The Project Control Meeting
Agenda for Monday March 8, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
BSC8 pumped down for test of leak tighteness of seismic
seals
New power limit on red lasers at LHO
LLO main access road construction has started
up
=========================================================
LIGO Hanford Observatory (LHO) Operations (F. Raab)
=========================================================
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #18 consisting of three
BSC bellows (S/N 017, 031 and 032) has been vacuum baked but
has not been unloaded. These followed the release of load #17
(MCCM2K01-1, MCCM2K02-1, MCFM01-1 and MCFM06-1) last
week.
Load #19 (three BSC bellows + misc. SS) should begin
vacuum baking tomorrow.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Downtube was installed and connected to the Support Tubes. Noticed
that the
V-Blocks for the "Eastern" side of chamber were
not in nominal position.
It was discovered that the Air Bearings (which
were "centered" prior to
in-vacuum
hardware installation) had lost their centeredness--giving
the undesired
connection
for the Support Tube/V-Blocks. Air Bearing
Centering fixtures were
re-installed,
and Air Bearings were activated to get Air Bearings
back in their nominal
positions.
All Bellows were then installed. One item to note was that the
16"
gaskets were
tricky to seat into their respective conflats, but they were eventually
seated ok.
Chamber was then sealed up (dome and 60" door were re-installed).
Chamber
is being pumped down currently and leak testing
is slated for next task on
BSC 8.
HAM 10 Work
Because of schedule freedom, installation of the
stacks into HAM 10 has been
bumped up and will begin end of next week or
the following week. The Support
Tubes and Crossbeams were mated up, via V-Blocks in preparation for
upcoming work.
Optics & Lasers:
----------------
(D. Cook)
The Recycling Mirror was installed and aligned
into HAM 9 last week.
Thanks to all who participated. We had some new
team members this time,
which adds to our experienced work force and
new members bring helpful ideas.
We
have transitioned back to the Laser Safe Condition do to some
technical
problems that will cause a 2-3 week slip in the
detector installation, at
least as far
as needing the IR laser in the beam tube.
We are still processing the ITM
and FM
for the 2K in hopes of installing them into BSC 8.
We are working on the optic
levers for the MMT3 and RM in order to
monitor
these optics. This is important as we have a lot of on going
activities
and we are not
sure of how the pumping and venting of the chambers may effect alignments.
We
have found that the level of the tables are important as it effects
the
OSEM locations,
which effects the damening. As we add componets to the optics table
and
remove the
counter weighe the level needs to be checked.
Although
it was not a design requirement in the beginning, we are
limiting any
of the visible wavelength lasers coming to Hanford
to less than
5mW (class IIIb = < 4.9mw @ 633nm). It becomes
expensive to write, maintain
and
enforce Standard Operating Procedures, which
are required, if we use class
IIIb and
class IV lasers. These Standard Operating Procedures
have to co-exist with
other
SOP,s that are already in place. By staying below
a class IIIb systems we
can avoid
having to double up on eye wear requirements
which adds to the expense and
makes
it much tougher to work (wearing two pairs at
times). If we all know that
when we see
a Red visible beam that we are safe, do to the
low power level, it will
create a more
comfortable working environment. We will be using
several 633nm lasers for
alignment
as well as the optical levers which need to be
on continuously if possible,
and so to keep
from having to evolve into an even more complicated
and more expensive
laser safety
program please keep this in mind. We will still
educate and inform people
as these low
power systems are put in place.
We
had a couple of laser incidences last week , because procedures
were not
followed. It did not involve any personnel being
injured, and only minor
property damage
occurred, but it should not have happened. If
you are involved in a laser
related incident,
you will be asked to fill out the proper forms
for review by the Site
Safety Board, and
then they are forwarded to Pasadena for review
along with becoming the
"Guest of
Honor" at Otto,s Tuesday Safety Meeting where
you will enjoy the comforts
of the
"Hot Seat" where you get to explain what occurred.
We have installed a fourth
laminar flow bench in the Vacuum Prep and
Assembly area. We now have our mill and lathe powered up in the warehouse.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
Early in the week we had a
big push in diagnosing problems with the OSEM's.
