Abstract

An optical fiber-based gamma thermometer (OFBGT) was calibrated as a precursor to its testing in the Ohio State University Research Reactor (OSURR). Modeling of the OFBGT predicts that the OFBGT responds like a first order system to step changes in heating with a nichrome wire. That prediction is verified by experiment. The predicted OFBGT steady-state response and response time are less than their corresponding measured values by about 15%. Nevertheless, the agreement between modeling and measurements is sufficiently good to conclude that the OFBGT sensor has been constructed correctly and that the principles of its operation are well-understood.
