Cryogenic distributed temperature monitoring (Cryo-DSS)

The purpose of the Phase II SBIR research project is to demonstrate multiplexed, high speed, accurate distributed cryogenic temperature measurements made through cryogenic quick disconnects. In order to achieve this, several fiber variations will be tested to determine optimal sensitivity at cryogenic temperatures. It is expected that robust and well understood algorithms will be improved and tested to extend Rayleigh Backscatter calculations over 100 meter lengths of fiber. The electronic readout system speed will be increased to enable multiplexing of 48 channels of data each interrogating a 100 meter sensor. Integration of the fiber into an OEM degaussing cable will significantly increase the TRL of the system and bring Luna’s technology closer to market.
