysis. An attempt was made to measure a static gauge
block,
but the choice of which pixel to call "edge" dominated the tolerance.
At least we are in a range now where we know that pixel spacing does
not
dominate the determination of radius of curvature. Probably our
next
challenge in this area is knowing the change in the radius of C, our
reference flat, as temperature changes.
We are currently measuring 2ITM01 and, unless re-directed to other work,
intend to deliver that along with a Folding Mirror to Hanford at the
beginning of February.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Continued evaluation of CO2
cleaning system. Performed a baseline analysis
of the surface roughness on a mirror (at JPL),
then repeatedly sprayed the
surface of the mirror with CO2. A repeat scan
of the surface roughness is
being performed at this time to see if any changes
in RMS are observed.
Also, cleaned a glass substrate according to
our present procedures,
performed a water vapor test to ensure the cleanliness
of the glass,
sprayed with CO2 and repeated the water vapor
test to see if the procedure
had any adverse effects on cleanliness of the
glass surface. The substrate
passed the water vapor test again, indicating
that the cleanliness of the
glass was not compromised by the spray of CO2
and that no apparent harmful
residues were left on the surface.
Next, I will evaluate different spray nozzles
for the removal of
contamination after a mirror had magnet assemblies
attached and baked.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
The double beam dump prototype is complete, awaiting vibration testing.
PO TELESCOPE

Global Diagnostics System
(Daniel Sigg, John Zweizig)
John Zweizig
I finished writing and debugging an interface between the Frame Class
Library (FCL) and my shared memory class. This is the fundamental
component of the Data Monitor Tool that allows the distribution of
Frame
Data via shared memory.
I modified and debugged a version of the Data Pusher process which
receives online data from the Network Data Server (NDS) and stores
them
into shared memory in Frame format. This version of the Data Pusher
is
somewhat different from the specification in that it receives the data
in
the CDS proprietary format and converts them to frame format, copying
the
result to the shared memory buffer. This is slower than the planned
direct
reception of frames into shared memory, but the frame distribution
is not
yet available and high performance will not be needed for some time.
I drafted a C++ environment for the background online monitoring
processes. The first use I put this to was to create a bit tester program
which I was able to run online to the 40m IFO.
I discussed needed/desirable modifications to the FCL library with Kent,
Walid, Albert, Dave, Ed, et al. FCL will be an important ingredient
in
distributing data to Data Monitors and must meet a few special
requirements placed on it by operation in the online environment.
I discussed and drafted guidelines for procedural programming of data
analysis functions with Bruce Allen and Kent Blackburn. These guidelines
are meant to insure that code produced by diverse contributors (LIGO
lab
scientists, LSC members, etc) can be easily integrated into the various
analysis systems that we forsee.
Daniel Sigg
1. Ed D. is currently at LHO developing the ISC part of the software
which reads and writes to the DAQS and GDS through reflective
memory.
2. Peter F. continued writing on the sine detection routine used by
the swept sine measurement.
3. Started writing the base class representing a diagnostics test object.
This base class will implement fundamental methods to handle the
excitation engine, to control the data input module (decimation,
heterodyne down-conversion, decimation, partitioning) and to call
the necessary analysis algorithms. All diagnostics tests (such as
swept sine, harmonic distortion, etc.) will then be implemented as
derived objects.
4. In order to be able to perform more general tests of the
diagnostics kernel, the emphasis of code developing has temporarily
been shifted to writing the command line interface first. The
interaction with the diagnostics kernel will be message based.
This cleanly separates the user interface from the actual diagnostics
code and will enable both the command line interface and the GUI
to use the same API.
5. Talked with Rolf B. about implement the GUIs for diagnostics tests
using resources from CDS.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
1. The delivery schedule can be found at
http://web.mit.edu/marin/www/PEM_Delivery.html
In short- All Wilcoxen accelerometers,and power supplies were received
for Hanford, BSC nd HAM interface plates were delivered to both sites.
2. The outdoor temperature sensors at Hanford are being installed
on
each building.
3. Looked at relocating the RGA from the top of the BSC chambers
to the
unused HAMs and the G ports on the BSCs. Material has been ordered
and will be delivered to Caltech within a week for cleaning then sent
to
Hanford for vacuum baking, starting around Jan 17. We are planning
to
relocate the RGA on WBSC2 to HAM 11 while we are at Hanford the week
of
Jan 24th.
4. We are continuing to organize the return of the CBI RGAs back
to
Balzers. Cicil found the protective vacuum tubes for the RGA
heads and
we are looking into getting the propper shipping crates.
