LAT Status

  • LAT completed commissioning at SLAC May 10th.

    • Determined effort by the Commissioner: Eric Grove

    • Excellent support leadership from

      • System Engineering: Pat Hascall

      • Electronics/ FSW: Gunther Haller

      • I&T OnLine: Ric Claus

      • OffLine: Anders Borgland

  • Packed up on May 11th and departed by dedicated truck (photos to follow)

  • Arrived NRL on Sunday, May 14th and installed in clean tent. MGSE and EGSE arrived on Tuesday, May 16th.

  • Up and running by Wednesday, completed post ship comprehensive performance test on Friday.

  • Continued calibrations and additional tests thru the weekend.

  • Installed new flight software and completed regression tests by Wednesday

  • Successfully completed Pre Environmental Review with GSFC on Thursday.

  • Moved to Vibration Test Lab on Friday. Vibe testing began yesterday.

Conclusion
Conclusion

  • The LAT is complete and tested.

    • No significant anomalies detected to date, except

      • Radiator heaters were damaged during assembly process and are now being replaced

    • No performance anomalies detected. Trending shows same instrument throughout assembly and test program.

  • The LAT Flight Software is essentially complete.

    • Missing GRB detection algorithm and event filter additions

      • Neither particularly relevant for ground testing.

      • Development will continue on the test bed at SLAC.

  • New OnLine operating system – LICOS – commissioned

  • The LAT project has successfully transferred activities (and people) to NRL and is efficiently executing its environmental test program.
