LIGO Hanford Observatory (LHO) Operations


Facilities:
-------------
(O. Matherny)

New staging Building:  The old construction trailer that is setting in
the new staging building parking lot is becoming a maintenance liability.
The wind likes to rip the siding and the roofing off, and the mice find
it as an excellent breeding place. For those reasons we will be removing
it from the LIGO site.

Compressors :  There is a purchase request at Caltech to buy five skids
of compressors to replace the ones that can place oil in the air stream.
Net cost to LIGO is approximately $37K.

Bake Oven:
----------
(K. Ryan)

LHO Vacuum Bake Oven A load #46 consisting mostly of COS Beam Dump parts
was released Monday 7-26-99.

Load #47 consisting of 10" optic 2ITM04-C and three ETM Telescope lenses
s/ns E980328-001, 2 and 3 was released today.

Load #48 consisting of more COS Beam Dump parts will begin later today,
7-29-99.

A periodic routine remeasurement of the pump speed of the RGA port as
seen by the oven chamber revealed an inconsistency that may affect the
outgassing rates calculated for loads #29 thru #46. I will recalculate
each of these individually over the next few days but so far it doesn't
appear to threaten the pass/fail status of any of these loads.  To be
safe, the post bake scans for these loads will be resubmitted to Dennis
C. and/or Stan W. for rereveiw using the corrected calibration factors.
 

Optics:
---------------------
(D. Cook)

We spent a lot of time this week realigning the FMy and the RM-2k. The
RM went well using the PLX periscope for the first time. M. Zucker and
K. Mason heading up the task. The FM presented further problems as the
laser autocollimator return signal was too weak to pick up. We used two
different autocollimators for the task, with the same results. We were
able to walk the signal back to the autocollimator by using an alignment
target. With this method we are probably within <50u arc seconds. Ken and
Mike installed the optical flat and the PLX in preparation for the BS-2k
alignment. With the help of several people, and some additional changes
to fixtures, we managed to install the BS-2k. Thanks go to Steve Penn,
Phil Willems, Bill Kells, Dave Shoemaker on the autocollimator, for
supplementing the regular crew.

Core Optics Support:
--------------------
(B. Weaver)

This week, I have been doing a lot of paperwork to straigten out the
numerous travelers that contain the billion COS Beam Dump parts. Over the
last few weeks, the travelers have come to look like treasure maps,
with arrows and lines pointing and connecting notes, dates, and
signatures. I've obtained the framemaker files of these travelers from
Mike Smith and have reworked them so that now they are understandable and
can better serve their purpose.  Mike has agreed to send me travelers as
framemaker files from now on so that I can rework them as I see fit and
months from now, they will still make sense.  This makes life a bit
easier on the vacuum bake oven people as well.

We loaded the current vacuum bake oven load with the ITMx and the three
lenses to be used in the ETM Telescope Assembly.  Today, we will unload
these items and reload with 8+ COS Beam Dump tubes and some misc.
hardware.  We will begin to assemble the BSC 4 beam dumps within the next
few days.

Seismic Systems:
----------------------
(C. Gray & H. Radkins)

BSC6 work:
After leak tests, and a little bit of extra bolt-tightening, all Bellows
seals passed with flying colors (that makes us 2 for 4 on getting all
Bellows to pass on the first run for the 4 BSCs worked on thus far at
LHO).

BSC5 work:
Scissors Tables have been installed and clamped down;  we are now waiting
on the delivery of the Fine-x Translation Stages (which are slated for
arrival at LHO Monday afternoon).  Other than that, continuation of
staging all items needed for work out at x-mid continues.

BSC4/CAS Electronics Rack:
Tests were conducted to check the settings on the Coarse X-Y motors; this
is needed to determine what type of software upgrade we will need from
HYTEC.

HAM10, 8, & 7:
Elevations for the Optics Tables in HAMs 10, 8, & 7 were checked and
adjusted.

Computing:
----------
(C. Patton)

A new Sun 450 computer has been setup.  This computer is intended to be
used for all CPU intensive data analysis done through the GC network.
This will take the load off the server and help cut down on user caused
server crashes.

Jill's NT computer now has limited network access.  Turns out there may
be a compatibility problem between the NT OS and SAMBA, the UNIX/Windows
network server software.  Larry Wallace has a fix for me to try.

