Abstract : This report details the design of the liquid nitrogen dewar to be used as a cryogenic enclosure for a cryogenic interferometer. The total package, including the cryogenic enclosure and the interferometer, will be balloon borne to an altitude of approximately 80,000 feet. Thus the system must be designed and built to withstand the rigors of launch and the changing environment resulting from ascent and descent. This would primarily include changes in temperature and atmospheric pressure. When the system reaches altitude the interferometer will take data in the 4 to 14 micron region. This data will be telemetered to ground for future analysis. Other experiments are also anticipated such as determining certain atmospheric constituents as a function of altitude.
