Cryogenic Thermometry System

The team of MicroXact, Inc., JLab and Virginia Tech is developing a distributing fiber optic temperature mapping solution for Superconductive RF (SRF) cavity characterization. The solution will provide accurate, fast, reliable, EMI and radiation immune temperature mapping of superconducting cavities with very high sensor density, low cost per sensing point and ease of calibration, installation and use.

The findings during the project resulted in both improved understanding of thermal expansion of a number of nanomaterials and nanocomposites and in demonstration of temperature sensitivity of fiber Bragg grating temperature sensors at six (6) times lower temperature than previously reported. The nanocomposite materials developed by MicroXact offer unprecedented control over thermal expansion.
