The Project Control Meeting
Agenda for Monday July 26, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
The new account numbers at Caltech
Facilities:
-----------
(O. Matherny)
New staging Building: The original contract work
is complete. Prior to
occupying the building we will pull the telephone
lines and the data link
to the OSB. The contractor started on the additional
work, the bridge and
the parking lot. We still have only one quote
for the landscaping and
erosion protection.
Compressors: Short of legal action we have exhausted
all avenues to get
our money back for the unsatisfactory air compressors.
However we found a
supplier of the satisfactory compressors who
will give us a fair value on
our compressors. If we can let a contract shortly
we should have the
compressors replaced in three months.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #43 consisting of COS beam dump parts was
rejected last week. This is the first load
of in vacuum parts to fail an
RGA scan here at LHO. The post bake
scan showed evidence of
contamination believed to be the result of residual "PROTEX" left behind
from the preparatory cleaning process and likely the result of inadequate
rinsing. Some of these parts were sent back to be electropolished
while
others were sent out to be "caustic etched". They will be rebaked
at
some future date.
Load #44 consisting of three HAM bellows was released late last week.
Load #45 consisting of three 10" optics was released this week.
Load #46 consisting of COS beam dump parts and a few IOO items is vacuum
baking and scheduled to be released Monday, 7-26-99.
Vacuum Bake Oven A's backing pump has deteriorated as of late causing
the
foreline pressure to increase from 2 millitorr to 20 millitorr.
While
not a "show stopper", this pump will need service soon.
I have not been able to leak check Vacuum Bake Oven "B"
Optics:
---------------------
(D. Cook & B. Weaver)
In this report I will recap some of the last couple of weeks activities
as no report was given. There was a lot of activity with cleaning and
baking and assembly of COS components by Betsy and Co. as well as SUS
activities on four of the core optics. We ended up rehanging and
rebalancing the FMy and the BS-2k core optics as the tilt was not correct
when they were re-hung after being baked. This was thought to be an
error
in setting up the autocolimator calibration. The optics were then
rebalanced but we were unable to make their scheduled vacuum bake load
as
the oven became contaminated by the previous load and had to undergo
a
high temperature decontamintation bake. The optics then made it into
Fridays (16th) load and back out on Monday of this week. The
previous
load of suspect parts were shipped out for a special cleaning and
processing and will be rebaked Friday. In rehanging
the FMy and the
BS-2k, the FMy was found to be OK, however the
BS-2k was found to be off
by a few minutes once again. The source of the
error seems to be coming
from the wire and not the calibration. The balance
can be brought into
its proper position with the use of different
diameter wires. It is
currently suspect that the wire is not resting
tangent to the "V" groove
of the wire standoffs. The smaller the wire,
the worse the senerio. Mark
Barton seems to have a handle on the problem
and we should be able to
move ahead with the BS-2k installation.
There is a lot of activity this week which required a lot of staging
and
preparations with three major tasks going on in the LVEA as well as
the
MID Stations. The IOO group is changing out mirror mounts and realigning
the Mode Cleaner, COS group are installing Pick Off Mirrors and aligning
them and are processing components for beam dumps etc. I have been
fighting the realigning of the FMy with the IAS group (K. Mason and
son
Dan). This is largely due to the fact that we are restricted by
clearances between the FMy and The ITMy. This recalibration is necessary
due to a correction in the FMY position calculations. The RMy-2k will
need to be realigned as well.
It was hoped that by Monday(26th) we will be staging and installing
the
BS-2k into BSC4 which will be a little more involved than some of the
other installations we have done.
Core Optics Support:
--------------------
(B. Weaver)
While Betsy was on vacation last week, Dennis and Bartie sent many COS
parts out to be electropolished or etched. These parts didn't
get clean
enough with our cleaning procedure alone, resulting in a rejected vacuum
bake oven RGA scan. We've received all of these parts back, and
have
recleaned them. One load of these parts are in the vacuum bake
oven now,
with more COS loads scheduled. This has put the COS Beam Dump
Assembly/Installation schedule a bit behind.
