Minutes, GLAST
Tracker Technical Meeting
Here are
today's meeting minutes:
ACTION #1- Jeff Tice to send the Face sheet
prepreg invoice and proforma data to Sandro.
If we prepare the invoice and prepreg proforma as was done with the
sidewall prepreg material, INFN and Plyform would have no problems with Customs
or taxes.
ACTION #2- Jeff Tice to provide status of Carbon-Carbon
material order and delivery schedule.
ACTION #3- Steve Lundgren to purchase and supply
to INFN three (3) additional cables that are used to download data from the
Tower Environmental Measurement systems.
DISCUSSION:
INFN NCR
#192- Reviewed and accepted repair. Approved tray to progress.
INFN
reported that Tower 1 Vibe successfully completed. Post-Vibe CPT in process.
The T/V
chamber door is scheduled to close tomorrow.
Pump down will proceed over the weekend (I think that's right) and Thermal
cycling will start Monday morning.
Peter A.
is scheduled to arrive in Pisa on Friday at 12:15 p.m.
INFN will
meet Peter at the airport, pick up the Flex Cables and bring them to INFN.
Peter A.
will hand carry back to SLAC the C3-08 Flex Cable (with damaged connector
pin). This Flex Cable will then be
shipped back to Parlex for connector replacement.
Peter
will also bring back an environmental recorder (used during shipment of
Towers). This environmental recorder is
to be returned to the supplier for repair.
Emilio
sent comments regarding Tower 1 alignment (ref. e-mail sent 3/3/05 @ 4:08
am). Arthur needs to set-up a brief
meeting with Dave, Martin, and Robert Ruland to review his comments. We will call Emilio to discuss any issues.
EMI taping-
Notified
INFN that rollers to perforate the EMI tape have been sent. Please confirm receipt when received.
Team
agreed that SLAC (Steve Lundgren) will perform EMI taping on Tower 1 and Tower
2. Not sufficient schedule time for INFN
to perform EMI taping on Tower 2.
Plan is
for INFN (Riccardo) to perform first article EMI taping at INFN on Tower
3. Dave Rich offered Steve Lundgren to
assist Riccardo on INFN first article.
This is recommended to ensure that lessons learned and workmanship
issues are addressed to prevent any recurrence.
We will watch the Tower 3 EMI taping schedule. Perhaps Steve could hand carry the Tower 4
MCMs to Italy and assist on Tower 3 EMI taping.
We will evaluate schedule and discuss with Tracker management.
Informed
Luca that Tower B EIDP does not have mate/demate data or perhaps the link is
broken. Requested that he investigate
and also verify Tower 1 data/link.
Advised
INFN that two more Tower shipping containers have been sent to Pisa. These are for use on Tower 3 and Tower
4. Please advise when they are received
at INFN.
SLAC
reported that the Face sheet prepreg material is on schedule for a direct
shipment on 3/8 to Plyform. Jeff Tice
sent an e-mail and Sandro confirmed that the shipping address was correct. Jeff will coordinate proforma and copy
Sandro.
SLAC
reported that Tower A and Tower B are scheduled to be installed in the grid
starting (approx.) on 3/16.
Sandro
reported that he is working with Alenia to work around a schedule issue that
happens around Easter. He is proposing
that Tower 2 and Tower 3 (paired) will be the first combined Thermal Vacuum
test. He said that Tower 2 and Tower 3
would ship to Alenia on 4/15. Subsequent
Tower pairs (Towers 4 & 5, Towers 6 & 7, etc) would follow with the
test scheme. Sandro will work-up a
proposed detail schedule and forward to Tracker management for review.
Sandro
reported that seven Tower 3 MCMs were rejected at G&A. Four were successfully repaired. Three were not possible to repair. That means that we have ZERO spare MCMs.
