Current Situation
SLAC
LAT Meeting
17Jul 2003
Absorption of original French Work
 Revised MoA with IN2P3 has been signed.
 Drawings have been translated to English. Most are ready for release. Critical
titanium parts are in manuf.
 Side plates will be purchased from France
 Baseplate delayed in CAL-Grid I/F redesign and assoc analyses
 CDE bonding team in place at Swales. Test bonding has begun. Flight qual
tooling is being manufactured.
 PDA manufacturing tooling in design, process specification is being updated.
Requirements have been discussed with potential vendors. RFQ has not been
released

ASIC GCFE ver 9A has been submitted. Out of fab 9/17/03
 GCRC5 working on EM w/ GCFE7 does not work well at 20 MHz. Problems
are being investigated
 EM EMI/EMC testing indicate need for better test configuration and test
plans. Don’t know if they show design problem in CAL.

Interdependencies with other
GLAST Calorimeter
LAT components

SLAC
LAT Meeting
17Jul 2003
Resolve and verify CAL – Grid interface
 Complete analyses. Detail extra features – cable tray attachment
 Release IDDs or whatever


Resolve and verify CAL – T&DF box mechanical, thermal design,
and EMI/EMC design.
Identify, cost and schedule needed TEM and PS (EM2??) that
supports the compressed CAL assembly and test schedule.
 Improve documentation and procedures

Produce EEE Parts required documentation (as identified by
GSFC) for the ASICs or tell them NO and resolve the qualification
of the ASICs for flight.

Flight Hardware
Procurements
Except for new work in US, most flight procurements are made or are in
process.
 EEE parts complete except for uncertainty on some PPL resistors.
 AFEE – TEM interconnect cable order needs design verification and EEE parts
test agreement.
 AFEE PCB is in design modification.

CDE manufacturing contract in place – Swales
 PDA manufacturing spec is in development – outside vendor, GFE’ed to
Swales.
 Plan CDE Manufacturing Readiness Review in August.

Metallic machined parts from NRL.
 Awaiting revised drawings of baseplate.
 Potential issues relative to recent EMI/EMC testing – surface treatment, more
screws

Plastic and Elastomeric parts for CDE – structure interface at LLR
 Specs in place, vendors selected, parts approved.
 First procurements in place.

ASIC acceptability for flight – both performance and
qualification.
CDE Bonding process development and qualification
delay.
Ability of Sweden to maintain the delivery rate and
schedule of CsI crystals.
EEE parts use approval and impact on assembly of
AFEE board.
Failure or process problem in module assembly or test
which stops the production pipeline.

SLAC
LAT Meeting
17Jul 2003
CAL will receive 18 Flight TEM and Power Supplies that are fully tested and ready
for integration with CAL flight hardware.



Required EGSE for functional testing of TKR side of TEM will be provided.
Required Test scripts for testing of TKR side of TEM will be provided.
TKR simulation configuration (whatever is required) will meet environmental test
requirements – TVAC, EMI/EMC(?), Vib
–
–


mechanical support of connector savers during vib?
Cable lengths or mounting of simulators
Capable of surviving CAL Vibration Test levels
Capable of providing appropriate EMI/EMC test environment.

~5 EM1 or EM2 TEM boards (unpackaged?) to support AFEE card assembly and
test
 CAL will receive sufficient VME Interface Cards (COMM & PDU?) and PowerPCs to
support XX CAL Test Stands



10 CTS to support module Assy & Test
6 mini CTS to support AFEE card assembly and test - minimal config, power control not
needed.
EGSE communications (COMM to/from TEM) can support required cable lengths
for TVAC and EMI/EMC testing over temperature – 10 m or more with bulkhead
connector adaptors.