This week, Mike Smith, Ken Maitland, and Steve Bell are here at LHO
to
install the PO Mirrors in WBSC 7 and WBSC 4. So far, we have
assembled
the mirrors and installed one of them. Today, we will install
the other
two and align all three.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC6 (y-mid) work:
Seismic Installation is complete at y-mid (for the moment!). The
chamber
is being pumped down and we will leak check the Bellows; replace any
gaskets which may need it, and then move on to BSC5 (x-mid).
BSC5 (x-mid) work:
Have started staging items needed for installation work (we are waiting
on the fine actuation stages to continue work out there)
Coarse Actuation System (CAS) rack status:
The CAS system has been offline because of some missing hardware and
a
needed upgrade to the software. We have the hardware ready to
go,
although, it looks like one of our cables might be damaged. Once
that is
fixed, we can run a quick test on one of the motors and then work on
getting the new software on line up here.
HAM work:
For Optics Installation work, the elevation of HAM 10 needs to be checked
and possibly set--will be working on this today!
Computing:
----------
(C. Patton)
Last Friday we lost power due to a mild thunder storm. The servers
were
on UPS power and stayed online. The Cisco router to the T1 line
was not
on UPS and it went down. Turns out that when it came back online,
it
came back with its ethernet ports shut down, meaning we had no network.
It took some time to track down the problem, as the lack of a network
caused the servers to crash and they wouldn't reboot except in single
user mode. Finally, the Cisco router was re-programed by connecting
a
laptop to its serial port.
The Windows NT computer arrived for Jill to use with the new Caltech
Administration Oracle software. It's been setup in Jill's office
and
I'm still working on getting it on the network. Jill will have
to run
with two computers for a while, until everything is transferred over
to
the NT machine.
I also installed software for the vpn network with Caltech on a couple
PCs, did the usual weekly backups, added new user accounts, took care
of
accounting paperwork and helped several PC users with several different
problems.
Facilities The Louisiana State Fire Marshal paid us an unscheduled visit last Friday. We still had some items pending and he wanted to check on them. We resolved all items to his satisfaction and at this time, we have finally a legal occupancy permit for LLO. (Gerry Stapfer).
Optics: Completed the cleaning of 36 ISC viewports from MDC. Bagged and ready for bake. Inspected the reworked viewports from Varian this morning, and will begin cleaning in preparation for vacuum baking and assembling for COS. Received the additional small LN2 dewars for the SEI installation and labs. Met with field engineer from Unique systems, the local contractor who will provide a roof for the hazardous material storage bunker. Ordered a sump pump for Gerry, and installed it in the cable vault South of the East wing of the LVEA - suspected source of control room flooding. (Jonathan Kern)
Vacuum and BT: All GNB gate valves, that were repaired and/or had O-rings replaced last week, have been tested and are acceptable. We are having some small problems with two of the annulus ion pumps, and are in contact with Varian and PSI to resolve them. MMR, the BT electrical contractor is on site and has placed most of the DC cabling, it should be finished early next week. They are in the process of making the end attachments and installing the bake blankets. (Allen Sibley, Kerry Stiff)
Seismic installation: BSC#1: Installed
all Scissor Tables, Dummys, Translations Stages, Air Bearings, and Crossbeams.
Moved Clean Room into position, installed scaffolding, positioned and leveled
Support Tube Roller System, cleaned and staged all
remaining parts and tools needed for complete
stack build-up (except for parts that haven't arrived on site yet, jib
cranes, springs and seats, bellow compression fixtures.) The installation
thus far has gone very smooth and without any problems. (Rich Riesen)
EE Lab: Linux has been installed on the EE lab PC. It has the
same ability as a UNIX workstation. Some configuration issues are left
to do. The current status is that it's capable of handling two OS, Windows
98 and Linux, and the connection with the rest of GC network system has
been established. People are welcome to use it in the EE Lab. (Juilien
Svoboda)

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)
--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- Upon arrival at LLO, the 10-W laser was turned on. After a warm-up
period the output power of the laser was lower than previously recorded.
The drop in output power, approximately 0.5 W, is suspected to be due
to
the 20 mW drop in the output power of the NPRO master oscillator.