5. We are preparing all the hardware for the test installation of an
seismometer, tiltmeter, shakers and accelerometers during the week
of
Jan 24.
Optical Contamination (Daqun Li)
--------------------------------
Cavity two with air baked steel has been relocked with initial
ringdown and mode spacing data consistent with the data prior
to this steel loading. Ringdown and mode spacing data will be
continuously monitored for four weeks before terminating this
testing.
The Faraday isolator has been taken out of cavity three and this
cavity has been assigned for acceptance test of CO2 cleaning
procedure. Right now, I am testing ringdown reproducibility by
disassembing and reassembling the cavity mirrors before doing the
CO2 test.
Cavity one (viton) containing moisture has been sealed for about
a week. Contamination testing will be resumed once the turbo pump
is freed from cavity three.

circuit boards was milled. Expect to staff and test them starting tomorrow.
Timing System:
==================
Completion of new Timing Board is still pending a board working at
Cal tech
with the ICS 110B. If we don't get it working this week we will take
all
boards up to Hanford with us next week and resolve the difference between
our tests and Dave Barker's. He has had two boards working on his test
stand. We are now trying to get information from ICS about the timing
for
driving a 115 DAC module for the GDS system. The timing and signal
pins are
of course completely different than the ADCs.
MC LSC:
==================
The MC Servo Amp is being layed out. All parts are on order. We hope
to
have a tested board by the second week of February. Will be installing
hardware and cabling at Hanford next week.

Simulation & Modeling
* adlib Modal Model code development
Biplab and Hiro worked on the implementation and validation of the
summation cavity for the Power recycled Michelson. Very close to the
final product.
* adlib dynamic loading
Ed fixed the dynamic loading option for adlib simulation codes to
work again, which broke when we updated egcs to 1.1.
* Collaborative efforts
R. Savage is going to come to Caltech in the first week of
February to develop the model of the PSL subsystem based on e2e. Peter
K
will work together.
A. Rizzi of Livingston will visit CIT in the first week of February.
He
is
interested to use e2e to simulate 40m experiment. After his visit,
e2e
softwares will be mirrored on the Livingston computer. A new account,
e2e,
has been created.
* Alfi
Ed worked on Alfi making it more stable, and included several new
features
to make it easier to use to handle complex systems.
* twiddle
Hiro got a request by Andreas Freise of MPIQ to let them use twiddle.
Jim and Hiro have started working to make the document up-to-date,
it
will
take a week or so, including new features added recently. After that,
twiddle will be delivered to GEO.
LIGO Data Analysis System [LDAS]
Kent Blackburn:
* Attended a teleconference with the LSC to discuss the common algorithm
library for LDAS, GDS, LSC, (others). The meeting concluded
with a
general agreement that a well designed procedural library written
in
C would be more desirable then an object oriented version.
* Met with Bruce Allen and John Zweizig to discuss algorithm programming
guidelines. After 4 or 5 iterations a draft memo is ready for
distribution
to the LDCG_LSC.html homepage.
* Met with LDAS, GDS members to discuss the recent evolutional changes
to
the FCL library. The week ended with a presentation to VIRGO
on these
changes which will require additional meetings in the future
to make
the
changes accepted or adopted.
* Met with a group of LDAS members to form the core database team for
the
group. I gave an overview of the role the database will play
in the
LDAS
and the software which is to be implemented to interface with
the DB.
The
meeting is to become a weekly event.
* Met with AL and Bruce Sears to discuss the possibility of Bruce
heading
up the high level command language scripts for use in the ManagerAPI.
This
will involve flow control and close work with the managerAPI
software
development. Bruce seems eager to take on this project.
* Reviewed a number of resumes and carried out phone interviews as
the
search
for qualified C++/Unix programmers continues.
Ed Maros:
* Looked at ways to encapsulate ODBC in C++
* Decided to use the class definition supplied with wxWindows as the
design
of the classes.
* Started to write code to implement the classes described in the
documentation.
Dave Farnham:
* This week I have been working on merging the changes I made to FCL
v1.01
with FCL v1.11. I have also participated in a teleconference
with
VIRGO
to inform them of these changes and to determine this effects
their
code.
* Additionally, I am now using the CVS repository on spica.
Phil Ehrens:
* Continued to work on the managerAPI.tcl.
Logging and queue management are functional,
assistants can be spawned and killed.
* Redesigned the assistant manager API as a procedure
in the manager which dynamically creates the asst.
managers from a template. The assistants exist in
their own namespace and can delete themselves.
