AB  - This contribution presents distributed and multipoint fiber-optic monitoring of 
      cryogenic temperatures along a superconducting power transmission line down to 30 
      K and over 20 m distance. Multipoint measurements were conducted using fiber 
      Bragg gratings sensors coated with two different functional overlays (epoxy and 
      poly methyl methacrylate (PMMA)) demonstrating cryogenic operation in the range 
      300-4.2 K. Distributed measurements exploited optical frequency-domain 
      reflectometry to analyze the Rayleigh scattering along two concatenated fibers 
      with different coatings (acrylate and polyimide). The integrated system has been 
      placed along the 20 m long cryostat of a superconducting power transmission line, 
      which is currently being tested at the European Organization for Nuclear Research 
      (CERN). Cool-down events from 300-30 K have been successfully measured in space 
      and time, confirming the viability of these approaches to the monitoring of 
      cryogenic temperatures along a superconducting transmission line.