With all the visitors here this week, I have spent time helping visitors
find places to connect laptops, find places where they can sit and work,
added several new user accounts and dealt with problems from users
overloading the server.  I have helped with questions about LDAS
connection to GC printers and etc. and attended a meeting on LDAS, CDS,
GDS, and GC application software compatibility.

Larry Wallace was able to get a modem connection working from his
computer at Caltech to our modem, however, I haven't been able to
reproduce that here.  Spent several hours testing with Richard
McCarthy's and Rick Savage's help, trying to find out if the problem was
with the phone system or the modem or the modem router.  It appears
there are problems with all the systems.  It can take several tries to
get the modem to answer because of the phone system switching between
lines. Once the modem does answer there are problems logging in to the
server and problems trying to run email and web software.  More testing
is needed to pinpoint the fixes.

Electrical & Electronics Systems:
---------------------------------
(R. McCarthy)

Installation of the 2k suspension electronics has started.  While putting
in the cross connects it became painfully obvious that the single mode
fiber optic cable was in the way.  Thus,  we spent the warm Washington
day pulling the fiber back to the man hole outside the building and
minimizing what was left in the rack.

Hooked up the Beam Splitter Mirror to the controller and verified
operation for Doug Cook.

Assembled and ran Data Acquisition cables for the Mode cleaner
electronics in the PSL enclosure.  Will work with Rana today to determine
which channels he is interested in.

Replaced the cable trays at the Y-Mid station that had been removed for
seismic isolation stack installation.  Removed cable trays in the X-mid
to facilitate installation of seismic isolation work.

Fixed problem with the MC2 controller.  Found a bad voltage regulator in
the satellite module.

It is believed that we have finally fixed the problems with the well.

Installation of phone lines and numbers to the Mid and End Stations are
complete.  The installation guys can no longer hide from outside calls.
 

Physics Environmental Monitoring:
---------------------------------
(M. Lubinski)
 

Matt Smith was here this week and we have installed and set up several of
the RGA computers.  We are continuing to inventory the PEM equipment on
site and going over the installation process.  Channel verification is
also being done as we hook up instruments and start to collect data.
 


LIGO Livingston Observatory (LLO) Operations



 

Detector installation: BSC#1: Installed locally made safety cat-walks, removed dome, installed upper cleanroom sock with bungie cords, installed platforms, removed D-nozzle conflats, installed Support Tubes, installed Downtube assy., torqued all bolts per procedure. Installed support tube small bellows and torqued, positioned large chamber bellows. Installing V-blocks today and will be
installing large bellows to chamber tomorrow. All equipment necessary to complete BSC#1 have arrived except for 16 epoxyed springs. (Rich Riesen) We are now baking small optical support system parts. (Tom Evans)

Beam tube bakeout: DC cables for the x-2 BT bake have been installed. All cryopumps have been installed and leak tested and run successfully. Problems are being experienced with the data acquisition system and are being worked. RGA is installed and leak check is under way. The bellows on BSC-3 have been leak checked and found tight. Vertex is at atmosphere and is being purged. (Allen Sibley)

Computers: We are in the process of installing Solaris 7, and are updating third-party software in the process, wherever possible.
We have ordered an 18 Gb disk for user files. (Tom Evans)

CDS installation: Installed a new crate for Anthony to replace the ones that were needed in Hanford. Generated a list of cables that need to be pulled from the Mass Storage Room to the LVEA. Cable is on order. Calibrated all the vacuum gauges in the corner and end stations and verified the readouts in the Control Room. Rewired all the gate valve signals. Verified gate valve position indication in the Control Room. Moved ATM switch from the Mass Storage Room to its permanent home in rack 1X22. Installed cross-connection panel in IO rack (1X4). (Rus Wooley)

Site infrastructure: Siemens Inc. has started to connect the end station's building monitoring and control data to the central control system which is located in the Control Room. This was one of the construction activities which was still outstanding and could not be completed until the copper wires were available at the end stations. (Gerry Stapfer)

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------

ISC supervisory controls (Daw, Fritschel)
-------------------------------------------
This week I worked with Peter Fritschel on the ISC supervisory
software. I wrote state code to monitor the state of the
gds test points and excitations (which ones are active) and worked
out the implementation of reflective memory interrupts from the
ASC front end triggering 16Hz monitoring of the data. I have also
been assisting my student John Leffingwell who has almost finished
writing driver software for the picomotor controllers.

