Paper Abstract

A unique flexural pivot mirror translation system was used in the fabrication of a cryogenic Michelson interferometer spectrometer. Uniform cooling was obtained by placing the interferometer inside a convective atmosphere within a liquid nitrogen dewar. The interferometer was flown as part of the EXCEDE SPECTRAL rocket payload which also included electron accelerators to produce artificial auroras. The interferometer successfully measured infrared upper-atmospheric emissions within the spectral range 2.0 to 5.6 μm as induced by the pulsed electron accelerators. Observed emissions include the N2 Wu Benesch infrared system, the N2 McFarlane infrared system and CO2. In addition, H2O outgassing from the payload was observed. The 2 cm-1 spectral resolution of the interferometer clearly assisted in the unique identification of the dominant emissions based on their characteristic molecular band profiles.
