General Items:
--------------
(Fred Raab)
Next Beam Tube Module
heats up! Bakeout of the Hanford Y1 beam tube module was started at 17:30
pm PST today. At 19:30 pm (now), all systems
behaving nominally. Tube
temperature is rising to 50 C tonight. - wea
Facilities:
-----------
(O. Matherny)
LHO New Construction
George Grant Construction Co. excavated for part of the footers for
the
Staging building and prepared the area for the septic system. Parts
of the
new roads and parking lot received the needed gravel base.
Old Item
LHO received permission from the State Health Department to use the
potable
water RO system and discharge the brine in to the existing leach field.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
HAM 8 & 9 work
HAM 8 was closed up (after installation of Support Table, Support Tubes,
and
Bellows) last week; diagonal portion of detector was pumped down and
HAM 8 &
9 were leak tested over the weekend. Results were discouraging--it
was
believed that 6 of 8 Bellows were leakers. These Bellows were then
re-installed. A second leak test once again showed quite a few leaks.
(It was determined that the Purge Air valves were the most likely candidate
for the leaks.) It now looks like just one of the Bellows is leaking--this
one will be replaced after HAM 7 work.
HAM 7 WORK
Installation of the Isolation Stacks, Optics Table and electrical cabling
began today. As of this moment is going smoothly. Once this work is
done,
leveling of the Optics Table is next and then the doors will be put
back on
HAM 7.
Later update -
The first seismic stack has been installed. The springs, seats, leg elements, optical table, and some cabling were installed in HAM7. This was nearly complete at close of business today (Thursday) with weights and clamps and closing the chamber set for tomorrow. - ghs
Optics & Lasers:
----------------
(D. Cook)
Most of this week was spent working with the IAS group at the X-End
station. It gives you a good feel for how long 2 1/2 miles is when
you run
back and forth getting things setup. It is a great hands on learning
experience. The setup is a two part operation as I see it. Part one
is the
setup of the reference line parallel to the beam tube and references
to the
beam tube monuments. This is done by using an optical transit square
and
laser autocollimator mounted on an electronic theodolite. This gave
a
target laser beam to which the installation fixtures could steer a
test
optic into it's position. The object was to locate the optic to within
3mm's both in the horizontal and vertical location, and within 10 arc
seconds of tilt. The air flow from the large soft wall clean room appears
that it may be creating some problems with the very sensitive and quick
response of the autocollimator. Some installation fixture changes will
be
needed. The basic process is going smooth, but as most dry runs it
produced
some items that need modifying. By week's end a lot will have been
learned.
The LVEA particle counts this week are running better than an average
of
class 6,000, with a lot of activity.
Computing Systems:
------------------
(C. Patton)
The permanent T1 line has been turned on and our router box has been
programmed for the new IP numbers. Twelve computers that were on the
old T1 line have been moved to the new T1 IP numbers. The DNS service
from Caltech has also been turned on. Our domain name is now "computer
name".ligo-wa.caltech.edu, e.g. our server is rainier.ligo-wa.caltech.edu.
The rest of the site computers will be moved to the new T1 line when
I
return from vacation and holidays, the week of Nov. 30th.
Two P5-90s have arrived from Larry Wallace. They will be equipped
with
modems, one already is, and used in the LVEA or Mid or End stations
to
allow access to the Caltech modem pool, for now, and when it is installed
to the LHO modem pool.
An ethernet connection to the General Computing network has been
installed in the LVEA Y section. The Bakeout crew will be using
it to
log their activities using the electronic web logging tool, elog.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
See above - ghs
Hensel Phelps had been formally informed that several
issues are
pending before our contract with them can be closed out. One of these
issues dealt
with the completeness of the electrical installation. The HPC project
engineer and office manager met with their electrical subcontractor
and after
an all day inspection at the site agreed that outstanding items as
noted in
our QA report needed to be completed. We subsequently
met with Parsons, HPC and LIGO and
agreed in principal on an approach to get all
of the outstanding issues resolved and the contract
closed out.
We are ecountering some delays with the contractor responsible for installation
of the laser
curtain. We had hoped to have this work and the cable tray installation
underway by now, as the
cabinetry for the optics lab is scheduled to arrive next week and we
would like to be able to
put it straight into the lab.
The networking room was reconfigured last weekend, with a few remaining
problems that are being
still worked on, such as cable labelling and making sure all of the
wall connectors are
functioning.
