1. Environmental Test Planning
LAT Face-to-Face Manager’s Meeting
15 June 2005
Environmental Test Planning
Martin Nordby Neil Johnson

2. 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

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

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
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)

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