After taking multiple measurements over 2 days
it was decided to ship all
available OSEMs back to CIT. We removed
all of the OSEMs from the
existing optics with the exception of MMT3 and
the Recycling Mirror. (GHS note: The OSEMs are being replaced due to a
molybdenum layer that is causing damage to coil insulation.)
On Wednesday worked with Stan W. on the Optical Lever for MMT3.
We had a
lot of problems with controlling the mirror.
After investigating the
situation, it was apparent the table was
no longer level causing the
magnets on the optics to be misaligned with the
coils. Stan re-leveled the
table and the mirror dampened quickly. We are now logging the
data for the
mirror.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
Sun River has moved all of the DC cables and "D2" boxes from X1 to X2
and
has completed the termination of the cables. They will begin
to move
blankets from X1 module to X2 module. We have removed Cryopumps
from
X1-2, 3, 4, 6, 7, and 8 and are currently bakeing ports X1-2, 3, and
4.
The RGA is currently baking in preparation for the post bake measurements.
Detector installation support activities: (Allen Sibley) The first load
of
bellows has been removed from the vacuum bake oven after a good RGA
scan. A
new load is being placed in the oven and will be baked this week.The
PEM RGA
on HAM 5 is being baked in preparation for a base line scan of the
VE.
(Juilien Svoboda) EE Lab: I have made a laboratory equipment list on
the
LLO's web page(not linked with LIGO's home page). whoever is interested
,is
welcome to visit this site at
http://www.ligo-la.caltech.edu/~juiliens/electronics_lab/inventory.html
VME test stand setup: Reference books from Wind River have arrived.
Since we don't have any spare controller board to download test files,
I can only study the existing codes located at LLO's CDS server.
(Rusyl Wooley) 3) - 2" conduits have been installed at the corner station
Control Room, Mass Storage Room & Computer Room cable tray installation
is
complete.Started conduit installation at the south and east end stations
for
the installation of the temperature sensors
Replaced all the twist lock receptacles on the dedicated 120vac 20amp
circuits with general purpose receptacles at the corner station
Ran (3) additional 20amp circuits to the PSL enclosure
Walked down the south and east beam tube enclosures for final check
of fiber
and copper installation; some debris found at X2; gave MCA permission
to
terminate fiber; received cut sheets for epoxy coating that will be
used to
cover the EMT that was installed outdoors.
Marked cable tray component specification which has now been forwarded
to Ed
Jasnow.
Beam tube bakeout: (Cecil Franklin) We are in the process of reviewing
and
rewriting the Beam Tube Safety Procedures.
Kerry is in the process of ordering Safety Equipment also equipment
supplies
needed to install lighting at the BTE entry doorways.
We are working with the Baton Rouge Door supply Co. to purchase special
bake-out specific locking tumbler for the BTE to be used during the
Bake-out.
We have setup a meeting next week with the local Signs Co. to discuss
our
signs requirement during the Beam Tube Bake-out.
Optics & Vacuum Labs: (Jonathan Kern): ): Lab water quality is improving;
we're approaching 16 meg-ohn in the general system, and 18.3 meg-ohm
at the
optics cleaning bench. A cabinetmaker came Monday to repair shipping
damage
to one of our flow benches, and I found them to be very dirty inside.
Of
concern is adhesive contamination inside the air delivery system. AirTech
connects the blower to the plenum with a homemade sleeve that appears
to be
vinyl. It is a sheet rolled and overlapped, bonded with some cement.
Whatever adhesive that was used has been spilled inside the sleeve,
fan
housing and onto the squirrel cage. See
ftp://ligo.caltech.edu/pub/Kern/AirTech/images/qc4.jpg
AirTech sent a
partial shipment of 5 work tables, as well as the replacement sink
unit for
the optics cleaning bench, which was received damaged. See
ftp://ligo.caltech.edu/pub/Kern/AirTech/Mar_2_Damage.html
We're waiting on 8
more work tables, as well as 2 soft-walled enclosures for suspension
and
optics work in the labs. We moved the last 4x10" optical bench into
the
Vacuum Prep lab last Saturday, and yesterday completed the fine location
and
levelling of the PSL table and table enclosure in the LVEA. The Laser
Safety
Enclosure for the PSL was scheduled to ship this week, and we expect
to
begin installation as soon as it arrives. Received a final batch of
table
hardware from Opto-Sigma, as well as a truckload of LISTA cabinets
and
roll-around toolboxes for both labs. All of the lab garb items are
on hand
for detector installation. I also received a large air-bake oven from
VWR,
and well as a second ultrasonic cleaner and sundries for the bake-oven.
