The Project Control Meeting
Agenda for Monday January 25, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load#11 consisting of the three repaired 3" IOO
optics
(SM05-1, SM04-1 and MCCM2K02-1) as well as Qize Shu's two experimental
lenses
were released on 01-20-99. At present, the two 10" optics (MMT303-1
and RM02-B)
which will comprise load#12 are scheduled to be available for vacuum
baking this
weekend. Mike Smith's IO baffle parts should follow as load#13.
Bartie Rivera is into his second week of training and is starting to
understand
the vacuum bake oven model and theory of operation. This week, we were
finally
able to demonstrate the temperature controller's ability to dump its
data
directly into an Excel spreadsheet. This will not only decrease the
time it
takes to generate a data package but also provides for many more data
points per
bake cycle than was practical using the "manual" method.
I hope to add 10 additional thermocouples to the vacuum bake oven system
in the
near future. These will provide a more accurate picture of the temperature
distribution throughout all of the various "zones".
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
HAM work
Lee Cardenas arrived (1/18) to offer assistance with SEI work. Doors
are off of
HAMs 7 & 8. This is for final work we have on these chambers before
they can be
handed off for Optics installation. Leveling and setting of elevation
of the
Optics Tables (for actual 500 lb load (HAM 8) and estimated 500 lb
load (HAM 7))
will be worked on today and tomorrow. This work will require the activation
of
the Air Bearings. We also have some rework to do on the electronic
wiring for
these HAMs.
LHO_SEI_BSC:
Again, with great assistance from visitors from CIT Larry Jones and
Lee
Cardinas, and LHO's Corey Gray, the many small details of the BSC SEI
installation are being checked off.
The parts and fixtures we have been awaiting arrived 1-18 and the truck
was
turned around with parts and fixtures destined to LLO. Then the work
began with
the alignment of the Actuation Stacks on BSCs 8 and 1. That was completed
1-20
and the Scissors Tables(Z motion) were installed on BSC 8 late 1-20.
Next, the
remainder of the Actuation Stack (X-Fine replacement, and the X-Y Coarse
Stage,
including Airbearing) followed by the Crossbeam will be installed on
BSC 8. We
expect to finish this by 1-25 at the latest; and that will complete
the external
hardware (out of vacuum) SEI installation for BSC 8.
Optics & Lasers:
----------------
(D. Cook)
This week's efforts have been getting prepared to install the IOO optics
in
Ham7 and HAM9 and preparing for the initial alignments. The recycling
mirror installation and it's initial alignment have been delayed in
order to
make a dimensional change to the support structure. I have working
with
Helena to learn the proper cleaning process for the large core optics.
I
have also been shadowing Janeen on the magnet bonding process as well
and
modifying the fixtures. We modified the LOS screw stops by adding a
viton
plug to the end, but have not worked with them as yet. There is some
doubt as
to the conductivity of the viton. Hopefully the MMT3 optic will be
ready
for baking on Saturday, which will make them available for installation
about Weds day. If the recycling mirror structure gets baked and delivered
to the site Tuesday, it may be possible to install by weeks end.
I also worked with D Reitze and Sany doing an interesting set-up to
measure the curvatures on MMT3 and MMT2 optics. Optic transfers carts
were
test driven and seemed to roll nicely.
Modification to the straddle is almost complete. BSC door covers and
dome
covers are cleaned and in stock. We received the soft wall enclosure
in
time and had it set up over the IOT7 table for Nergis M. Others items
continue to arrive.
Any hazardous chemicals being shipped to the site
or ordered from the site
require MSDS certificates. "Heads-up"-The LVEA
will transfer to a laser hazard
condition very soon. Any additional lasers being
used for alignments etc. that
are class IIIb or IV will require approved SOP's
before they are allowed to
operate. They may also require work permits to
be filed to co-exist with other
installations and on going operations. Please
do not wait until the last minute. Thanks.
