The Project Control Meeting
Agenda for Monday May 4, 1998 will be:
(Meeting time: 10:30 am Pacific Time)
WBS 1.1.1 Vacuum Equipment(Worden)
1. Gate Valves:
In preparation for the first LVEA bake, PSI has
bagged three
valves connected to the left beam manifold and found
no
more problems here.
PSI is waiting for a written report/plan to deal
with the leaky
bellows.
2. One bake oven load remains to be processed to
complete the
MIT chambers.
3. All LA chambers have shipped. Only GNB valves
remain
to be shipped.
4. Installation activities:(Kyle Ryan)
X-arm end station:
GNB determined that the 44" VE gate valve
leak was the result of a damaged lead screw
bellows. They have one on order.
X-arm mid station:
PSI inspected the interior of the 2500 L/s ion
pump and found that the gap between one of the
two high voltage bus bars and ground was too
tight (only one of the two pumps which comprise
the "2500 L/s ion pump" had been functional).
They increased this gap and it appears to have
fixed the problem.
Corner Station:
PSI replaced the vent line bellows on the left
80K pump (long). No welding was performed.
The
local roots pump PSI was utilizing to rough the
left BT manifold exhausted oil. Only one pipe
section of the header was effected. It was
clean-
ed and the pump will be repaired. The left
BT
manifold is now pumped down and leak checked.
Most of the bake blankets have been installed.
Y-arm mid station:
PSI is preparing for the "100 hour back to air"
commissioning.
Y-arm end station:
PSI modified the 80K pump level control valve by
changing the needle and seat sizes.
Livingston Status (Allen Sibley)
1) Rec'd the req from Ed Jasnow for LN2 for LA. Bids are due in 5/11.
PSI
requires LN2 on 6/8. This will be very close and I will continue to
monitor.
2) Cleaning of the LVEA floor has been completed and Dave Evers has
accepted the responsibility for maintaing the area.
3) The overhead door in the Rt. end is still broken. No one seems to
know
what happened to it. If this is not resolved by soon we will be impacting
PSI. The part that is needed is here according to H-P but no one is
here
working on it. I will contact H-P to get this moving. It will take
a day to
install and we may have a problem with PSI's access to the VEA
to install
the BSC. PSI is ready to move it into VEA and may claim that their
installation schedule is being impacted.
4) I have informed Dave Evers that LIGO will clean the area outside
the
cleaning area with brooms only and that that will be the end of LIGO
responsibility for keeping the area clean.
5) We had several meetings with SJB regarding the survey of the LVEA
and
arm-1 end station. We think we now have closure and have a meeting
scheduled with Albert and Larry to finalize the results.

Turbopumping the X arm continues,
with minor problems
causing pump shutdowns.
CBI has been requested to take a
wipe sample to check for
oil contamination each time a
vacuum pump line has been
disconnected, following the
recent discovery of oil
in a Roots roughing pump exhaust
line at Hanford.
CBI has started coring the
holes in the concrete enclosures
for direct GPS access on
the beam tube supports. Of 34
needed on the X arm, 16
have been cored to date.
CBI has issued a request
for direction regarding SJB's move
of the interface mark on
BT/VE1 and CBI's questioning of
the BT/VE4 mark. A meeting
will be held on 4/30 to discuss
SJB performance and our
response to CBI's request.

DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
-----------------------------------------------
Implementation Group -- Mark Coles/Fred Raab
-----------------------------------------------
40m (Jennifer Logan)
--------------------
Last weekend's earthquake has misaligned the East End mass to an extent
where we have to vent in order to realign it. This vent is planned
for
the end of the week to allow Bil to finish some wavefront sensor
working that is being done on the simple Michelson.
As a first step, the differential mode in yaw of the Simple Michelson
has been controlled by the wave front sensors. Today we hope
to
implement control of both pitch and yaw. Walid is now starting
work on
software for the wavefront sensing which will be a great help in
implementing the system.