In addition, I have been studying the transfer function of the
BSC seismic isolation stack (Eric Ponslets model) with a view
to building a bank of IIR filters that represent the transfer
functions from different degrees of freedom of ground oscillation
to the resulting motion of the optics table. This work is with
a view to generating simulated data for the motion of the ligo
mirrors in cooperation with Sam Finn.

IAS Initial alignment (K.Mason, M. MacInnis)
---------------------------------------------
The last two weeks have been spent in Hanford aligning OFy, FMy, RM,
OFbs, and BS optics.  Problems were encountered with the y-arm fold
mirror in which we were unable to get enough reflectivity off the fold
mirror to do the alignment.  Several schemes including using the laser
autocollimator from Louisiana were attempted, but we were still unable
to realign the optic. We are investigating increasing the power of the
autocollimator and varying the wavelength slightly.  If neither of
these approaches work, we will set up per our original method and guide
the reflected beam into the autocollimator. Over 100 ft we estimate we
can align to within 50 to 100 microradians.

The recycling mirror was realigned with the PLX periscope working
around existing optics.

The optical flat for alignment of the beamsplitter was positioned
within the beamtube and monuments placed in preparation for alignment
of the beamsplitter.  Hugh Radkins will be completing the alignment of
the beamsplitter.

Myron will be traveling to Hanford on Monday to align the x-arm fold
mirror.  He will be aligning it by guiding the beam to the
autocollimator described above.

ISC/IO Commissioning (Mavalvala, Adhikari, Lawrence, Yoshida, Kells, & others)
-----------------------------------------------------------------------------
The input beam to the mode cleaner was realigned on the PSL/IO table.
The source of the misalignment was found to be a loose steering mirror
mount before the IO EOM train.

The mode cleaner was then locked in air with the beam centered on MC1
and MC3. A visibility of 95% in P-polarization was measured. We then
locked it (for several second stretches only) in the S-polarization and
measured ~80% visibility.

We translated MC2 by 16 mm (based on previous length measurement),
relocked using P-pol ad remeasurd the length. We are now ~0.9 mm too
short (including correction for refractive index of air).

We then replaced the fixed mirror mounts in HAM7 with the DLC mounts
using the 15 m lever to maintain beam pointing. Since then we are
attempting to relock the mode cleaner to get good alignment before we
proceed with alignment of the mode matching telescope and output port
beams. We are having difficulty damping MC1 and have not been able to
lock yet. We are working on that.

In parallel with MC testing, we have been making measurements on the
SOSs to try and devise an algorithm for diagonalizing the input
(sensing) matrices and the output matrices. So far we have had mixed
results but this is still in progress.

--------------------------------------------

Prestabilized Laser -- Peter King
--------------------------------------------

- Construction of two new pre-modecleaners has commenced using the LLO
cleanroom facilities.  So far the two flat mirrors have been epoxied onto
the prism block; the new piezo-transducer/end mirror assembly has been
fabricated and the body block has been epoxied onto the prism.

    Final assembly is expected to be completed sometime today (07/29).

- Debugging the LLO PSL frequency stabilization servo continues.  When the
servo settings are adjusted to lock the 10-W laser to the PSL reference
cavity, non-stationary noise is observed when looking at the error point of
the servo.

    Efforts have been made to track down the source of the
non-stationary noise, suspected to be a parasitic cavity (thanks to Fred
Raab for the explanation and technique on tracking the guilty cavity) in
the frequency stabilization optics train.  The long suspected culprit, the
phase-correcting electro-optic modulator located between the NPRO master
oscillator and the power amplifier, is now unlikely to be the parasitic
cavity since it has now "mis-aligned" and the same behavior is observed.

    As of last night, the frequency stabilization servo is able to
achieve a stable low-bandwidth lock and suppresses noise below approximately
5kHz.  Attempts to increase the bandwidth of the servo, results in the
non-stationary noise appearing.
 

