    摘要： An optical gamma thermometer includes a metal mass having a temperature proportional to a gamma flux within a core of a nuclear reactor, and an optical fiber cable for measuring the temperature of the heated metal mass. The temperature of the heated mass may be measured by using one or more fiber grating structures and/or by using scattering techniques, such as Raman, Brillouin, and the like. The optical gamma thermometer may be used in conjunction with a conventional reactor heat balance to calibrate the local power range monitors over their useful in-service life. The optical gamma thermometer occupies much less space within the in-core instrument tube and costs much less than the conventional gamma thermometer.

    摘要： A system for analyzing gas concentrations in a gas mixture includes an array of semiconductor light sources which are configured to generate an electromagnetic radiation having a narrow bandwidth. A controller modulates the electromagnetic radiation at a modulating frequency to provide light pulses at an absorption wavelength of at least one target gas. The system also includes an acoustic resonant gas chamber to hold the gas mixture and configured to receive the light pulses and amplify acoustic signals emanating from the gas mixture. A processor determines a concentration of the target gas based on acoustic signals.
