| الوصف: | Performance of any sensor in a nuclear reactor involves reliable operation under a harsh environment (i.e., high temperature, neutron irradiation, and a high dose of ionizing radiation). In this environment, accurate and continuous monitoring of temperature is critical for the reactor's stability and proper functionality. Furthermore, during the development and testing stages of new materials and structural components for these systems, it is imperative to collect in-situ measurement data about the exact test conditions for real-time analysis of their performance. To meet the compelling need of such sensing devices, we propose radiation-hard temperature sensors based on the phase change phenomenon of chalcogenide glasses. The primary goal is to resolve the monitoring of the cladding temperature of light water and metallic or ceramic sodium-cooled fast reactors within a temperature range of 400°C to 600°C. This work is focused on studies of Ge-Se(S) chalcogenide glasses that have crystallization temperatures in this range. Each chalcogenide glass transforms and becomes crystalline at a specific heating rate at a definite temperature. As a result of this, both the electrical resistance and optical properties of the materials change. As this is the first time such devices have been fabricated, this work submits new data regarding materials research, various device structures, fabrication, performance, and testing under irradiation. The application of these materials in devices usually involves the formation of a thin film that works as an active layer. Traditionally, thin films are prepared by thermal evaporation, sputtering or chemical vapor deposition and they require high vacuum machinery and patterning applying photolithography. To avoid using such heavy machinery and costly fabrication processes, we investigate the formulation of nanoparticle inks of chalcogenide glasses, the formation of printed thin films using the inks, low-cost sintering and demonstrate their application in electronic and photonic sensors ... |