Input/Output Optics -- Dave Reitze, UF
-----------------------------------------

PSL/IOO table

At LHO we checked the PSL/IOO table for the beam misalignment that happend
a couple of weeks ago. We found that the beam was hitting very close to
an edge of the second corner mirror for the EOM chain (two mirrors
upstream from the EOM chain). This caused beam clipping at the third EOM,
and a power loss of 5%. It is not clear why the beam moved. We realigned
the beam. Now the beam is not clipping at the EOM. We checked tha beam
profile after the third EOM by a beam scanner. The measured profile fit to
the Gaussian curve with an error less than 1e-3.

In vacuum optics

The table heights of HAM 7 and HAM 8 have been readjusted. After the
adjustment, HAM 8 table is higher than HAM 7 table by 9.3 mm (before the
adjustment the table height difference was 5.9 mm). The mode cleaner was
locked in the air after this table height adjustment.

On HAM 7, we replaced all the T-mounts with DLC mounts. We used the same
optic for the first steering mirror when we replaced the mount. For the
other mounts, we replaced the optics along with the mount.

We have started to align the IOO in-vacuum optics after the mode cleaner
(MMT1, MMT2, and MMT3).

We tested if SM1, SM2 and MMT1 can be damped by giving a test signal to
each of Position, Pitch and Yaw control path. All the suspended optics
were damped.

LLO installation

A teleconference is scheduled for Fri 7/30 at 8:15 am PT to plan the LLO
IOO installation. The UF group has most of the parts needed for this
already at LLO; the few remaining off-the-shelf items needed will be
ordered this week.
 

Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------

The ETM slated to go to Hanford last week was found during the RTS scan to
have coating defects in the center of the optic.  We have undertaken a
search to find another optic with a near enough radius of curvature.
We have settled on SPETM06, assuming it passes the RTS scan.  The radius of
curvature of 06 lies slightly outside of the ETM matching tolerance band of
+/- 110 meters.  Analysis by Jordan Camp indicates that the 318 meter
mismatch between 03 and 06 will only result in a contrast defect of 0.001.

The tentative plan is to use SPETMs 05 and 01 in one of the 4K IFOs and
(CSIRO) ETMs 01 and 02 in the other 4K IFO.  This is pending RTS scan results.

We have now surveyed all of the ETM radii of curvature.  The results may be
of interest.

Core Optics Coatings -- Helena Armandula
--------------------------------------------------

COC's scatter measurements: We run scatter measurements in two optics:
SPETM04 and SPETM02.
SPETM04 has two coating defects; they look like coating flakes. These are
not an uncommon defect, especially in long coating runs that involve large
substrates. The inside of the coating chamber has moving parts and plenty
of surface area that can potentially shed particles, even if the optic
itself was perfectly clean.
The scatter from these defects is above the LIGO specs.
SPETM02 was also found to have a defect. This defect was noted during
inspection, however, because the defect looked borderline, we made the
decision to make a final evaluation after scatter measurements were taken.
Since we have 5 other spare optics to try to find a match for ETMy already
installed, in order not to compromise the performance of the 2k
interferometer, SPETM02 will also be rejected.

------------------------------------

PO TELESCOPE
Ken M. and Mike S. have pre-aligned on the bench the 2K APS PO telescope.
The IR alignment laser source finally arrived, and the procedure for
acquiring and aligning the telescope with a projected IR pick-off beam was
accomplished in the lab. A few more tests and documentation will be
completed on 7/29, afterwhich the telescope will be disassembled and
shipped to LHO on 7/30. The production contract for 12 more telescopes has
been delayed due to the preoccupation with testing and shipping the first
article this week.

ETM TELESCOPE
The production contract for 6 more ETM telescopes has been delayed due to
the preoccupation with testing and shipping the first article PO telescope
this week.

PO MIRRORS
Steve Bell, Ken M. and Mike S., with help from Betsy W. installed and
rough-aligned on BSC4 the PO mirrors for the ITMx and ITMy. The PO mirror
for the BS was also installed and rough aligned on BSC7. Final alignment
can be verified whenever the COC mirrors are installed and aligned. The
mirror mounts were modified on the spot by placing washers between the
mirror holder and the support frame to provide a bias tilt so that the tilt
adjustment mechanism was centered within the available range. Additional PO
mirrors will be modified with a built-in bias of the support frame.

