Overview<\/h4>\n

DLR Institute of Optical Sensor Systems (DLR) participated in the European HEMERA balloon campaign for the opportunity to measure atomic oxygen in the Earth\u2019s upper atmosphere. Atomic oxygen contributes to corrosion and deceleration of satellites in low Earth orbits and is an indicator of climate change in the upper atmosphere.<\/p>\n

DLR planned to deploy a specially designed terahertz heterodyne spectrometer, OSAS-B (Oxygen Spectrometer for Atmospheric Science from a Balloon), the first instrument of its kind to be mounted on a stratospheric balloon. OSAS-B\u2019s hot electron bolometer with a quantum cascade laser local oscillator was designed to operate in a cryostat at 4.3 K.<\/p>\n

DLR reached out to us to design the custom dewar for the OSAS-B since we had decades of experience with high-altitude cryostats.<\/p>\n<\/div>

Challenges<\/h4>\n

Many laboratory systems operate at or near sea level and at room temperature. The primary challenges of this project were related to operating in upper atmospheric conditions on a balloon gondola:<\/p>\n
