2. Full LAT Functional and FSW Test TCS Functional Test EMI/EMC Emissions/Susceptibility Test Limited Performance Test Comprehensive Performance Test SVAC Test F L C T S E Environmental Test Planning • LAT-MD-02717, “Environmental Test Sequence” • Been in the release cycle since early May • Updated LAT performance test info to match Per. and Ops Test Plan per Rich Baun • Every LAT perf test given a name, to correlate with P&O Test Plan • Changed NRL incoming test from CPT to LPT • Release put on hold until CPT/LPT test disagreement is resolved • Being worked in P&O Test Planning meeting Ship to NRL Baseline Rev date: 8 June 2005 C F S at SLAC Receive, Unpack Sine Vibe Mount Radiators EMI/EMC Acoustic L T L L L CS/CE RS/RE L L L L L Pre Post-Axis Pack LAT Ship to Spectrum Remove Radiators Weight CG T-Bal T-Cycle Final Pre-TV L C C S S C S L Note: electrical tests with the same label are not necessarily identical tests

3. Test Plan Status • LAT-SS-00895, “LAT Instrument Survey Plan” • Released and in-use at SLAC • May need revising to include any changes to plans for surveying at NRL • LAT-MD-01196, “LAT Dynamics Test Plan • Finalized accel placement on TKR • Ready to go, but need to go through one final clean-up pass • Updated draft ECD: 6/24 • LAT-MD-00276, “LAT EMI/EMC Test Plan” • No new info on updating EMI/EMC requirements  Michael Lovellette working on tracking down Fred Blanchette to move this forward • Updated draft ECD: 6/24 (without changes to test levels) • LAT-MD-01600, “LAT Thermal-Vacuum Test Plan • Updated test timeline • Moved bake-out to end of test • Defined test names for all LAT performance tests (e.g.: “Cold-TB LPT”) to correlate with Perf. And Ops. Test Plan • Started final update of plan • Updating MGSE/STE requirements based on new baseline thermal control plans • Updated draft ECD: 6/24

4. Current T-Vac Test Timeline (to be baselined in T-Vac Test Plan)

5. MGSE Development • Test Interface Plate • This supports the LAT for all post-integration ops (shipping, env testing), as well as Grid2 for static load testing • Requirements and interfaces finalized • Structural analysis is complete • Part drawings in release cycle • RFP is on its way to Purchasing • Assembly drawing, including assembly procedure is in review prior to release cycle • Transport Container • Being built as a turn-key design/build/test contract • Still looking at re-using an old NRL container, if we can get analysis and test data on it • Requirements and interfaces finalized • Source control drawing and statement of work are at start of release cycle (waiting for Natalie) • RFP in Purchasing at SLAC • Test Stand • Used for supporting LAT during moves at NRL, acoustic, EMI, and T-Vac tests • Requirements largely understood; interfaces for T-Vac and T-Vac STE still open until that design matures • Structural analysis started; expect completion by 6/22 • Design being updated to add features and details • Need date is late June—this is getting critical to support Pathfinder in late September • Drawing ECD: unknown

6. MGSE Development (cont.) • T-Vac Thermal STE • Sink plate and heater cages for thermally controlling LAT during T-Vac • Thermal and electrical design requirements have just been finalized • Interfaces and design concepts not well understood yet, since the mechanical requirements are not well-understood • Active design work on this has not yet started  now that the thermal requirements have stabilized, we will get a designer going on this • Drawing ECD: • This is not a schedule driver • Remaining MGSE/STE hardware design has generally not yet started: none are schedule drivers, all are relative small and discrete, and all are being used as fill-in work • SC Top Deck acoustic simulator—not started • Radiator SC Strut simulator—waiting on SC strut design info • Spreader Bars—design started • Test MLI blankets—waiting completion of flight blanket design

7. EGSE Development and Networking • T-Vac cabling • Cable pin-outs and schematics have been finalized • Feedthroughs have been ordered • Internal cable routing/lengths being finalized now • Internal cable drawings have been started (ECD: ) • External cable drawings not yet started (ECD: ) • EMI cabling • Cable routing is waiting on EMI cell layout drawing completion • This cabling will also be used for acoustic, sine vibe, and high-bay testing • Mobile Computing Rack • Final architecture not yet worked out—needed at SLAC before LAT CPT ~Nov • Many parts not purchased yet—firewall and router ordered, with ETA in early November • Issue is priority with other work • Networking • Env testing at NRL • No MOU paper yet from NRL  need pressure applied to keep this moving • Observatory I&T at Spectrum • Network planning just starting • Lots of details to work, but need a contact at Spectrum to work with (Brian is working this)

8. Facilities, Operations, and Logistics • NRL facility drawing status • Sine vibe table LAT-DS-5905-01 complete 4/20/2005 (rev in progress) • Slip table LAT-DS-5903-01 complete 5/2/2005 • Expander head LAT-DS-5904-02 complete4/25/2005 • High-bay tent LAT-DS-5899-01 complete 4/20/2005 • Vibe facility LAT-DS-5902-01 in release cycle at NRL • Acoustic facility LAT-DS-5906-01 in release cycle at NRL • T-Vac facility LAT-DS-5907-01 complete 4/20/2005 (rev in progress) • EMI facility LAT-DS-xxxxx ECD: 6/21/2005 • A-59 west high-bay LAT-DS-xxxxx ECD: 7/15/2005 • Key issues being worked at NRL (Bill Raynor) • Trestle bridge load certification • T-Vac trolley retrofit/load test—waiting LAT footprint from SLAC • How to move LAT into and out of T-Vac chamber

9. Observatory I&T Planning • LAT-MD-06560, “Plan for Integrating and Testing the LAT on the Observatory” • Significantly redlined at Spectrum in late May • Redlines being incorporated into an updated draft • Once this is finalized, LAT will release it and Spectrum will add it to a new appendix of the ICD • Intent is to capture all issues regarding Obs I&T that either affect us or that we have requirements for