STEERING MIRRORS
Steve B. assembled 10 sets of steering mirrors, 7 sets were loaned to IOO.
15 sets belonging to IOO are being cleaned and baked at CIT, and 7 of those
will be traded for the borrowed ones.

CAVITY BEAM DUMP
Several improperly made beam dump parts are being reworked by the
manufacture. Shipment to LHO is expected by 8/2.

VACUUM WINDOW
Jonathan is assembling the vac windows for HAM9, HAM10, and BSC6.

COS IR ALIGNMENT BEAM
The IR laser diode was received and tested okay.

ARM CAVITY BAFFLE
Paul K. has completed the detailing the the inner frame assembly (surfboard
glass-mounting structure). Drawings have been sent to 5 prospective
vendors, and we are awaiting quotes. He is detailing the external frame and
the glass plates.

CONICAL BAFFLE
A purchase order for all 6 baffles was let.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack :
Hytec has completed the Mobil Rack for LHO. This rack is undergoing the
hardware and software checkout of the equipment.  The junction-boxes are
being prepared for machining. Hytec has begun the assembly of rack #4.
This rack will include multiplexing for the two remaining vertex BSC's at
LHO. The side panel strongback and the pneumatics box have been finished.
Wiring the side panel will begin early next week and is expected to be
installed in the rack by the end of next week.

2. Fine X-Stage:
The final 20 assemblies are currently being manufactured by Hand Precision.
They are expected to be completed thid Friday. Four units will ship to LHO
tomorrow via Fed Ex over nite, and the final 16 are shipping tomorrow to
the sites (8 ea) via common carrier.

Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Janeen:
-Working on LLO suspension preparation work. Helena and I will
visit LLO for the week of August 23rd with the goal of suspending
the MMT3.
-Tentatively, Mark will visit LHO the week of August 9th. Hopefully,
there will be a suitable ETMx up there at that time that he will
suspend. ETMy is wrapped in foil waiting for installation. He will
double-check the balance of the ITMx and support installation of
the ITMx and FMx.
-Working on little beam dumps for in-vacuum installation for stray
alignment beams. We will use Mike Smith's broken black glass for
these. It will be cut to size and broadband AR coated.

---------------------------------------------------------

Global Diagnostics System
(Daniel Sigg, John Zweizig)

The DMT Sun E-450 machine is now operational and has the
DMT software installed and is running smoothly. The DMT
machine is a member of the CDS, GC and LDAS networks
via an ATM OC-12 connection to the LDAS switch. Once
the dedicated GDS frame builder hardware (Sun Ultra-10)
has been delivered, a point-to-point GigaBit Ethernet link to
the new frame builder will be added.

A new root macro (Chart.cc) has been written to generate
band-limited-RMS strip charts for arbitrary channels and
arbitrary frequency bands. This macro reads in a configuration
file defining the Channels and Bands, and can optionally write
the chart points to an ascii file for later analysis.

The gigabit ethernet hub and the gds frame builder hardware is
delayed. Expected installation date: mid September.

Tentatively agreed with Rolf to equip mid/end stations with 4M
reflective memory modules so that their DCUs can read the
test points and output them to a digital-to-analog converter
if needed.

Agreed to add ADC gain settings to the NDS interface so that
data viewer and diagnostics test tool can display physical
units (rather than ADC numbers).

Fixed a bug in the excitation engine which confused the
DAQ system controller.

1.4.3 Systems Engineering / Data Analysis and Computing

Modeling

[Matt Evans] [Hiro Yamamoto]
o     Worked on the field operation formalizm in the Adlib.

o     Worked with Beng about the choice of Matrix class to be adopted in e2e.

[Biplab Bhawal] [Rick Savage]
o     Biplab and Rick worked together at LHO on the PSL model.

o     Extra measurements are done to validate the model.

o     The source files and data files are organizsed so that the comparison
        at later time will be easier.

[ Sergei Klimenko]
o    Sergei completed the implementation of servo loops for the frequency
      stabilization and MC length control.

o    Will start on the implementation of the alignment controil.

o    The intergation with PSL is ascheduled at LHO at the end of August
       with Rick and Hiro.