Vacuum Equipment (Allen Sibley)
After acceptance of the
y arm last Thurs. the arm was vented by PSI, and
work on the GNB valves was begun. The work has
progressed well with the
exception of fitting the flourel O-rings to the
mid point valves. The
O-ring arrived from MIT in time, however the
O-rings were not the correct
size. The mid station valves have been reassembled
and LIGO will need to
determine when these new O-rings can be installed.
All of the GNB valves
have been serviced and are in the process of
the 50 cycle test. PSI has
started the bake on the vertex and the x arm
manifold bake blankets are
being installed.
Educational Outreach.
Bonnie, Jonathan, and Mark attended the APS Plasma Physics Meeting's
Educational Outreach Day in New Orleans to set up a LIGO booth with
posters telling about
LIGO and free stickers for the kids. We also got some ideas about how
to do this better next time
(and a few counterexamples as well.) We took some pictures of our exhibit
with New Orleans
school kids that we will include in the next LIGO newsletter.

DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
40 m Interferometer (Nergis Mavalvala)
---------------------------------------
40m Prototype
The interferometer locks up fairly routinely for reasonable
stretches (several minutes at a time) after 8pm. We have
been measuring loop gains in all the servos to eliminate
possible pathologies there which may cause the interferometer
to lose lock. The issue of why it loses lock when the alignment
improves is still a mystery, but we're hoping a deeper look into
the control system and electronics will shed some light on this.
The optimal damping gains in the recycling mirror and beamsplitter
suspensions orientation controls were remeasured after we noticed
difficulties with locking with what were believed to be the best
gain values. The interferometer locks much better with the recently
measured values. Another mystery.
We attempted (again) to boost the low frequency gain in the lm
servo. Low frequency drift in the passive filter stage we added
was the problem, we will try to improve that shortly.

ASC Initial Alignment (K.Mason, M. McInnis)
----------------------------------------------
This week was spent at the
Hanford facility running through our initial
alignment procedures with alignment fixturing
and a LOS supplied by Janeen
R. The alignment test was done in the x-arm station,
following procedures
for alignment of the 4k ETM.
We successfully ran through the complete alignment
procedure, positioning
the dummy optic to its vertical and transverse
position with a scale
mounted to the fixture. We read the axial position
with a prism mounted to
the fixture, and set the angular orientation
to within 1 arc sec to the
autocollimator.
Several issues were brought out which need to be resolved:
1. We found a 10 arc sec error which appears
to be either within the
instruments, requiring a careful calibration
on an optic bench, or with the
parallelism of the autocollimator to the theodolite
line of sight.
2. Friction within the adjustment screws
of the SUS alignment fixtures need
to be reduced to consistently attain precise
adjustments and prevent galling.
In addition, we tested the autocollimators range
by autocollimating to a
PNI optic with 10% reflectivity @ 635nm at a
distance of 150 ft.
ISC control code development (MZ for Daw & Fritschel, on travel)
----------------------------------------------------------------
Daniel Sigg visited this week from LHO and helped us get our sw
development environment up and running, as well as get our GPS
timing system functioning. We should now have everything in place
to test the supervisory control code and GDS/ISC
communication.
Lock acquisition (Ware)
-----------------------
It's been bugging the heck out of me for some time now that, given
my
bright shiny new LIGO plant transfer functions obtained at the cost
of
three cpu-weeks of computation, and which for the most part can be
reconciled with the theoretical derivations, it's still something
of a crapshoot whether any individual feedback controller used will
be stable and lock. Why this set of poles and zeroes, and not
this
slightly different set?
SMAC ought to always have had an open loop gain
(optics*pendulum*controller, not just optics) transfer function
option, with amplitude AND phase, since that is, in the end, the
result which makes the design of feedback controllers an engineering
task, and not black art. So I've delved into the (largely
undocumented -- unless you consider the code itself the documentation)
FORTRAN and Matlab code to see whether this could be done, and if not,
why not. It actually doesn't look that difficult, so after a
few days
of study, I am about to attempt making the requisite changes to the
code.
ISC sensing table assembly (Zucker for Fritschel & Adhikari, on
travel)
-----------------------------------------------------------------------
With all the parts in-house, the second beamline (MC reflection) is
now
coming together. Alignment and testing of the EO shutter with
its
driver is underway.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- The frequency shifter used in the PSL has been aligned and has a measured
single pass diffraction efficiency of 90%.