As part of testing one of the wavefront sensor heads it became evident
that we were seeing fringes at the symmetric port despite the fact
that
the only interferometer component aligned at the time was the recycling
mirror. We tested components outside the vacuum system and failed
to
find a culprit for the parasitic interferometer and so when we vent
this week we shall take the opportunity to look inside the system for
the cause.
Dick has been continuing his work on designing and testing an aluminum
substrate for the Pockel cells and I have been looking at the Lithium
Niobate cell that was sent to us by New Focus for testing. However
given
that work at the 40m at 514nm will be scaling back towards the end
of the
year and that our current cell shows no signs of degrading so far and
we have spares, we will be scaling back this effort.
----------------------------------------------
Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Initial alignment (Zucker, Mason)
------------------------------------
Completed IAS final design review 4/30. The most significant
actions
concerned coordination and time phasing of the suspension installation
among SUS, COS and ISC tasks, and trying as much of it as possible
in
advance to get the dance steps down. Very few actions concerned
the
IAS equipment design. We have received preliminary approval to
proceed
with procurement and fabrication. Thanks to the committee and
observers for many helpful comments.
LSC lock acquisition (Ware)
------------------------------
Learned more about the original design of SMAC and controllers, in
the
process of studying discrepancies between Bode plots and SMAC results.
Implemented a State indicator in SMAC which delineates what state the
system is in at a given time. Started to look at deriving phase
information from SMAC variables (not done in original model!).
Met
with Dave Redding to discuss completion of documentation of SMAC
modeling. Discussed various details with Lisa.
In other words, another step up on the learning curve this week.
ISC Design/Testing (Mavalvala)
--------------------------------
LSC Detection Mode Controls:
The LSC common-mode design is complete enough that documentation
is underway. Small design tweaks are still in the works as the
anti-aliasing filter and test mass resonance notch filter designs
are developed and tested by Dale O.
We tested some time-domain simulations on the common-mode servo
model in collaboration with Gabriela G. at PSU. Except for the
very simplest stripped down loop, the integrations failed to
converge, again attributable to numerical instabilities.
ASC Controls:
With Gabriela G. we revisited the wavefront sensor control model
to determine the status of the ASC controls design and update the
models for the Final Design.
LSC Photodetectors (Zucker for Csatorday)
-----------------------------------------
The first production LSC main photodetector module is now
undergoing linearity and response tests in the optics lab.
Looking good, Dale!
LSC digital loop test @ PNI (Fritschel, Daw)
--------------------------------------------
o Ed D discovered that the glitches seen in the output of the Pentek
DAC were due to timing errors in the system; he tracked this down
further to an intermittent increase in the time taken by the
Baja
processor to respond to the Pentek's ADC interrupt. This in turn was
caused by a network process running on the Baja that seemed to have
a
too high a priority. Suspending this network process resulted in
glitch-free operation. The problem now is to figure out how to keep
the
network task running (so we can communicate with the processor), but
at
a low enough priority so that it doesn't interfere with the Pentek
interrupts.
o We also working on the code to implement the servo filtering
functions for the Michelson loop, and learning lots of fun stuff about
digital filters in the process.
-------------------------------------------
Lasers and Optics -- J. Camp
(1.2.1.1.2, 1.2.1.1.3, 1.2.1.1.4,1.2.1.1.5)
--------------------------------------------
10 W Laser Contract -- Jordan Camp
------------------------------------
Nothing to report.
Prestabilized Laser -- Peter King
--------------------------------------------
- R. Abbott has been working on the VMEbus intensity stabilization servo,
as the previous version of the card did not provide enough gain to
suppress
the intensity noise to the required level.
Each stage of the salvaged card has been tested and
more or less
behaves as predicted. However when used to suppress the intensity
noise,
there is still not enough gain beyond ~1 kHz. At frequencies
greater than
~7 kHz and less than 12 kHz, noise is added to the system. With
what would
appear to be ample phase margin (greater than 40 degrees and as high
as 60
degrees), the behaviour of the servo is not understood at present.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
IOO construction
We are still collecting quotes/orders for the IOO commercial parts.