Increasing the NPRO output power, by increasing the
diode current,
by 20 mW brought the power of the 10-W laser back to the previous level.
- Armed with experience gained from last week's re-alignment of SN #107,
laser SN #103 --- located at LLO --- has also been re-aligned.
Beam
profiles of the laser's output were conducted. Measurements of
the
M-squared parameter suggest that the beam quality of the laser has
improved.
Input/Output Optics -- Dave Reitze, UF

No report received.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
(Gari has been at an SPIE conference this week.)
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
At Hanford this past week. Cleaned and suspended optics. Reviewed
balancing procedures with M. Barton and J. Romie. For details of these
activities see Janeen's report.
Core Optics Support -- Michael Smith
------------------------------------
PO mirrors have been assembled and are in the process of being installed
and aligned in BSC4, and BSC7.
Conical baffles have been ordered for the vertex and mid stations for
all
IFO's.
150 COS Table clamps for attaching the PO mirrors, and PO telescopes
have
been ordered.
Some beam dump parts were improperly made by a vendor, and have been
sent
back for rework.
9 steering mirror mounts were assembled and loaned to IOO group.
Electro-polished and caustic etched stainless steel and aluminum beam
dump
parts which were rejected from an earlier bake load have been received
at
LHO and are awaiting cleaning and baking.

1. LHO Mobil Rack (Rack #3):
Hytec has nearly completed the Mobil Rack for LHO. They are finishing
the
electronics and wiring and will install the computer and front panels.
Hytec intend to begin debugging next week. Hytec would like to have
the
rack to make software changes and be able to test those changes with
this
rack. Therefore, they suggest to hang on to the rack until it is required
at LHO.
2. Scissors Tables:
8 Scissors Tables have been shipped to LLO this past week. 8
more scissors
tables are scheduled for delivery to LHO. These tables will be
delivered
with the electronics rack on the next shipment. Again, the final 16
scissors
tables have been delayed as a result of scheduling issues. The
fine stages
have been prioritized ahead of the scissors tables, thereby delaying
the
June and July delivery.
3. Fine Actuator X-Stage:
The final 20 assemblies are currently being manufactured by Hand Precision,
four of which, due for delivery last Friday, will be shipped next Tuesday
to Handord. The PZT's and controllers have arrived at Hytec. 8 units
were
shipped to LLO. The remaining PZT's will be shipped to LHO on
the next
shipment. There are 16 PZT's plus 2 Spares that will be shipped
to LHO
and 16 controllers. It is important
to note that each PZT is calibrated
to a single controller and must be used with
ONLY that controller. Hytec has
packaged four PZT's in a single package to
be used with one chamber and the
associated controllers are shipped together.
The operators manual has the
controller number on the front page and the
PZT information on the ~3rd
page. Hytec intend to outline
this in greater detail in a short write-up (1
page) that will be sent with the PZT's. LLO will get a copy as
well.
4. Near-Term SEI Hardware Delivery Schedule:
1 set of BSC springs (LLO)
7/27
1 set BSC spring seat (LLO)
7/26
2 sets of BSC in-vacuo hardware (LLO) 7/28
4 sets of HAM in-vacuo hardware (LHO) 8/11
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Janeen:
- The FMx has been re-hung and its balance is
fine.
-The BS was re-hung. We are still working on
it. It was hung with .009" dia,
bad quality wire. We now have good quality .008"
dia wire which will bring
the BS's violin and vertical frequencies in line
with the other large optic
suspensions violins and verticals but we're having
trouble having it
balance correctly with this wire. However the
PAMs have a larger range with
the lighter-mass BS optic.
-We re-hung the ITMx and noticed a problem with
the position of the wire
standoffs. Mark has begun soaking them to remove
them. We will glue new
wire standoffs on tomorrow.
-Helena and Mark have cleaned the ETMy and are
getting it ready to re-hang
tomorrow morning.
-Re-order of the LEDs for the sensor/actuator
heads will have a lead time of
about 6 weeks.