- The PSL is now locked to the
reference cavity under the EPICS interface.
The laser remained locked overnight. A
quick in-the-loop frequency noise
measurement indicates that the performance is
consistent with the PSL
requirement of 10 mHz/sqrt(Hz), if not 2-3 dB
better.
- The cross-connect panel for the LLO 4k IFO has been wired and completed.
- New temperature stabilization hardware has been fabricated.
Installation
of the new temperature stabilization hardware on the LHO 2k IFO will
take
place in early-to-mid December.

Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Characterization of flat C continues. Low frequency results from
three
flat tests were grafted together with high frequency results from the
random sampling of FM2. The cutoff was Z8 (a combination of spherical
aberration and power). This composite picture of C was subtracted
from
a measurement of a pathfinder optic and compared term by term to the
CSIRO measurement of that optic. Power compared well, the mid
spatial
frequency terms were a bit off and the high frequency terms were within
a thousandth of a wave of the CSIRO result. We are now working
with
other three flat test methods to add certainty to the lower frequency
characteristics of flat C.
Delivery
We can deliver measured optics at any time given two weeks notice.
We
understand that a RM and ITM will be needed at Hanford by mid December.
We will continue to use the precious time between to characterize flat
C
and reduce the error bars on our measurement.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract-COC's coatings: Waiting to receive the next 4ITM from CSIRO
to
schedule the next coating run.
Characterizing coated and uncoated optics to be able to recognize coating
defects from polishing defects.
Received coated mirrors for M. Smith and Peter Fritschel.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
The shop has almost completed the fabrication of the double cavity
beam-dump. Ara (works half-time for COS now) is finalizing the layout
for
the SEI-mounted beam dump for GB RMHR3 in HAM3 and the LOS-mounted
beam
dump for GB 2K BSHR3P. Craig C. is working on the triple hinge joint
for
the cavity beam dump mount.
ARM CAVITY BAFFLES
Paul K. is in process of making detail shop drawings for the vertex
arm
cavity baffles.
ETM and PO TELESCOPE
CC Development, Mike S., Ken M., and Jonathan K. conducted a final
design
review on 11/12/98 of the completed working drawings for the ETM and
PO
telescopes. Recommended corrections are being implemented by CC
Development. Completed sets of working drawings for both telescopes
are
expected by 11/20/98. Preliminary results of the finite element analysis
of
the PO telescope have been received. The lowest fundamental vibration
frequency is on the order of 30 Hz, which is acceptable. The FEA of
the ETM
telescope in in process.

Seismic Design (Mike Fine)
--------------------------------------
1. Coarse Actuator Testing:
The full motions were tested last week. Hytec began by making
each
move request independently. All six DoF's were tested with substantial
margins of safety added to the range of motions. Independently,
these
motions can be as much as twice as large as the required, but do not
exceed the bellows requirements. Therefore, Hytec tested each
DoF's
to twice its required range and did not experience any mechanical or
electrical failures.
2. Coarse Actuator Development:
Hytec made corrections to the transformations routines. The desired
actuations are now being made for all rotation and translation
combinations. Hytec identified a problem in the software for motions
that require a single actuator to move a small distance relative to
the
remaining actuators and are currently addressing this problem and will
determine and implement a solution this week. They are also designing
a more visual interface for the motion commands, that will allow the
user
to command either relative or absolute position. The new interface
provides graphical gages that indicate angular and translational positions.
3. Air Bearing Testing:
Hytec successfully
tested both the lift capability and full range of
motion and showed that the air bearings are performing
as required.
Specialty Components has now been directed to
proceed with the production
order for the air bearings.

(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System (Daniel Sigg)
--------------------------------------
1. Work on the back-end of the diagnostics test tool proceeded.
Peter F. wrote a general purpose 2^n decimation algorithm
which includes an 42th-order FIR filter to avoid aliasing problems.
Ed D. is in the progress of wrapping up the Fourier tools
(power spectrum, cross-correlation, coherence, etc.). These
FFT tools will implement a heterodyne technique to zoom in to
an arbitrary frequency band. D.S. started writing the code
which stores diagnostics data in memory and saves/restores it to
disk. Looking into adopting the (new) LIGO lightweight data format
(XML based) as the native file format for diagnostics test
parameters, data and results.