Quotes have been requested from about 10 vendors for such things as
posts, mirror mounts, fork clamps, lens-holders, dog clamps, etc.
Mode-matching Measurement
Rana made measurments of capacitance of the bullseye photodiode -
good uniformity from segment to segment. Installed DAQ board with
software + LABView 4.0. Acquired connectors, cables, etc. Modified
Head
Board box in the machine shop. Am beginning DSP programming today.
High Power Testing
We measured the stray B-field of a Faraday rotator of 12 mm clear aperture
manufactured by EOT (Electro-optics Technology). Previously
we had
measured 8 mm. The measured B-field does not show substantial difference
from the case of the 8 mm clear
aperture Faraday rotator (manufactured by EOT) that we measured
previously. The maximum difference was observed at z~25 cm r<5 cm,
where z
is the coordinate along the optical path and r is perpendicular to
it. At
this location the B-field measured for the 12 mm aperture Faraday rotator
is higher than that of the 8 mm aperture Faraday rotator by ~25%. This
B-field is, however, still lower than the B-field level that we have
estimated to cause SOS displacement that is two to five orders of
magnitude lower than the open loop SOS displacement. Thus it can be
concluded that the 12 mm aperture Faraday rotator can be employed in
the
2K and 4K LIGO.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
The first group of 5 substrates arrived at REO for coating, 9 more follow
this week. The Contract for coating of the 40 LIGO optics has
been
approved by NSF. We expect the first delivery May 15th.
Brian Loucks is working again (after a brief hiatus while we switched
IR
interferometer vendors) on tooling to support the interferometer and
optic
under test. Since the new configuration is very similar to the
one at
NIST, delivery times are anticipated to be short.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE:
D. Rose has completed the tolerance requirements for the 1) parabolic
PO
telescope mirrors
and 2)refractive ETM PO telescope. Requests for final quotes have been
sent
out for both sets of telescope elements.
K. Mailand is finalizing the details of the parabolic PO telescope
mirror
mounts, housing, and support structures.
BEAM-DUMPS:
A. Badalian is working on the design of the beam-dumps.
COS PARTS LIST:
M. Smith has created a preliminary data base using a systematic naming
convention to describe top assembly, subassembly, and component for
the COS
parts. The list can be sorted by category to obtain information about
field
replaceable items, repairable subassemblies, and stocked items. The
list
can be totalled to determine the total number of individual components
which must be ordered. The list provided data to track the order date,
received date, assembly date, and ship-to-site date.

Isolation Group (Mike Fine)
---------------------------
Seismic Design (Mike Fine)
--------------------------------------
1. Assembly Hardware:
Hytec has completed all the alignment of the prototype BSC up to the
pier
adapter
plates. The procedure that was developed earlier has been proven workable.
Hyec is
making the necessary changes to the procedure, and will then adapt
the BSC
process
to the HAM. Phase II hardware will ship to Hanford this week. We are
expecting the
>hardware to arrive at Hanford today. The order for the additional
HAM rail
assemblies with Vertex has been placed. Orders for the Phase III assembly
hardware
for the HAM have been placed. In order to expedite the fabrication,
the
orderd are
broken up such taht the bellows clamp will be fabricated by Jona in
Los
Alamos, and
the remainder of the hardware, by Noor Mfg in Albuquerque. Delivery
times
are 3-4
weeks for this hardware.
2. Coarse Actuator Component Testing:
The test fixturing for the actuator components have arrived at Hytec
and is
being
configured. Hytec anticipates to test the flexure stage for the XY
actuator
system
next week. The dummy Z stages and X/Y stages are being fit-checked
at Hytec
this week
and, if all goes well, will be shipped to Hanford next week.
3. Air Bearing Assembly:
The prototype air bearing was tested earlier this week at Specialty
Component. The test
of both flate and spherical bearings was conducted under 3500 lb (BSC
load); with 150
psi air supply, the air gap of ~.0002" was achieved without any evidence
of
vibration.
