Minutes from October 1999 EXES Meeting

Link to the glossary

John, Dan, Mary Kay, Tommy, and Matt attending

Mechanical:
Dewar design is basically done. Drafting is not close (no estimate of when) because many details need to be added.
May have FAA drawing package available for Critical Airworthiness Design Review by mid-Nov. Analysis on about the same time scale. FAA report must include:

Estimate earliest possible complete report would be Jan. This puts dewar arrival at end of summer 00, which isn't much use.
Mechanical slip is not deadly since software and electronics would be debugged instead.

Electronics:
All cabling except chip socket is complete. Chip sockets should be done by end of the month. Testing of cables scheduled for next week.
Detector bare readout hasn't arrived. Wallace hasn't provided clocking patterns for readout yet. Need to have an estimate of integration times for various modes and wavelengths at McDonald.
Digital logic for sending clocking patterns is understood.

Software:
Detail software plan for minimum system still not done. Wallace software still being studied. McDonald has been alerted to our need for help.
ADC board requirements have been studied. Checking on availability of Linux RedHat 6.0 drivers from supplier.

Proposals:
Wrote 4 proposals asking for 12 nights (4 nights engineering time; 4 nights circumstellar shells; 2 nights M82; 2 nights stellar magnetic fields).

SSSC Meeting:
Summary of relevant topics at SSSC includes: Expect 0.8" rms pointing at start of operations (with the Flexible Body Compensation in operation). The tertiary will likely be supported with struts to improve pointing. First science flight scheduled for Nov 2002. NASA dignitaries visiting Waco on Nov 3; EXES science team members encouraged to attend.

Action Items:
Mary Kay:

  • Organize next EPO meeting agenda.

    Matt:

  • Contact vendors regarding ADC board drivers.
  • Work on FAA Functional Hazard Analysis.
  • Come up with Documentation scheme.
  • Finish plans for software programs.

    John:

  • Find out when bare readout should arrive.
  • Work on Continued Airworthiness and Maintenance Manual.
  • Assist Frank Ray in FAA analysis.

    Dan:

  • Contact Wallace about communications board and EPROMs.
  • Check out wiring.
  • Check out electronics system.
  • Estimate integration times for various resolutions, wavelengths.

    Tommy:

  • Check out wiring.
  • Check out electronics.