2. Had some extensive talks about the future of the diagnostics
data monitoring tool (aka trigger tool, aka search tool). John Z.
agreed to lead the effort with help from Walid M. and Serap T.
The current thinking is to implement these data monitors on a
(multi) CPU shared memory system which gets the data from the CDS
network data server (aka frame builder) through a high speed link.
The system would consist of the following components:
1) A shared memory data distribution component.
a) Data producer API
b) Data consumer API
c) Distributed buffer management.
2) Online data receiver process (copies data from NDS to
shared memory)
3) Trigger generation API (send trigger meta-data to the
online database).
4) Trigger application environment interfaces.
a) for MatLab
b) for root
5) Signal processing library
6) Process control/Error Handling (undefined)
3. An important consideration is to define a (first) set of
physically motivated monitoring tasks, so that this effort gets
coupled with the detector shake-down as early as possible.
4. Went to MIT to discuss the ISC/GDS interface and help installing
a VxWorks system which will make it possible to run the excitation
engine in one crate and the ISC supervisory/data transfer code in
an other (connected by a reflective memory ring). We were able to
install, compile and load the complete GDS front-end software.
5. Also discussed the details of implementing a swept sine test and
the Fourier analysis tools: length of data sets, settling times,
windowing/overlap, averaging, measurement times, etc. etc. We agreed
on the basic software organization and who is writing what.
6. No final conclusion was reached on the graphical user interface
for the diagnostics test tool. Commercially available packages seem
to be either too specific or require a fair amount of programming.
A decision was made to cleanly separate the test organizer code
from its user interface, so that we are not locked into a solution
which might turn out non-ideal.
Physics Environment Monitor (Alex Marin)
-------------------------------------------
More work was done for the final design of the cosmic muon monitor.
For the Livingston site, a ruggedized weather station has been chosen.
The Davis weather stations will be mounted at the end stations.
A web site is under construction, which will contain
all the PEM
relevant information. At the present time, the deliver/order
schedule can be found at:
http://web.mit.edu/marin/www/PEM_Delivery.html
Shourov continue to work on simmultaneous seismic measurements at Hanford
and Livingston.
Matt S. is in Hanford this week His report follows:
> PEM activities for this week include the determination of accelerometer
> cable lengths to the new PEM racks in the LVEA. These
will be ordered next
> week when I get back to Boston.
> I have received the PZT shakers that I shipped here and have
unpacked them
> and put them into PEM storage. The Livingston DAQ system

One
> suggestion was to place them into the unused HAMS for the 2K
and 4K.
Optical Contamination (Daqun Li)
--------------------------------
All the three contamination cavities are back on-line with light
illumination. The initial ringdown and mode spacing data for
both
cavities 1 (with viton) and 3 (with Faraday) are well consistent
with the previous data of those two cavities. A few weeks is
needed to complete the qualification process of those two materials.
Ringdown and mode spacing data is still taking to qualify the empty
cavity (cavity 2).
Still working on the Loss Scanner to detect points of defects on
a 3" flat optic (T=1500 ppm) with the scatterometer under computer
automation.

============
- Reflected memory boards for Sun workstations being returned to factory
for
test.
- Work around using fast ethernet in place of VME to Sun reflected
memory is
nearly complete; getting sustained rates of ~3.5 to 4MByte/sec total
system
thruput with a single network attached. This can be scaled by adding
multiple
fast ethernet links.
- Have been experiencing problem of running multiple of the new 24bit
ADC
boards in a VME crate; turned out to be an error in the ADC manual
for setting
jumpers, but it caused delays in getting software done.
- Began writing software to interface GEO's Triana software package
to the
DAQS realtime network server.
Timing
======
- Driver software being written for the new binary clock GPS receivers.
- Received the first two GPS Receivers with the binary clock modification.
One is being tested at Cal tech, the other at Hanford. Three pairs
of clock
fanout modules are completed, one for each receiver and one for further
development of the Sync Error circuit.
Suspension
================================
- 10 Satellite amplifiers and chassis are complete and ready for shipment
to
Hanford. 8 will be installed as part of the 2K IOO suspension system
on
Nov. 30.
- DAQ daughter cards have been received and will be stuffed and tested
as
time permits.
IOO
================================
- Rack 2X6 cross connects are 95% complete and will be shipped to Hanford
for
installation on Nov. 30.