The flow meter was not avaialable to measure the air flow but SC will
obtain a meter
and measure the flow next week. They will also test the frictional
coefficient of
the surfaces.
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. LOS Fabrication:
Bill Tyler and Mike F visited Brookfield this Tuesday. Brookfield has
completed the 1st article height adapter and are awaiting the rest
of the
info on the compound angle definitions to complete the final machining
of the
1st article welded structure. For the production lot, they have all
the
components
machined and weld-prepped, ready to be sent to welder for assembly
soon as
they
receive go-ahead from us.
2. LOS Fixtures:
We have received shipment of the clamps, dumbell standoffs, side standoffs
and guide rods from Schober's. More shipments are coming.

Global Diagnostics System
(Rolf Bork, Paul Govereau, Mark Pratt, David Shoemaker, Daniel Sigg)
--------------------------------------------------------------------
Software development for GDS continues this week. MP continues
work
on the excitation system, DS on the scheduler and PG on c++ compiling
under vxWorks. Recent developments include installation of the
GDS
heartbeat on the PNI reflected memory network.
Received a new Baja4700E at LHO. After solving several installation
hassles related to driver version conflicts it is finally up an running.
Had a meeting with CDS and LDAS to discuss LIGO time representation
and distribution. In short: time will be expressed as seconds
starting Sunday, Jan. 6, 1980, 00:00:00UTC (GPS zero). However,
any time format of type month/day etc. will be strictly UTC to avoid
misinterpretation (for instance the IRIG-B signals).
Physics Environment Monitor (Alex Marin)
-------------------------------------------
We received almost all the parts of the DAQ and PC for the PEM cart
to be
used for the 1st SEI article test. We are working on the assembly of
the
hardware and then we will start to write some software for the NI-DAQ
system, which will have up to 8 channels with setable gains, which
can
acquire (new) simmultaneously data at minimum 10kHz (depends on the
number of channels used).
Optical Contamination (Daqun Li)
---------------------
Continued to take ringdown and mode spacing data from two cavities;
Continued to bakeout the third contamination cavity (inner chamber and
spacier)
and gather components for setting up the third cavity;
Non-Optical Contamination (Matt Smith)
--------------------------------------
Matt is traveling to Hanford to start setting up for the SEI vacuum testing.

OFF CAMPUS OVERHEAD RATES (Lindquist)
Federal Accounting has established special "fund" accounts for Hanford
and Livingston Operations charges that will force the application of
the
off-campus overhead rate starting October 1, 1997 for the sites.
To do
this we will be switching account numbers as described in the following
message from Barbara Comfort:
The new 5PXXX accounts, set-up to allow the off-campus overhead
rate
of 21.5% to be charged, have all been activated as of today (April
29,
1998). Please inform your people of the new numbers and have
them make
the necessary purchase order and payroll changes. Listed below

bakeout in Hanford. The selected contractor was Sun River Electric
of
Kennewick, WA. This will be a time and materials contract for
$400,000. It
is expected that the approval package for this contract will be sent
to the
NSF early next week, with discussions held during the teleconference
scheduled for May 12.
Discussions continue with Hensel Phelps concerning the issue of additional
costs for cleaning of ducts in the LVEA. Hensel Phelps has submitted
a
proposal for settlement of this issue, which is being reviewed.
Specifications for the new building at Hanford have been received, and
an
invitation for bid is being prepared.
TECHNICAL CONFIGURATION MANAGEMENT (Althouse)
Nothing special to report this week.
1.4.2.1 Quality Assurance (Tyler)
From: "William H. Tyler" <tyler_w@ligo.caltech.edu>
LIGO QA (R. Vincent) witnessed 20 open/close cycle gate valve test at
GNB.
Mr. Vincent also witnessed a final leak test of another gate valve.