[ Conrad Taylor]
o       completed the integration of the STL into AdlibMM, ALParser,
        and AnsiSup packages.

o       worked with Suresh in getting the correct pacthes installed
        for the Sun C++ 5.0 compiler.

o       resolved the bug which caused the executable, 'modeler', to
        hang in the g++ build of the e2e source.

o       optimized additional source code where it was appropriate.

o       profiled the AdlibMM package using 'gprof' and noticed a
        significant increase in performance.

o      The speed improvement of factor of 3 was achieved by the
        transition to STL and optimization.

[SURF]
o      Michelle studied the behavior of triangular model clener.
o      Sam worked on the comparison of the full LIGO optics system with the
        worked done last year at LHO.

LDAS software

[Masha Barnes]
* (MB) - Added I/O function to the lightweightAPI;

* (MB) - Finished conversion function for lwAPI from ILWD to XML;

* (MB) - Working on adding C++ code to the swig wrappers.

[Kent Blackburn]

* (JKB) The LDAS software group is working at Hanford this week to
        install an alpha release of the LDAS software on the computer
        on the LDAS subnet. Much has been learned by all while we
        work on in an environment with identical software tools to
        our CIT environment but drastically different topology. The
        team has made wonderful strides towards our goals. Several
        troublesome issues have developed which we will work to
        correct, both here and at CIT:
        - discovered that Solaris 7 has changed socklen_t as to cause
          binary incompatibility with older code. LDAS uses socklen_t
          so we will have to upgrade our CIT computers immediately.
        - frames have been coming out of the framebuilder at rates
          from 3 to 7 frames per second. This is being worked by CDS
          but in the meantime we are making our code smarter to these
          sorts of odd behaviors.
        - The size of the LDAS APIs were about 8 times larger than
          earlier reports due to a confusion in the SZ field of ps.
          We are working to downsize these APIs.

* (JKB) The 18GB hard disk for the controlmon linux workstation arrived
        and after making an IDE cable and digging up some mounting hard
        ware it was installed. We have now identified a small problem
        with different versions of NFS (2 vs 3) between Solaris 7 and
        Redhat Linux 6. A release of NFS3 for linux will be out soon
        which will remove the need for some minor modifications that we
        are implementing to allow NFS communications.
[ Phil Ehrens ]
* (PSE) This week I was at Hanford with Albert, Kent, Dave, Masha,
        Ed, and Xhao to install the LDAS software on the ligo-wa/
        ldas-wa network.

* (PSE) Installed the manager API and the frame API on the LDAS
        dataserver (ldas.ligo-wa.caltech.edu/dataserver.ldas-wa)
        in Hanford.  They are currently running as user 'ldas',
        with the manager on ports 10001-10003, the frame API on
        ports 10004-10006.  Port assignments are, respectively,
        "operator", "emergency", and "data".  The "data" port is
        not used at this time.

* (PSE) Updated the CVS source to reflect all modifications made
        during the install at hanford.
 

[David Farnham]
* (DWF) fixed some problems with the Make scripts for the LDAS alpha
        distribution.

* (DWF) fixed a bug in the FrameCPP which caused it to return NULL when
        reading a frame.

* (DWF) set-up the LDAS production and development directory hierarchy on
        Spica (to be mirrored to the sites).

* (DWF) Installed the LDAS distribution on Spica and at Hanford.

* (DWF) Continued working on the Lightweight API with Masha.

[Xiao Hu]
* XHU worked on db2 performance test on disk cache

* XHU worked on gds/ilwd program

* XHU worked on metadataAPI

[Barbara Kratochwill]
* (BK) Installed DB2 client software on my pc, created and loaded the
       CDS database on deneb, updated all the web forms with the new
       userid and password, and retested.  Installed DB2 client software
       and moved the forms to the internal WebBase NT server.

[Mary Lei]
* (ML)  Changed metadataAPI at CIT to conform to installation
        environment. Committed changes.

* (ML)  Test descMetaData at CIT : unit test and via manager.

* (ML)  Set up metadataAPI to run on metaserver on Hanford.

[Edward Maros]
* (EFM) Cleaned up cfengine scripts for Hanford site.

* (EFM) Worked on trying to get mail out of private network.
 

