Abstract
Temperature sensitive glassware has been developed to monitor liquid chemical temperature in a microwave environment. A combination of two phosphor powders is coated to the base of a Pyrex beaker & Quartz tube, which fluoresce under blue light stimulation. These temperature sensitive glassware monitors changes in liquid or surface temperature by observing ratios of peak emission intensities of the phosphors. The temperature sensitive Pyrex beaker is placed on an oven so that surface temperature can be accurately monitored. A fabricated coated Quartz tube is placed in an Industrial Free Electron Laser (IFEL), which provides the necessary microwave radiation to heat liquids and therefore provide liquid measurements. This paper describes the testing of the coating and its application in monitoring liquid temperature in an Industrial Free Electron Laser.