Computing Systems:
------------------
(C. Patton)
The nis+ database files have been rebuilt on rainier. All except
20
user accounts have been fully reinstated. The 20 that are left
are
infrequent rainier users. These users can still login to rainier,
but
can't change their passwords. I need to reset their passwords
as root
on rainier, after that they will be able to change their passwords
themselves. These 20 users, because they are infrequent users,
will be
changed as the need arises. I have started backing up the nis+
database
files weekly instead of monthly.
Another copy of AutoCAD has been installed on the Guest2 computer.
The
replacement key for our original copy should arrive soon.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
The cable for the Laser stop button was run to the control room; a final
location has not been decided.
Modifications to the cable tray is underway. We are encircling
the BSC's
for easier access to the seismic stacks. All modifications are
being
documented by Josh Myers so the Livingston installation will be smoother.
New electrical circuits were installed under HAM 1 and HAM 7 to provide
power to the optical tables next to these HAMS.
We worked with Jay Heefner et all on the installation of cables for
ASC and
other axillary equipment.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The Cryopump from port Y1-2 has been sent back to us repaired.
CVI
replaced the displacer motor and bearings. There was some damage
to the
unit during shipping to them( a damaged Airoquip quick connect and
bent
tubing) this was also repaired. We have performed a leak
check of all
ports on X1 module except X1-5(we are completing the installation
of the
RGA) and X1-2(we are completing installation of the just received
Cryopump). Sun River is working on blanket installation at the
mid and
corner station of X1 module, and the "portable room" built for the
corner
station is working very well. The data system has been moved
and powered
up. We have added some additional channels to record main turbo
and aux
turbo "run" signal and aux turbo pressure signal. Ed Watt has
completed
the insulation work on X1.
Detector installation related activities (Rich Riesen): Core drilling for the HAM pillars has started. 20 holes have been cored so far without problems.Rich is continuing to order equipment for Detector Installation as well as general supplies needed for other on-going tasks.
Bake oven (Kerry Stiff, Allen Sibley): We installed heat trace tape and insulation on the vacuum bake oven UHV piping. We also tested and tuned the heater controls. The RGA Computer for vacuum bake oven has also been assembled and installed.
Electrical issues: (Juilien Svoboda) Juilien has been assisting Bill Parker to do the EMI survey test. This is a repeat of the testing which has been done in Hanford.The EE lab is still continuing to be set up. Many small parts and tools are still on order. All packages for our open shelves and modular cabinets from Equipto have finally arrived completely. It has been a struggle to get them here undamaged. We will now have enough space to keep parts and equipment. Juilien has also begun preparing the temporary network for the LVEA and mechanical equipment room, ordering enough Cat V cables and figuring where and how many of them will be needed. Manpower might be needed as we start laying the cables next week.
She is also preparing a VMEbus test setup so that we will have a away to diagnose and repair electronics modules. She started talking to a few vendors for the 19" rack and VME chassis. She will do more studies on what kind of CPU board and extender to buy for our testing purposes.
Facilities Issues (Gerry Stapfer): The electrical QA work by
WYE Electric has been completed and accepted by LIGO. A similar effort
has now been started by Bernhard, the mechanical contractor to Hensel Phelps.
The work consists primarely in straightening out the "as built" drawings
replacing numerous carbon steel pipe fittings
with galvanized fittings and inserting anti galvanic pieces between
copper and steel connections. During a meeting with Bernhard, they agreed
that this "fixing up" task is part of their contractual obligation.
The well water pump at both end stations has been reinstalled in an
enclosure to keep them from freezing up and permanent electrical power
for the pump has been connected.API has started another round of blister
fixing. This time, they are injecting adhesive into the small holes and
they will flatten the bubbles with a small
vacuum pump.
On Tuesday we found another bullet hole in the west end station. It is located high on the east wall, indicating that the shot came from a different location than the previous ones. The appropriate authorities locally and at the NSF were notified and reports have been filed. Investigating this incident we found that the fence was cut (at a location at the backside of the enclosures where the pipeline crosses under the berm on the west arm.) This was reported to the authorities as well. Fortunately the hunting season (for shooting deer with rifles) closes this weekend. This should quieten the area considerably.