ASC/LSC
================================
- Lori has a full working version of the ASC front end software running.
This
version includes the ADCs, reflective memory, all filtering, which
is
selectable, and operator displays for controls and monitoring. Right
now
there appear to be no show stoppers for the LIGO ASC front end system.
A version of
the LSC front end system will be started next week.
MC LSC
=================================
- A second MC Length Demod board is being assembled so we'll have a
spare for
the IOO commissioning. A bias adjust and monitor are being added to
the
final version of the photodiode. This will also have to be added to
the
Demod board in the final version. The design of the MC Servo Amplifier
is
progressing. We are expecting a first article by the end of December.

Began investigation and evaluation of accounting software packages for Installation/Operations cost reporting. I have received some demo files and will be analyzing them to fit our criteria.
Created and implemented new excel based spreadsheet for calculation of monthly EAC for both the Facilities and the Detector. Decreasing the amount of manual calculation that is done monthly to determine EAC when a status of "no change" is submitted.
Finished reviewing of Hytec's MS Project schedule. All changes to dates, durations, and relationships of note have been incorporated into the current Open Plan Schedule for the Detector.
Finished producing the last first draft of the schedules and distributed
to the appropriate task managers.
>From: Florence Kaufman <fkaufman@ligo.caltech.edu>
No report this week.
Modification No. 13 is being issued to the CBI contract in the amount of just over $97,000 to cover several change order requests.
A Technical Review Board meeting will be held on Thursday, November 19 to discuss the LIGO position on fluporel O-rings for the midpoint gate valves at Livingston. There are several technical and contractual issues with PSI requiring resolution.
Representatives of Hensel Phelps toured the Livingston site on Thursday, November 19, with some of their subcontractors to try to correct some of the deficiencies discovered in the buildings. LIGO personnel will request a plan from Hensel Phelps to correct these defects.
The exchange of correspondence among LIGO, LSU, and the State of Louisiana regarding the Livingston access road is being forwarded to the NSF for informational purposes by Sandy Pool.
The State of Washington Department of Revenue has requested that LIGO submit forms to register as a business in the state. These forms have been forwarded to Sandy Pool for handling.
1.4.3.1 Systems Engineering & Integration (AL, BB, CC, JK, DC)
Reliability:
* LIGO Service Center Task #: 100096.11: 2.0
Hrs
Nothing significant to report.
* Met with Jay Heefner and Dale Quimette. Design status of CDS
ASC/LSC
remains unchanged. Reliability effort will remain suspended
until
sufficient design information becomes available.
ELEVATED PLATFORMS:
Preliminary effort was made to find an elevated platform to allow access
to
the BSC chamber. A pass through version is required for working in
chamber.
SEISMIC BALANCE WEIGHTS
First 10# weight was submitted to & approved by LIGO last week.
Production
was started and hopefully machining is finished on all 10,000# of weights.
Passivation should be finished on the first 1000# and this lot should
be
shipped to our Northern California vendor, for bake out, by Monday
11/23/98.
Balance to be shipped in 2000# lots every other week, starting in two
weeks.
X & Y-BEAM SPOOL BAFFLES(COS COC BAFFLE)
Detail part changes have been completed but shop drawing effort has
suffered
due to other priorities. Barring any new major interruption, details
should
be finished by Tuesday 11/24/98.
1.4.3.3 Modeling & Data Analysis (KB/HY/AL)
Kent Blackburn:
* Made two more revisions to the documentation for the GenericAPI.
* Began writing the requirements document for the ManagerAPI.
* Integrated new staff (Xiao Hu) into the
LDAS. Xiao will be our
database programmer and has already started working with me
on
getting DB2 on our system.
* Met with Roy Williams to discuss purchasing a DB2 license/software
for one of the LDAS servers.
* Met with Dave Hackenberg of Fore Systems to discuss potential solutions
for the LDAS network. An interesting feature identified is a
Gigabit
uplink in the 2810 switch that could feed the Beowulf with its
OS.
Phil Ehrens:
* Designed developed and implemented a self-documentation
method for Tcl/Tk scripts. The output format is HTML.
Features include a table-of contents linked to individual
procedures, and colored syntax highlighting of the Tcl
code blocks. Look and feel is highly consistent with
the LDAS GUI help system file format.
* Removed widget dependency from the "openLog" procedure
in the genericAPI.tcl script based on concerns expressed by
Albert Lazzarini regarding the robustness of the procedure.
