Current SituationCurrent Situation

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 Interdependencies with other LAT componentsLAT components

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 Flight Hardware ProcurementsProcurements

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.

Greatest Risks to ScheduleGreatest Risks to Schedule

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.

Unresolved AssumptionsUnresolved Assumptions

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.