(Rich Riesen): The end-stations well pump slabs and enclosures are complete. 90% of the electrical is complete and water piping has not been started yet.Direction signs for crane operation is 50% complete in the LVEA, have not started on the end stations yet.The sling and shackle storage fixtures are complete and being stocked now.The forklift/genie lift on-board checklists are completed and installed.The Control room furnisher is being changed out for the proper colors and should be completed in approximately 4 weeks.
Optics & Vacuum Labs: (Jonathan Kern): The Culligan RO/DI
system is not on line yet. Culligan installed a pressure, rather than a
circulating, pump which works
itself to death, eventually overheating and shutting down. A different
pump has been ordered. When it works, we have seen 17meg-ohm water. Our
second 4x10' optical table arrived and is assembled in the LVEA. We'll
move it in place this afternoon after Caroline cleans (once again!) the
floor. No word back yet from the freight line on the damaged flow benches.
The bulk of the optical table hardware was ordered last week from Opto-Sigma.
We're ramping up for the PSL crew; Peter King is in the loop now and we
spoke this week about his imminent needs. The PSL safety enclosure needs
to be ordered. Vendor quotes and an option that I think will work well
are on this page
<ftp://ligo.caltech.edu/pub/Livingston/PSL_encl/index.html
Detector modelling (Anthony Rizzi): Anthony Rizzi, Hiro Yammomoto and Tom Evans have started the process of putting the end-to-end model software on a Sun on site.
PEM (Anthony Rizzi): The PEM cart electronics has been given
a baseline check and is found still in need of one set of cables and a
resolution to network hookup problems.

Updated the LIGO contingency log and initiated a reconciliation to the PMB. Continued to reconcile the LIGO actual costs to date with CIT finance.
Reviewed the PSI monthly report for December 1998
for correlation to the LIGO schedule. Advanced the calender in Open
Plan and initiated the
December 1998 update.
Began preparation of presentation materials for an abbreviated cost/schedule review planned for Monday, January 25.
A decision has been made to proceed with Phase I of the irrigation and
landscaping for the Livingston site. A CCB will be convened to take
$250,000 from contingency for this effort.
The Invitation for Bid for the beam tube insulation for bakeout [Livingston] will be issued early next week. The current schedule calls for award by the middle of March.
Parker-Hannifan/JBL has submitted a bid and is planning to ship a Fluorel sample by the end of this week. Another local cord extruder has now indicated an interest in talking with us regard our o-ring procurement. At this point it's not clear if this vendor is extruding Fluorel without wax or other similar additives (a discussion with their extrusion manager is pending).
LIGO QA is continuing to "audit" the PSI documentation submitted for
the Livingston vacuum equipment and supported (via phone) the PSI/LIGO
final acceptance review and monthly status meeting.
* Modeling
Adlib - optics modeling
We have solved a big problem and finished a debugging,
and we feel
that we have cleared major toughest part in implementing
optics based on
the time domain modal model, including mismatched
curvatures of mirror
surfaces. The following is the near term
plan of our optics related part.
(1) Validation mostly using Ray Beausoleil model and twiddle.
Validations related to lengths have been completed,
and misalignments
in a FP system has been tested. The rest are mostly
angle related
cases for the full LIGO-like configuration.
(2) Setup for LIGO like configuration with servos with the same complexity
as SMAC, but have mode support, and a users manual
how to use this
package.
(3) Source code cleanup.
(4) Detailed physics documentation about the implementation of the
optics
in e2e.
Positioning information to mirrors, x,y,z,picth,yaw, are now combined
into
one data type, clamp.
Alfi
(1) Implemented the same naming mechanism as AdLib for port names.
(2) Started profiling the ALFI code to see where to speed it up.
(3) Corrected line coloring problem when one side was connected to
a port
of unknown data type.
(4) Added renaming capability to ports.