Both
test activities were completed successfully. Early this week, Mr. Vincent
was advised by GNB that they were suspending work on the remaining
gate
valves while they investigated an actuator bellows leak problem which
appeared to be due to a design error. John Worden has provided a more
detailed description of this problem and the potential impacts to LIGO
to
modify/rework the GNB gate valves in a separate e-mail message.
LIGO QA accompanied M. Fine to visit the air bearing vendor to observe
tests of a prototype under load and to survey this vendor's QA
methods/processes. Although a small two person operation, this vendor's
products are produced with a lot of attention to workmanship "quality"
and
delivering a "quality product". I would rate this vendor as "approved"
for
LIGO fabrication. Their major weakness is the fact that they are only
a two
man shop (limited "redundancy" or "backup" expert workforce). Other
vendors
visited on this trip were Pegasus Manufacturing (internal damped coil
springs, KTI (coil spring EB welded end caps) and Brookfield Machine
(support structures).
1.4.3 Systems Engineering
1.4.3.1 Systems Engineering & Integration (AL, BB, CC, JK, DC)
__Integration Planning:
Cable Tray Specification
Bill Baldwin has written a draft specification for the cable tray
installation in the LHO Corner Station and put it out for review at
this week's integration meeting. Once the general approach and
the
requirements have been agreed on then the specification will be
extended to the Mid and End stations and a bid package will be put
together.
__Analyses:
Lazzarini is working on a refined Mathematica model to track LIGO
outgassing estimates.
Lazzarini has met several times with facilities folks to
resolve/understand alignment issues at Livingston. Latest
teleconference appears to have put the issues to bed: the site
alignment will be within required bounds (i.e., 90deg. arms; 46.00
m
distances to corner station interfaces); only remaining issue is a
4 mm
discrepancy (transverse) between location of the BT/VE interface forthe
Y arm End station (BT/VE4). We can live with either the SJB location
or
the CBI location.
__Reliability:
Feedback was received from S. Whitcomb on the initial draft of the COC
section of the LIGO Maintenance Plan. PEM MP section is still under
review. DAQ MP section was given to R. Bork for review.
J. Worden was contacted with regards to VE maintenance issues. J.
Worden said that a review is taking place in mid-May with the
contractor in which documentation would be provided addressing these
issues. The VE MP section will be outlined with the details filled
in
after the mid-May review.
__Integrated Layout/Drawings:
CDI DRAWING RELEASE
Drawings have been upgraded to A change revision
for Initial
Release. Drawings will be sent to DCC starting
Monday, 5/4/98,
and complete by Friday, 5/8/98.
MIT LEVER LAYOUT
This project is now on temporary hold due to the
possible
change to the Louvre Baffles in spools numbers BE-5
& BE-6. No
date of completion is projected.
WASHINGTON OPTOMECHANICAL ILDs
The Mid Station xref's are set up waiting for input
from the
various groups (IOO, ISC,COS). When time permits,
will also set
up End Stations.
PSL/IOO XREF LAYOUTS FOR ILDs
This is not started yet due to current priorities.
Will start
assembling the Optical Enclosure (PSL/IOO table)
package near
the first or middle of next month, (May), and hopefully receive input
on the PSL and the IOO layouts.
Worked with MIT on the new PEM Sensor layer for the Washington Corner
Equipment Arrangement Integrated Layout Drawing (D970310). A new
version of D970310 will be filed by Tuesday 5/5.
Continued work on LOS2 Large Optic Suspension production drawings.
Currently working on the structural weldment.
Assisted with modal analysis for the PSL Pre Mode Cleaner.
__Mock-ups:
HAM LOWER HALF MOCK UP
The Ham half mock up arrived in Hanford, on Wednesday 4/29/98.
ELEVATED PLATFORM MOCK UPS
Have received a couple of replies & am expecting
additional
product information from a few companies on platforms
with
larger work surfaces then the one unit that we purchased. Other
projects have been injected ahead of this project but, will try to
make
a decision on purchase plan by Wednesday of next week (5/6/98).
