Strain Measurement in the Spallation Target Using High-Radiation-Tolerant Fiber Sensors
IEEE Sensors Journal(2018)
摘要
We describe the measurement of fast dynamic strains in the mercury target module of the spallation neutron source using customized high-radiation-tolerant fiber-optic strain sensors. The sensors are made from fluorine-doped single-mode optical fibers that demonstrated high radiation tolerance at 1300 nm. A digital phase demodulation scheme is employed in the signal interrogation system, which enab...