LSC Mode Cleaner: (DAO)
================
Modified a second set of length control modules at Hanford to add
differential input on DC control lines and add series output damping
resistors to prevent oscillations when driving long cables. Also
decreased
the gain of the Test Monitor output to unity to increase the bandwidth.
Timing System: (DAO)
==============
We got the new Timing Module (GPS Clock Driver)
up and running at
Hanford!!! It is successfully working
with the ICS-110B ADC (DAQ System)
and the ICS-115 DAC (GDS System). We have three working modules and
three
more under construction. We still need to test the Timing module with
an
ICS-110A ADC (used on to 40 meter). One working module is at Cal Tech
and
is currently being used to finalize the Sync Error circuit that detects
a
loss of synchronization between any of the clocks. This couldn't be
completed until all of the timing was nailed down. The ISC Clock
Fanout
module is designed and in PCB layout now. This module will distribute
the
2^22Hz clock to the Pentek ADCs.
Many thanks to Dave Barker for his patience and persistence in helping
me
reverse engineer the timing requirements of the ICS modules. We should
be
ready to go into production (~50 units) in 2 to 3 weeks.
LSC One Arm Test: (DAO)
=================
Mohana and I have begun working on the Length Control hardware for
the
2K
One Arm Test. We also have a student building LSC photodiodes. The
LSC
schedule that I sent around a several weeks ago has slipped
significantly
due to problems with the Timing System (see above), debugging Mode
Cleaner
Length Control problems and shortage of resources. We should now be
on a
roll again. I will try to have an updated schedule by next week.
EO Shutter Controller: (S. Liu)
======================
In the process of designing a daughter board to
incorporate all
changes Peter wanted.
We need to place the orders for the following items:
1. Front panels (manufacturer's
quote is in)
2. +2KV power supplies (manufacturer's
quote is in)
3. Daughter boards
Antialiasing Filters: (S. Liu)
======================
Field test result from Dave closely matches simulation
done by
Daniel. To avoid the appearance of a "gain" of two on the differential
driver, twist pair line terminations will be done on the board for
all
future units.
We need to place orders for the following items"
1. +/- 5Vdc power supply
(manufacturer's quote is in)
2. Filter modules (manufacturer's
quote is in)
ASC Software: (RB)
================
- In process of testing ASC front end software @Hanford. Direct
connects to GDS test points and DAQS were successful. False interrupt
on startup from Pentek ADC/DAC still occurs, but managed to "Fix" the
timing problem with software. Synchronization with GPS now consistently
within a couple of microseconds.
Remainder of this week, I am adding QPD software and links to end
stations.
Suspension
=============================================
- Rewired the IO SOS controllers so that the bias adjust is added at
the
ASC input to the chassis. This elimainates the problem of bias scaling
with servo gain and bais disabling when the servo is disabled.
- Found one broken connector on the MC1 suspension system. It appears to
have been broken by repeated connection and disconnection.
- Found a broken or intermittent trace on the MC1 suspension controller
board. The trace was dammaged when the resistors in the coil driver
were
changed to increase the range.
ASC
===========================================
- Rack 2X2 (LVEA ASC rack) is 50% complete. All crates and the wiring
cross connect harnes have been loaded. Mass term cables from the modules
to the cross connects are being installed. The rack wiring should be
complete by 7/23.
- Module testing for the ASC portion of the one arm test continues.
The Quarterly Report has been sent to the NSF.

[Cindy has also prepared a table showing the translation from legacy account numbers to the new POETA account information for currently active LIGO accounts. -pel]
LIGO QA witnessed the Livingston Site large gate valve O-ring replacement activities. Gate seal Viton O-rings were replaced with Fluorel O-rings on six beam tube valves (LGV-4, -6, -7, -8, -9 and -11), and two inner corner station valves (LGV-1 and -2) by the GNB Corporation, the gate valve manufacturer. All valves passed performance testing. QA ensured that pre-approved procedures were implemented, cleanliness controls were adhered to, the valves passed performance testing, and that the process was documented. For more details of the completed activities see the trip report, LIGO-L990218-00-P, July 19, 1999.
No report this week.