Ordered but not received is a large HEPA vacuum cleaner for the LVEA,
along
with safety carboys for storing methanol and ethanol in the labs. Cleaned
the small lathe that Ed Chargois obtained for us, and that is now up
and
running. Received quantities of tooling for it, as well as a 14" metal
cutting band saw, a square wheel grinder, and 2 8' workbenches for
our small
instrument shop in the staging building.
Anthony Rizzi: The weather station hardware was installed by James Finney
on
Tuesday. Weather software installed and system check and final
hook up to still in process.Wilcoxon accelerometer cable not found.
Work
continues on end-to-end modeling. The remaining suspension test bed
parts
are being crated and sent by Jay Heefner
Facilities: (Gerry Stapfer) Construction
on the Access road has started! We
met with the contractor and the construction
manager to inquire about their
schedule but could only get a vague promise for
completion by October. The
primary access road is now closed to all LIGO
traffic. Until the
construction is complete, all visitors,
suppliers, and staff must use the
by-pass road. This road turns off Hwy 63 about
two miles earlier i. e. two
miles closer to Livingston.
Views of current activities underway at LLO may be viewed at:

40 m Interferometer (Nergis Mavalvala)
---------------------------------------
We continue tune up of the interferometer.
Careful remeasurement of damping gains for
critical damping have been performed, and
gains have been reset to avoid output (to
individual OSEMS) saturation. The damping (with globals)
now seems as good or better than pre vent.
The most sensitive configuration to misalignment
and Guoy phase uncertainty is the power recycled
Michelson but with the Carrier resonant. Previously
we had discovered how to lock this. Now we have
investigated in detail its gain and alighment properties.
When consistantly the SB resonant PRM gain is measured,
a number of parameter invariant quantities are [in principle]
determined. THis study has been now largely performed with
good results, useful for a recycling paper.
In the wake of concern over Flouro carbon contamination
of LIGO optics we have re-examined the 40m evidence.
It turns out that the 40m MK II historical record clearly
shows a significant "CF3" signature that is constant
and residual after initial pump down. The actual optical
loss history of 40m optics is murky but with a trend of
degredation not inconsistant with some uniform "chemical"
type contamination. We continue studying these losses and
their history.

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Interferometer sense/control (Zucker)
-------------------------------------
Component delivery status:
ISCT7 parts by
3/18
ITM optical lever supports (see Matt's report below)
ISC fab (MZ for Nergis Mavalvala, Peter Fritschel)
---------------------------------------------------
There was a purchasing delay for the ISCT7 integration
cleanroom components at LHO so the cleanroom will not be
ready. Fortunately there is a BSC cleanroom which happens
to be otherwise free during the proposed assembly time, so
we'll use that for the time being.
ISC Supervisory Control Code Development (Ed Daw)
--------------------------------------------------
This week I have been tidying up my DDCU code for
ASC and starting documentation in doc++. I am
now at the LSC collaboration meeting in
Gainesville until Saturday.
IAS Initial Alignment / ISC design (K.Mason, M.MacInnis)
--------------------------------------------------------
Myron has completed approximately 90% of the subassembly of ISCT7.
He
will start packing Monday for shipment on 3/10/99.
A plan was written to replace the Sensor/actuator heads on the LOS using
optical levers to maintain alignment.
Layout design of ISCT10 has been completed.
#MZ note: this layout will
be circulated for comment shortly.
For reference, ISC10 handles
the "dark port" as well as the
pickoffs, and is the most
complex of the sensing tables.
ISC fab (Matt Smith)
---------------------
The kinematic plates are complete for the Optical Lever table assembly
for the 2K input test mass. They are sheduled to ship this
week to
Hanford. The table and legs are also through machining and are
waiting
paint. The support structure for the photo diode has NOT been
machined
yet. They slipped a week in the delivery and are now scheduled
to ship
the week of the 15th. I am pushing them to get this finished
sooner.