LDAS Hardware

>From Ed Maros,
* (EFM) Formatted the new 18GB HD for controlmon

>From Stuart Anderson,
        I have finished the performance evaluation of the Network Appliance
network attached file server. The web page of the results may be found at:

http://www.srl.caltech.edu/personnel/sba/ligo/raid/netapp.html

for comparison, see also the review of a cheaper host attached SCSI solution
from Cybernetics at:

http://www.srl.caltech.edu/personnel/sba/ligo/raid/cybernetics.html

        I have also done further research into a possible LIGO IBM SUR grant
for $1M in hardware for the main LIGO archive.

Computing

MIT:
Nothing to report.

Hanford:

A new Sun 450 computer has been setup.  This computer is intended to be
used for all CPU intensive data analysis done through the GC network.
This will take the load off the server and help cut down on user caused
server crashes.

Jill's NT computer now has limited network access.  Turns out there may
be a compatibility problem between the NT OS and SAMBA, the UNIX/Windows
network server software.  Larry Wallace has a fix for me to try.

With all the visitors here this week, I have spent time helping visitors
find places to connect laptops, find places where they can sit and work,
added several new user accounts and dealt with problems from users
overloading the server.  I have helped with questions about LDAS
connection to GC printers and etc. and attended a meeting on LDAS, CDS,
GDS, and GC application software compatibility.

Larry Wallace was able to get a modem connection working from his
computer at Caltech to our modem, however, I haven't been able to
reproduce that here.  Spent several hours testing with Richard
McCarthy's and Rick Savage's help, trying to find out if the problem was
with the phone system or the modem or the modem router.  It appears
there are problems with all the systems.  It can take several tries to
get the modem to answer because of the phone system switching between
lines. Once the modem does answer there are problems logging in to the
server and problems trying to run email and web software.  More testing
is needed to pinpoint the fixes.

Lazzarini: Kent and I visited with PNNL's Networking Administrator John McCoy
in order to discuss status of PNNL's OC3[ATM] connection to Seattle's
gigpop node. Work is behind planned progress but should still be in place by 1 Oct.
I have initiated discussions with PNNL on getting from them a quote for
cost of service for expanding our service beyond the present T1 connection.
In addition, our technical point of contact has finally provided me with network
usage statistical data. I have analyzed this and the summary information
may be seen visually in the following charts [caution: they are ~ 1MB each]:

http://www.ligo.caltech.edu/~lazz/distribution/LigoPerf_Jun99.pdf

http://www.ligo.caltech.edu/~lazz/distribution/LigoPerf_Jan99.pdf

Data from each day of the month are overlaid.
These may be summarized as follows:

Jan peak usages:        FROM LHO:   58 kB/s (peaks @ 0800=> email access?)
                                      TO LHO:         77 kB/s

Volume transferred: FROM LHO:  > 768 GB (peak 0800=> email access?)
                                       TO LHO:         > 663 GB

Only limits available due to the fact that only RMS quantities were provided.

Jun peak usages:      FROM LHO:   74 kB/s (occurred only once; LHO has own mailer server now)
                                    TO LHO:         104 kB/s
 

Volume transferred:     FROM LHO:  507 GB
                                           TO LHO:       2.4  TB

Livingston:

We are in the process of upgrading to Solaris 7, and are also upgrading
some third-party software at the same time.
We have placed an order for an 18 Gb disk for user files.

CIT:
Barbara Installed version 5 of the DCC entry application into production. It has
Y2K changes plus utilities for maintaining the lookup tables and doing a
specialized keyword query.
Made some changes to PubDocs based on testing.  Production installation
is awaiting some changes to the Publications category.

Samantha has been busy repairing PC's and reloading the OS on them. Once again
one of the Microns needed another part replacement. The mother board on one of
the Gateways went out and is being replaced. The problem of installing and
designating a specific drive name to the ZIP drive on one of the web server has
been resolved, a zip disk needs to be in the drive during the installation
procedure in order for everything to work correctly. There have been a number of
upgrades on the PC's which should be 95% complete.
Sam will get back to checking for Y2K problems next week.