The Windows NT computer arrived for Jill to use with the new Caltech Administration Oracle software. It's been setup in Jill's office and I'm still working on getting it on the network. Jill will have to run with two computers for a while, until everything is transferred over to the NT machine.
I also installed software for the vpn network with Caltech on a couple PCs, did the usual weekly backups, added new user accounts, took care of accounting paperwork and helped several PC users with several different problems.
Ran a PPP test on the modem pool from CIT which was successful on the first round. Still need to run a few more tests on different configurations before confirming the system is ready for use.
Finished loading software and moving files to the new pc.
Compacted the DCC database and refreshed their test database. Moved the Y2K changes to the test system. Y2K changes will be version 5. Version 5 also contains utilities for easy maintenance of the PerCd and Keyword tables.
Refreshed WebDocs, the internal search tool, as of July 20.
Made a few web site changes mostly to the MOU page.
Sean has been working on documenting the work he has done, as he prepares to return to Boston.
The Amaldi conference has ended with the equipment returned, only a few minor items wound up missing. The computers used at the conference have been boxed and are being shipped to the Observatories. Overall things went well.
A great deal of time has been spent in setting up users and working through the logistics of getting them on-line with the new Oracle accounting system.
It appears that the extra support will be needed for some time.
We have installed the VPN s/w at various locations and so far it has proved to work correctly.
We have purchased a portable air conditioner to handle the load in the computer room until the new unit is installed. After the installation we will use the portable as a backup unit.
With the help from ITS we were able to locate a problem machine sending out broadcast storms. The immediate problem was resolved but it took 5-6 hours to trace down the machine. The ATM cards caused the sniffer/snoop routines to give incorrect information which caused us to follow some false leads. We are lookinginto ways to resolve this issue.
Samantha has been busy installing and swapping PC's. A number of the PC's have failed and she is in the process of getting them repaired. Sam is also working with Barbara on getting the Y2K information out on a web page for everyone to use.
The usual of adding new accounts, changing
accounts, restoring and backing up data, moving computers and upgrading
the OS on some of them have been keeping Suresh busy.
Irene Baldon
Irene has been on vacation, but we expect her back on Monday.
Rita Torres
Inability to access base applications on Oracle earlier this week, however today there is improvement. Spent time with Susan Dollar and Sherri Weed to get answers to my questions regarding Oracle procedures for subcontracts. The issue of splitting a document across several account codes must be addressed by Purchasing; we will be apprised of any news here. [FYI, change order numbers as we knew them will no longer exist in Oracle. We must devise a way to identify modifications, such as administrative changes, to subcontracts.]
For I. Petrac did letter to University of Japan to transmit an MOU and attachment. Also letter to Syracuse University to transmit an MOU and attachment. Distributed signed change order No. 7 to Schober, and change order No. 17 to Hytec.
For P. Lindquist prepared book to store May reports. For M. Zydowicz sent to O. Matherny the forms, "Safety Inspection Checklist - OSB areas," and "Safety Inspection Hazardous for Technical areas." Set up two eye exams, also laser training session on 7/22/99. For Detector Group updated site trips.
Assisted visitors (some of them Amaldi attendees) in locating people and with various tasks. Ordered, then distributed, office supplies. Got a chance to update laser safety records. Contacted Pasadena Eye Medical Group for paperwork they owe us.
Dorothy Lloyd
The last time I saw any part of Dorothy, her hand was sinking beneath the waves of purchase orders inundating her office.
Elizabeth K. Wood
Helped with travel while Irene is on vacation, including locating a hotel for Irena up at Stanford despite scores of sold-out accommodations. Many thanks to Vee Cruz and her trusty computer.
Straightened out a few errors with payroll even though payroll was done correctly to begin with.
Observed Dorothy getting custom training on the new DEBACLE purchase order system. Simply observing was well worth the time spent. I’ve been told that LIGO is a test case for many ORACLE applications, hence the special care we’re receiving.
Made arrangements for a phoneline to be installed in room 360 WB for Giovanni Losurdo.
Did I mention that in the coming weeks construction will begin in room 358WB for the new CITNET2000? Don’t know when yet, and I may not know very far in advance.
Dealt with lots and lots and lots of personnel related items.