All the hardware(screws, bolts, ballbearings,etc...) has been delivered.
#MZ Note: This delay should not directly affect
the ITM installation
due to independent slips in
ITM installation. However
it will mess up our travel/integration
schedule,
since we may need to add a
special trip to integrate it in
advance of the ITM installation.
I am just about finished with the top-level assembly drawing for the
optical lever tables. I need to provide Hanford with the hole
locations for the hardware to hold the legs in place.
The remaining pieces for the ISC7 table are out for quote and will be
ordered this week. These are those items that we had spares from
the
first set of tables (IOT7 type) that were borrowed for the ISC7 table.
The purchasing of these items have no effect on the delivery of ISC7.
The last parts for ISC7 are due early next week.
I have not ordered accoustical blankets for this table yet. I want
Peter to test the first set to ensure their effectiveness.

Lasers and Optics -- D. Shoemaker for 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
--------------------------------------------
- The remaining vacuum equipment necessary for the PSL reference cavities
has been ordered. These items include the ConFlat non-rotatable
blank
flanges, the all-metal shutoff valves, copper gaskets ... etc.
These items
were all one week delivery items and so should arrive late next week,
ready
to be scheduled for cleaning and baking.
- Preparation is continuing towards a design review. The documentation
is
being finalized.
- The AOM used for stabilizing the intensity of the PSL has been repaired
by Isomet. They concluded that the PZT had become unbonded from
the sonic
transducer because of a fault with their electronics. Even at
the minimum
setting of the analog driver, the electronics delivered too much rf
to the
AOM. The AOM should arrive at Caltech on 03/08.

------------------------------------------------
2K Installation -
Our policy of running small optics spares though the optics preparation
procedure was a partial success. Of the four mirrors that were baked
(2
MCCM and 2 MCFM), only one MCFM came through the cleaning process in
tact.
It has been suspended. We have reglued the two MCCM mirrors and
will bake
them on Friday.
All of the 3" optics have been characterized for transmission and
reflection. All are in within specification.
20 mW of the PSL beam was send into the vacuum system to align the
IOO periscope and first steering in vacuum steering mirror.
The OSEM problem has delayed the installation
of the remainder of the
SOSs. As of right now, SM1, SM2, and MMT1,
and MMT3 are in HAM7. These
will be removed to have new OSEMs retrofitted.
We measured the beam size of the Mode Cleaner (MC) waist at the
effective MC waist location. The distance from the bottom mirror
at the
periscope to the MC waist to be 136", taking into account the beam
path
passing through the first MC flat mirror and the viewport. The
beam size was at the end of the beam path using a beam scanner. During
this measurement all the optics were exposed to ~6.5 W. When the three
mode matching lenses were set at 85", 119" and 172", respectively,
from
our reference point, that is at the center of the second EOM, the measured
beam size waist size was 1.86 mm, the designed waist, and the beam
divergence was correct. Some difference in the measured vertical
and
horizontal spot sizes was observed. We traced this to lens MCMMT3,
which
was slightly displaced and tilted with repsect to the beam path.
4K Interferometer -
Small optics suspensions and non-suspended mirror mounts are currently
in
production.

ELLIPTICAL BAFFLE/BEAM DUMP
A flat glass packaging specification was written by Ed Chargois and
Mike
S., and has been sent to the glass fabricator. New glass baffles will
be
cut and shipped the end of this week. A local glass company is in the
process of polishing the inside edges of a sample elliptical baffle
hole,
and will have the results by the end of this week. The reworked elliptical
baffle mounting structure will be completed by the end of next week.
ITM/ETM ARM CAVITY BAFFLE

1. Electronics Rack:
Hytec has completed the assembly of the side panel, MUX, pneumatics
and their
respective interfaces to each other and completed several tests to
validate the assembly of the electronics rack prior to integration
with the
BSC prototype. They have begun to integrate the rack with the
BSC prototype
and expect to be complete and ready to begin testing and breakin operations
tomorrow.
2. Scissors Tables:
Hytec has assembled the eight scissors tables with the exception of
the IDC
vertical actuators. These actuators were expected to be shipped
on
2/19/99, however Hytec has yet to receive them. After checking
with MSI
technologies, Hytec has been informed that they will not be shipped
until
3/5/99. This will delay the delivery of these eight scissors
tables to
LHO.