Suresh worked on last Saturday's power outage, a number of Sun systems, PCs,
printers etc. except servers were shutdown and brought back to online state
later
in the afternoon on same day. However, all Ligo buildings except 40-meter lab
were not affected by this outages, we did it for preventive sake.
Two Suns systems in 40-meter lab (suhail and zaurak) were rebuilt from
scratch after noticing they were not functioning properly.
Monthly full backups of servers have begun.
Working on removal of old user accounts from sirius. The accounts will be put to
both tape and CD before being removed from the system. A list of accounts to be
removed is being generated for approval.
Assisted users for retrieving lost files from archives, resolved file, mail,
web related problems.

There has been a great deal of time spent on trying to get things working for
the new Oracle system. A number of tests dealing with accounts, the network and
VPN have been performed. Some of the issues appear to be hardware related and
others we are still trying to get a handle on.
The new cisco router is in place for connection to the CITNet2000. As soon as
the ITS people get a chance they will complete the procedures for the
connection.
The portable air conditioner being used in the computer room has made it
possible
to start/continue installing and testing the new equipment. The new air
conditioner for the computer room is to be installed in two-three weeks. Until
then the air that we have should keep things cool enough to where we won't lose
anymore equipment.

Cadence has been installed and Lori R. has tested it out on sadal. She is now
testing it on other machines. When the main users return I am sure they will be
testing out the new installation since the licenses expire this week on the old
pkg..
A number of groups on campus are wanting to use the Cadence s/w, including the
biology department. We are setting it up to where they load the s/w on one of
their systems and just get the licenses from us. We already have too many
machines across campus mounting the cadence server.

Working a number of procurement issues.
 


WBS 1.4.4.1    Administrative Group


Dorothy Lloyd

Spent a lot of time working (re-learning) Oracle when using the base applications for inputting requisitions. Of course, this was accomplished with both Sherri Weed and Susan Dollar from ACS at my side.

Continued to process as many invoices for payment as the new system will allow. However, many contract and blanket/open order invoices that have multiple account distributions are on hold due to a problem that occurred when they were converted from IFIS to Oracle. For this, I produced a list of 30 or so blanket/open orders to Acquisitions to re-enter in Oracle in the correct format for payments to be made.

Tracked and followed up on various invoice problems, and signed off and closed out a number of PO receivers.

Continued to monitor and support the temp.

Rita Torres

Attended 2 Hr. meeting with representatives of Finance, and Oracle system, to discuss access and the procedure for doing subcontracts. Earlier in the week prepared for P. Burton a list of LIGO subcontracts to facilitate the "Purchase Contract Header" for each document in order to facilitate purchasing actions in Oracle. Spent 1-1/2 Hrs. with S. Weed and D. Lloyd discussing requisitions and practicing their input.

For I. Petrac helped format and number two Attachments to MOU for University of Wisconsin-Milwaukee. Also did letter to A. Sergeev to transmit MOU Attachments; sent Registered in order to obtain his signature for receipt. For S. Meshkov began creating documents for Visitor Program of 2000-2003, the Summary came out to 13 pages; work ongoing.

For E. Jasnow did letter to MMR to transmit contract #1000084 for signature, this is for BT Bakeout at LLO. For D. Coyne did letter to WA, DC which was faxed then mailed.

Irene Baldon

I was on vacation last week and this week has been consumed with catching up, sorting out, figuring out what I have and don't have, attending and Oracle Mtg., etc. Better report next week.

Elizabeth K. Wood

In trying to make up for missing all the ORACLE training classes at the end of June, I have been observing Dot and Gary work with the new system and taking copious notes in the process.

On Tuesday, the administrative staff attended a rather lengthy meeting with Sherri Weed, Susan Dollar, Tina Lowenthal, and an ORACLE guru to discuss concerns and the future of LIGO's implementation of the ORACLE financial system. The hope is to get the bugs worked out while using LIGO as a test case for the rest of campus. As one person sagely pointed out, weren't the bugs worked out before ORACLE went live? On the other hand, LIGO gets to try everything first. Note that I did not say the good news is that LIGO gets to try everything first.

As promised, construction has begun in room 358 WB for the installation of a new CITNET 2000 closet. Once the carpenters are done, the stringers of wire will do their thing. Don’t say I didn’t warn you.

Remember back in April when I said that yes, you need to use subaccount numbers, but no, we won't tell you what they are?  Now that no one needs the old-style subaccount numbers, they are all posted on the web, completely available to everyone.

Dealt with personnel issues, payroll, visas, missing paychecks . . .
