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

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 Baseline Ship to NRL Rev date: 8 June 2005 C F S at SLAC Receive, Unpack Sine Vibe Mount Radiators EMI/EMC Acoustic L T L L L L CS/CE L RS/RE L L L Pre Post-Axis Pre-TV T-Bal T-Cycle Final Remove Radiators Weight CG Pack LAT Ship to Spectrum C S L S L C C S L Limited Performance Test Comprehensive Performance Test SVAC Test C S F T E Full LAT Functional and FSW Test TCS Functional Test EMI/EMC Emissions/Susceptibility Test Note: electrical tests with the same label are not necessarily identical tests

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

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

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

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

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)

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

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