HAM 84" ACCESS & 14" ("E") NOZZLE GUARDS W/COVERS
Have finished the drawings except for a few dimensions
which
Larry Jones supplied, this week. Will try to finish
the
drawings by next Tuesday, 5/5/98. month.
1.4.3.3 Modeling & Data Analysis (KB/HY/AL)
TEMxx Modal Implementation :
Generic and smart version (a.la.A266) of the mode decompostion matrix
for the rotation and displacement have been implemented. Formulation
of
tracing the base of the mode base, characterized by waste size and
focal point, has been done.
Garching workshop :
Hiro atteneded the Garching workshop "LSC Workshop on Software Tools
for AIC". Attendees were from LIGO, GEO, TAMA and ACIGA. Unfortunately,
no one attened from VIRGO (no reply to invitation mails from the GEO
organizer). Each group explained ( including demonstrations by
some )
their software tools, discussed the future directions of tools,
including
* Standarlization
* Validations
* Physics
* Shared efforts
* Development of time domain models
At the workshop, Twiddle and End to End model were demo-ed and received
good attention of people. GEO group has twiddle-like software,
originally written by Jun Mizuno, and these softwares were compared
for
the Dual Recycling configuration transfer function, and agreed well.
A webpage will be prepared which lists all the simulation tools
available.
Alfi :
Robust memory handling is implemented to make Alfi more stable.
Data Analysis and Modeling:
KB met with Bruce Sears to discuss security policies as they apply to
TCL/TK plug-ins (tclets). Bruce has agreed to look into what it means
to modify default security policies and to generate new security
policies associated with tclets as they are planned for LIGO's data
analysis.
KB attended the LSC ASIS sub-group meeting that was held this week to
finish up discussions of the priorities in each of the coordinators'
categories. KB reported on priorities associated with Noise Models
to
be used by the group in proto-typing and developing data analysis
algorithms. The highest priority is to get an acceptance/approval for
the estimated noise curves generated using parameters taken from
sub-system review docs and make these curves available for the LSC
community through a webpage. These curves are currently being generated
using the C++ Noise Class Library developed last summer by KB's SURF
project. KB has updated parameters in these models to reflect David
Shoemaker's current thinking of the performance of the suspension.
KB
also needs to update some of the models to these classes(seismic
angular excitations and gravity gradient).
KB installed the second alpha release of TCL/TK 8.1 this week to be
able to install a new release of BLT (a collection of high level
widgets for x-y plots, histograms and other useful data display
extensions to TCL/TK. The BLT package works great under this alpha
release of 8.1.
KB downloaded a version of the sockets++ C++ class library this week
and began debugging the code. This was hampered by the poor
configuration of C and C++ compilers on our Sun computer. After making
several modifications of the code, KB was able to compile the source
(but only using gcc from Sirius) and run many of the test programs.
For
the most part the socket classes seem to be working on the SUNs.
However, KB also worked to port the code to LINUX this week. The code
was modified and bugs fixed so that the same code builds on both Sirius
and Linux, but the test programs on the Linux box are in general not
working. KB is in the process of debugging this code under Linux. Even
though it is not possible to report success with the sockets++ class
library yet, this is a major step forward from the earlier attempts
by
both KB and Walid Majid to work with this package which would not
compile or would core dump on start up.
After waiting a week after receiving the monitor for the new Alpha LDAS
workstation, KB contacted the vendor and then CIT receiving to locate
the CPU unit. It turns out the unit set over in receiving for one week
after Dot told them to contact KB and receiving called the wrong number
and left a message waiting for a reply. The unit should arrive this
week in West Bridge.
Anderson worked on LSC/ASIS related organizational tasks to get the
periodic source search research plan put together.
He also worked on latest ATM problem which looks like it is actually
an
AIX bug not an HPSS bug.