Xiao Hu:
* Performing DB2 table altering test
* Studying DB2 CLI (ODBC) interface
* Reading some ODBC C++ class materials in preparation for a
object oriented metadataAPI C++ layer
Anderson:
Continuing to replace Beowulf cluster hardware and develop automated
tools for cluster system administration, e.g., the ability to
automatically
add/replace a node to an existing cluster in ~5min.
Lazzarini: Completed draft version of Preliminary Design Documentation.
General Computing
MIT:
Nothing to report.
Hanford:
The LHO modem pool hardware and capabilities requirements are being
discussed and a resolution trying to be reached. There is a request
to
provide both 56k modem ports and ISDN ports or possibly going to 128k
modems. There is a request to provide speeds and data transfer
capabilities to allow display and update of real-time Unix MEDM screens
on remote PCs through the modem pool.
Sean at CIT is working on getting more details on the hardware
limitations
of the Livingston box to make sure the requests can be accommodated
if
approved.
Livingston:
We have mainly been tracing network problems, and also installing Linux
on a PC.
CIT:
Full backup of server spica was performed. There is little bit of work
to be
done for the daily incremental backup of spica remotely from sirius.
Suresh and
Ed Maros are working out the logistics.
Created new email alias called ligo-all which includes cit-all, mit-all,
llo-all and lho-all. There are more changes going to be made to the
mail
aliases
which include starting the forwarding of mail to ligo-la.caltech.edu.
When
testing is complete the users in Livingston should be getting all of
their mail
locally. We will then start the same process for Hanford.
Installed new printers and plotter drivers in couple of PCs. Supported
users
for their email problems and also restored their deleted files from
tape
backups.
The ASX 1000 switch has arrived and is installed. Presently, installing
the OC12
board and connecting it to CACR's unit. We hope to start migrating
the
200BX
connections to the ASX 1000 in about two weeks (on a weekend).
Gone through a major session with SUN concerning a number of purchase
orders
that they had inadvertently canceled because of hardware changes on
their
product. Hopefully, things have been corrected and we should start
seeing
equipment in about a month. Phyllis is keeping track of things and
trying to get
a higher priority from SUN put on the orders.
A number of license renewals have been installed along with a complete
rebuild
of a system in one of the labs that lost its OS from the power hit
we
had last
week.
Everyone has been working with a number of PC issues. We have lost two
of the
P5-90's and moved their functions to other machines. The computer for
the Amaldi
conference has been setup. Sam is working on getting a PC setup with
a
scanner
and CD burner for general usage.
Suresh and Sean are working out the logistics to get kater upgraded
for
Wilson
House.
Babara has worked on web application for reserving a document number
so
the
requester id can be entered directly without using the pull-down list.
Wrote a Visual Basic program to load a text file of addresses into
an
Access database. The database will be used to produce mailing
labels
for
the Amaldi Conference poster. Installed a number of web site changes
including
SURF projects for 1999.
Dorothy Lloyd
On jury duty.
Irene Baldon
DECEMBER 16, 1998 thru JANUARY 6, 1999
Please note that this report is for 10 days, excluding Holidays and 1 day vacation.
Worked on the ever present backlog of paper work for various trips taken recently (31 Purchase Requisitions and 22 Advance Requests). There is 12 additional new trips pending completion of necessary paper work. Also worked on the ever present backlog of Expense Reports (101 Expense Reports). Most of these reports required extensive taping and typing of the report itself. The backlog is slowly but surely going down.
JANUARY 7, 1999 thru JANUARY 13, 1999
With a deadline of Friday, January 15th, for a zero backlog of expense reports, with the help of Liz, Rita, and Joann worked on the ever present backlog of paper work for various trips taken recently (25 Purchase Requisitions and 17 Advance Requests). There are 7 additional new trips pending completion of necessary paper work (still in various stages of reservation negotiation). Worked on Expense Reports and completed 43 Expense Reports (mostly problem or foreign ones) myself. While Liz and Joann worked on 36 domestic trips which I scanned as quickly as possible to get out speedily. Rita has been doing the copying and mailing. Most of these reports required extensive taping and typing of the report itself. This will enable me to do a speedier audit and only require changes when necessary. If you are not sure of the per diem, or anything else, please leave it blank, as well as the totals at the bottom, and I will fill it in. I will now be doing auditing of expense reports and the necessary paper work on new trips, plus recording and processing checks, foreign trips, visitors, etc.
Performed miscellaneous duties as requested by various
members of the LIGO Project here at Caltech, as well as for members of
the staffs of each of the two (2) sites.
