英文摘要	The sensitivity of distributed temperature sensor system based on Raman scatterings was discussed and experimentally characterised under mechanical loading, cooling down to 77 K and magnetic field. Several hundreds of meters Fibre-based distributed.is achieved with high spatial and temperature resolutions by using a correlation-coding under cryogenic temperature. The results indicate that distributed temperature sensor with soft polymeric coating fiber based on Raman scatterings can detect distributed cryogenic temperature, their accuracy and repeatability are also discussed in detail. At variable magnetic field or loading field, the tested results show that fibre-based distributed temperature sensor considering suitable substrate and structure is unaffected, there are no the magnetic and mechanical effects for the distributed temperature sensor under cryogenic temperature. The present results are expected to be able to provide basis detection on the distributed temperature for excited high temperature superconducting (HTS) magnets/cables, independently or utilized together with other measurement methods.