-------------------------------------------------------------------
1. LOS Structure:
Mark Barton found an assymetry in the ITM's structure
that is mysterious.
Janeen is working with Brookfield to determine
how this could have occured
and will measure the other structures in the
So. Annex to determine if this
assymetry may be found on more than one structure.
A work around has
been proposed and Mark is implementing it.
2. Alignment Fixture:
Janeen is working on redesigns for the alignment fixtures that are
needed for a suspension installation in a BSC chamber.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
------------------------------
John Zweizig
I finished rewriting the data distribution subsystem of the data monitor
tool. I wrote a C++ interface class to get frame data from the Network
Data
Server. This was debugged on both big- and little-endian machines using
a
test-version of the DAQD program. I then modified the Data Pusher application
to use this interface to write frames directly to the shared memory
buffer.
I fixed several bugs in the root and background environments deftly
located
by Bruce while I was demonstrating the prototype analysis environments
to him.
A few bugs were also discovered in FrameCPP and were shaken out by
Dave.
I participated in discussions which should lead to the definition of
a
standard algorithm library and I prepared for and attended the LSC
meeting
in Gainesville.
Daniel Sigg
1. Wrote an outline for the GDS FDR.
2. Finished the documentation on the data representation for diagnostics
tests.
3. Prepared for the LSC meeting in Gainesville.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
Caltech delivered 8, 3/4", spacers that are
to be used for the PEM
interface plates to WHAMS 7 and 8. These can be installed anytime.
(Alex will be at Hanford, Monday.)
I had designed and sent out for fabrication the
temporary interface
plates that are to be used for the PZT shakers. These plates
will bring
the center axis of the shakers in line with the center of the seismic
support tubes. The new PZT shaker masses are finished and at
Larry
Larsons machine shop waiting for delivery.
The seismometers still have no believable delivery
schedule. We have
purchased 10 sets of interface connectors for the seismometers.
Ralph
Burgess is assembling cables for insitu data collection.
I redsigned the Electromagnetic shaker assembly
parts so that shakers
can be locked in place for transit.
Accelerometer cables are due to be finished this
Friday by Endevco.
Worked with Livingston to run the RGA. The
RGA needs to be baked and
they are working on that.
Optical Contamination (Daqun Li)
--------------------------------
Two weeks of data have been gathered for the fresh set of viton seats
currently residing in cavity two with no increase in losses observed.
I will start vacuum cycling the cavity and keep taking data.
The second turbo pump is still under vacuum baking/pumping and will
be
ready early next week to start a paralell viton test in another cavity.
No data degradation has been observed in our contamination test cavity
from the clean optics which were cleaned by CO2 snow. Following is
a brief
summary of the data taken from the same mirrors before and after the
CO2
cleaning,
Before CO2 cleaning: 137.67+/-1.87 ppm/cavity for total mirror loss
1.04+/-0.06 ppm/cavity for absorption loss
After CO2 cleaning: 133.33+/-3.56 ppm/cavity for total mirror
loss
1.14+/-0.11 ppm/cavity for absorption loss

Week of March 2, 1999 - LIGO QA received the set of Fluorel O-rings for the 44 inch gate seal. These O-rings along with some splice joint samples, have been sent to R. Weiss for vacuum bakeout processing. Assuming they successively pass the backout, they will be sent to GNB for installation in a 44 inch gate and subjected to a 150 degree C bake with a closed valve "loaded" condition.
The fabrication of 48 inch gate seals will be completed in the next
two weeks. The seals will then be sent to R. Weiss for bakeout.
Modeling(EFM) Produced another verison of Alfi. This version corrected several problems experienced at Florida site.
Data Analysis(BAK) Created DB2 database/tables for CDS' channel configuration file. Loaded
(DF) Met with Kent to discuss compression of Frame vector objects (FrVect)
and the method for returning contained
objects in the FrameCpp library.
(DF) Fixed a bug in the FrameCpp library which caused multiple frame
reads
to fail.
(DF) Added support for compression the FrameCpp Vect class.
