June 14: Monitor Stability w/Room Temperature Change

• Configuration:

  • ACS: Fully Assembled
  • Mounting: In Dolly, in Square with Radiator Facing Up & Parallel to Floor
  • Cooling: Chillers
  • Optical Source: HRC Coronagraph Backlight
  • Starting Temp: Ambient at Start of Day

• Figures:

  • Stability track: ( GIF, Postscript )

• Results:

  • "Warm-up" and/or Chiller Effect seen for ~4 Hours at Start of Day
  • Stability after 1700GMT Correlates with JO3APANT Enclosure Panel Temperature & Enclosure Panel Correlates Grossly with Room Temperature

• Conclusion

  • Stability is Correlated with Room Temperature
  • Potential Mechanism is Dolly Length Change with Temperature Loads Enclosure