1.4.4.2 General Computing (LW/TE)
Motivated by some of the PAC meeting discussions, Sanders and Lazzarini
subsequently discussed the relative merits of moving LIGO PCs from
Microsoft OS to linux. Gary volunteered to be a "guinea pig" to see
whether this option can support the critically necessary LIGO Lab
general computing functions (i.e., email, web-surfing, calendar
browsing and word processing).
MIT:
1. Preparing for the move to the new building. Trying for a June 22nd
time frame for the move.
2. We had a meeting with the networking people at MIT (April 28th)to
try and get a better setup than the basic offering. Dave S. and Tom
E.
are heading that up. They have been dealing with Steve Goldman.
From
the meeting we are going back to get more information to justify our
needs for a faster network and hope to present that in the near
future.
Hanford:
Nothing to report
Livingston:
1. The PC's have finally arrived and are being installed by
Techmasters. Julian and Allen S. have a map of the addresses for the
machines.
2. Mark Coles has turned in a list of computer names which will be
mapped to IP addresses in the next couple of weeks.
CIT:
1. Multiple computer moves at Bridge. So far no major problems with
the
moves but the multiple little items have taken up time.
2. Finally, we were able to do a full backup on kater. We should be
finished with the full backup of sirius this week. We have three
tape
drives that have gone bad. All three are under warranty and will be
getting sent back with in the week. Two of the drives we will try to
trade-in because of the 2-4 week period before the fixed drives are
returned.
3. Multiple file restorations. I have received a few e-mails from
people saying that they now believe in the importance of backups.
4. We have been working on modifying the DCC setups to allow Linda T.
to have more control over the system.
5. Worked on fixes for netscape and Acrobat. Netscape4 is now on-line
we should have it on the menu in the near future.
6. Multiple accounts added and modified. We are now to a point in-which
most of the CIT users have been moved over to sirius (a few exceptions)
and all we have left are the users not located at CIT. Surresh S. (new
sys. admin.) will be working on those accounts over the next few
months.
7. For the web site: (Barbara K.)
- turned a PDF version of the travel authorization form into
a
web-based form using Adobe Exchange Forms Author. The
form works
like a charm on PCs. We are trying to get the UNIX version to
work.
- developed a transparencies page for PAC4.
- made a variety of changes to the conferences page for Dave
Shoemaker.
8. Barbara K. worked through George Stokes' programs to map out his
logic in assigning a new document number. Began working on a
web-based
form to reserve a new DCC document number.
9. We have had the fibers tested from the basement of Bridge Annex to
the Second floor of Bridge and found that nearly all had bad
connections. The company that installed the fiber will be out to
replace the connections and perform some more tests in the near future.
We will also have the fiber lines that are currently being used by
the
second floor tested after the known bad lines are fixed.

=========================================================
Lab setup:
----------
Delivery of the optic tables for the Optics Lab have been set back
1 week as TMC did not ship per schedule. They shipped out 4/29. LHO
clean room, and clean part handling, storage procedures are being
worked on by R. Savage, K. Ryan and D Cook for the LVEA, Optic Lab
and Vacuum Prep. Areas. Outlines for the laser "Standard Operating
Procedures" For the LVEA and LVA,s are being developed by R.
Savage and D Cook. Added ideas from any of the participating groups
is
always appreciated, especially along the lines of safety interlocks,
enclosures or special needs such as remote operations etc.
Support equipment continues to flow.
HAM First Article Test:
-----------------------
David Hall (contractor) began work on Mon. (4/27).
HAM Pier Centering Jig observed to be a bit flexible; a different method
for locating the HAM Drill Template has been employed and the results
have been within tolerances.
The Redhead Anchor Bolts delivered to the site were too short; a Hilti
Insert/Stud anchoring system will be used instead. Kyle Ryan
will help
with drilling of the holes. The Anchor Bolt Holes on the Drill
Template
will be modified to accommodate the Hilti inserts.
Procedure for removing large doors on the HAM is also being worked out
(John Worden).
The dowel pin holes on the HAM Pier were found to be too small;
we will
be getting equipment to ream out the holes to the correct diameter.
