An FBG Optical Approach to Thermal Expansion Measurements under Hydrostatic Pressure

An FBG Optical Approach to Thermal Expansion Measurements under Hydrostatic Pressure

We report on an optical technique for measuring thermal expansion and magnetostriction at cryogenic temperatures and under applied hydrostatic pressures of 2.0 GPa. Optical fiber Bragg gratings inside a clamp-type pressure chamber are used to measure the strain in a millimeter-sized sample of CeRhIn...