* Began to install system software into the new standard
installation directory hierarchy using Ed Maros's build
maintenance system.
David Farnham:
* I have met with Walid to discuss the FCL API. I am now working
on
defining the functions which the FCL API should implement.
* I have been running benchmarks on the Beowulf cluster (mpbench and
other parallel code which I have come across) in order to test
the
stability of the new kernel (2.1.127) and to measure the performance
of
the cluster. So far the new kernel appears to be stable
-- there have
been no problems during a ~48 hour test (running parallel code).
* M27 has been upgraded to RedHat 5.2. I have also installed the
Tripwire (v1.3) security package.
* I have added a couple more test programs to the Generic API.
Xiao Hu:
* Read documentation on LDAS provided by Kent
* Read documentation on XML
* Installed / Tested Demo DB2 verions on LDAS NT machine
Bruce Sears:
* Studying and reworking the E-log system to make it more portable and
maintainable in preparation for installation at the Hanford
facility.
Adlib : multi-mode implementation (BB)
* Large Angular reflections from mirrors introduced.
* Mirror transversal displacements introduced.
* Beam-shift class is ready but we decided to keep it waiting outside
e2e
for the time-being in order to keep the code simpler by avoiding
one or
two presumably weak effects.
* Some more improvement in computational speed could be achieved by
cleaning
the code.
Adlib : Mechianics (HY, GC, SM)
* Giancarlo Cella has sent us a note summarizing his work. It is available
in /home/e2e/Software/docs/e2e/mechanics/.
* Somuya sent in a status report. He has started implementing his model
of
a suspended mirror in Matlab, and he will send us the code.
When
delivered, that code will be ported to e2e environment. This
module will
be used (1) for a fixed configuration - a simple suspension
mirror -
simulation and (2) for the validation of Cella's generic model.
Somuya's
dynamic formulation will be included in Cella's code where appropreate.
* The interface modification of e2e for Cella's mechanics module is
still
going on.
Alfi: (EM)
* Continued working on getting new version.
Admin: (EM)
* Compiled and installed several software packages
* Trying to figure out how to configure a cvs server and get it installed
on spica.
Misc: (SK, HY)
* Dr. Klimenko of UFL is visiting Caltech from 11/17 to 21. He presented
his idea of implememting fields, and the comparison with modal
model was
discussed and some simulation runs will be used to understand
the
difference.
* During the stay in Japan, Hiro visited SuperKamiokande site and gave
a
talk about LIGO status. He met Prof. Totsuka of ICRR and explained
LIGO
status and LSC. He finished the installation of the FFT program
on TAMA
machine and explained the physics and usage of the program to
TAMA
scientists.
1.4.4.2 General Computing (LW/TE)
MIT:
Nothing to Report
Livingston:
Modem pool should be online this week. Other network issues appear
to
have been resolved. Changes for the DNS tables to allow for direct
e-mail
services to the Observatory should be done by next week.
Hanford:
The permanent T1 line has been turned on. Twelve computers have
moved to
the permanent line. The rest of the computers will be moved when
Christine
returns the week of Nov 30th.
General Computing will have ethernet connections in the LVEA.
This will
allow the Bakeout crew and Detector Installation crews to use the electronic
logging tool, elog.
Two P5-90 will be used in the LVEA as GC computers for elog and downloading
documents.
CIT:
Installed the web application for reserving a document number in
order to do some parallel testing. The application is failing
because of
privileges.
Prepared a spreadsheet that is an electronic view of the DCC (all
directories with PDF files, all Access database files, and all the
WebBase web pages).
Updated WebDocs and installed November newsletter on the web site.
Continue work on getting software pkgs. installed on the new GC server.
The licensed pkgs. are taking considerable time.
Held number of meetings with the LDAS network planning is still going
on with
multiple action items on getting more information on equipment as well
as the
future plans of the WAN in the areas of the Observatories. The quotes
from
FORE and SUN have arrived.
We have received and installed multiple workstations and computer related
items. We now have a two digital camaras that people can check out
for use
in project documentation. Currently, one camara resides with Larry
W. and
the other with Elizabeth W.
Samantha working on docs and some minor s/w upgrades to the modem pool.
Performed some minor software upgrades to some of the networking equipment.
Working on the final procurements that are to be placed against the
5N510
account so we will be able to close that account in the near future.