* LIGO Data Analysis
EFM - Worked on getting metadataAPI.so to communicate with DB2. Currently
working on wrapping basic
functions for TCL.
XH - worked on GDS database tables.
XH - worked on frame database queries.
XH - practiced the DB2 CLI and ODBC classes.
* General Computing
MIT:
Nothing to report
Livingston:
Nothing to report
Hanford:
The nis+ database files on rainier have been rebuilt. There are
still
some user accounts that cannot change their passwords. If anyone
runs
into this problem on rainier, please call or email Christine Patton
at
LHO.
The new license for AutoCAD14 arrived and has been installed on one
of
the guest computers. The replacement key for our other copy of
AutoCAD
should arrive shortly.
CIT:
Barbara has added a field to the web application for reserving a document
number. Now you may pick a requester from a pull-down menu or
enter the
requester id directly. Reworked the web MOU page. Added a large
number of
MOU attachments, broke into LSC member and non-member tables, and
rearranged the table entries to be more readable.
Added more SURF projects and made other small web site changes.
Samantha has been rebuilding PC's and redistributing them.
Larry has been in contact with LSU concerning the vBNS connection to
the
Livingston Observatory. Larry and Albert plan on meeting with LSU and
the
South Bell rep. at the end of February to discuss the connection.
With the problems the main webserver has with
automount, the directories
being accesses the most have been hard mounted.
This has solved the
"privilage denied" issue in most cases. A few
other cases still need to
be looked at.
The CD burner for general usage has been installed and tested. The
instruction sheet on how to use the burner will be posted in the cubicle
where the burner is located by next week. The scanner should also be
installed on the same unit next week.
The OC12 connection to CACR has been put in and Stuart is testing it
out.
So far it looks pretty good.
Two more computers that had problems from the power hit a few weeks
ago
have been repaired by Suresh.
The memory for the Livingston box has arrived and Sean is now working
the
issue to improve the performance of the modem pool.
Irene Baldon
PLEASE NOTE: As of today (1/20/99)I have no backlog. All Expense Reports turned in have been completed and are in the hands of Travel Audit. My backlog is .
Worked on the paper work for various new trips taken recently (17 Purchase Requisitions and 9 Advance Requests). There are 9 additional new trips pending completion of travel arrangements. Completed 38 Expense Reports, some of these were still not taped or completed by the Traveler. As a result of the push last week to clear my backlog, I have had extensive recording and filing to do this week.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as for members of the staffs of each of the two (2) sites.
Due to a few recent situations, I thought a clarification on LIGO related Foreign Travel would help.
Since LIGO is a Government sponsored program, with funds totally covered by Government money, it is VERY important that all foreign travel be handled exactly to Government Regulations. You or your invited guest should ALWAYS contact Irene Baldon or Vee Cruz directly and have them arrange the trip. In the case of a guest coming from outside the United States we can contact them directly by e-mail and arrange everything to their satisfaction without you having to hassle all the many details and rules involved. We can issue them E-Tickets ["Electronic"-Tickets are similar to Prepaid Tickets in that the Traveler simply goes to the Air Carrier's Check-In Desk and shows them his/her Itinerary, which I'll both FAX and mail to them, Photo Identification (Passport, Drivers License, etc.), and then is given his/her ticket and Boarding Pass, with no cost to them] or Prepaid Tickets wherever possible. (We recently were able to issue E-Tickets for two guests coming from Russia.) Again, your guest will not have to put forth any of his/her personal funds and if an Advance is necessary, it can be ready for their arrival since I'll have all the information available to me. If these rules are not followed exactly, and you or your guest make your own arrangements using foreign air carriers entering or leaving the United States, LIGO WILL NOT BE ABLE TO REIMBURSE YOU OR THE GUEST FOR THE COST OF THE AIRFARE.
*** THERE WILL BE NO EXCEPTIONS. ***
Thanks in advance for your help and cooperation in this difficult matter. If everyone follows the rules all can, and will, go smoothly.