(DF) Added Complex data type to FrameCpp to support the COMPLEX_8 and
COMPLEX_16 data types.
(DF) Met with Benoit and Albert to discuss FrameCpp library.
(DF) Finished all Frame API commands except for 'createFrame'.
(EFM) Got the first verion of the metadataAPI to send queries and retrieve results.
(PSE) Wrote the service.tcl namespace script to replace
and extend the resource file parsing
facilities of the
various Tcl API's.
(PSE) Registered all my Tcl code in the central CVS
repository.
(PSE) Wrote the errorstats.tcl namespace script to provide
on-the-fly statistical analysis
of error conditions reported
in the logging system as a system
management and debugging
aid. The managerAPI.tcl
will source this script.
(PSE) Identified the need fo a debugAPI.tcl providing modular
debugging facilities to allow
stand-alone testing of API code
and simulation of system resources
for the testing and
debugging of system components.
(XHU) Refined LDAS database tables. The LDAS event tables are modified
according
to discussion with Albert, Kent,
Hiro, and Barbara.
(XHU) Worked on database documentation.
(XHU) Tried to establish a connection between spica and Barbara's NT
machine.
The connection is not stable.
I'll see if I can fix it.
General Computing(BAK) Loaded NT Workstation onto a new PC.(BAK) Attended a meeting about the Safety and Operations Procedures web pages.

For I. Petrac did edits to MOU with Stanford University, with four attachments. Did edits to MOU with Cornell University, with two attachments. Did edits to RFQ IP-310 for Cable Tray Fabrication and Installation at LA; RFQ still in work.
Met with Safety committee, including J. Kern, to discuss procedure for obtaining prescription laser glasses. Also met with L. Turner, B. Kratochwill, and W. Tyler to discuss safety and operational procedures. Any documents posted on the web must be current.
Obtained DCC numbers and formatted four checklists from Hanford (operational procedures), sent to LHO for signatures. These will be placed into the DCC and on the web once we obtain CIT management signatures.
Arranged for an eye exam.Formatted memo, then distributed for S. Whitcomb. Ongoing updates to site trips on the web page. For P. Lindquist distributed Annual Work Plan, then FedExed to NSF. Helped I. Baldon copy some travel documents.
Dorothy Lloyd
Continue to work on reconciling the status reports. Processed the usual heavy load of purchase requisitions, POs, change orders, etc. Tracked and tried to resolved problems involving invoice payments. Processed many invoices and receivers for payment. [See Cost Schedule Control Systems report submitted by Sarita Moore for further details.]
Boxed "1997 Closed PO" files for inclusion to DCC and redistributed file space for 1998 and 1999 files.
Continued to monitor and support the temp.
Irene Baldon
PLEASE NOTE: I took some vacation days thus my report only reflects 2 days, plus 1 day of catchup.
Worked on preparing the paper work for various new trips taken recently (9 Purchase Requisitions and 6 Advance Requests). There are 16 additional new trips pending completion of travel arrangements. Completed 6 Expense Reports. Some of these were still not taped or completed by the Traveler and required more time for completion.
There are still 10 - 1998 folders to be cleared and sent to DCC for permanent storage. These are folders containing Visitors, Consultants, and various conferences. While pulling the 1998 individual files I found a number of trips not completed with the submission of an expense report. I have been contacting these individuals as time permits. Please submit your receipts if you still have an outstanding trip. I have only received a couple of 1998 expense reports. Please send me you receipts as soon as possible.
Prepared Travel/Vacation Itinerary for the Week of March 4th, 1999.
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. Also worked on a number of problem issues which required a portion of my time.
Elizabeth K. Wood
Got a temp to help Linda Turner out in the DCC.
Helped Irene with her backlog of travel expense reports and covered for her while she was on vacation.
Talked to the Service Center about the air conditioning problem in Bridge Annex. Turns out there are two air conditioning problems down there, one that affects the computers and one that affects the rest of the basement. A technician came out on Tuesday and to the best of his ability has fixed the problem in the fax room. The problem is that Bridge is a very old building with very old HVAC.
Sent out the mailing for the LRC elections (as per Robin Stebbins) and began clean-up of incorrect/non-working addresses for the LRC database.
Dealt with the usual personnel issues--new job listings and PAN forms.
