Abstract
We have developed thermal impulse sensors to measure and record temperature and heating duration in explosive fireballs. The functionality of these sensors is similar to that of our temperature-only sensors – rare-earth ions are used to monitor temperature-induced phase changes. However, in this case two sensor materials, p-Dy:Y2O3 and p-Eu:ZrO2, with different phase change kinetics are mixed. In addition, a fluorescence standard, Ho:ZrO2, is included. Also, using laser heating, we have now reduced the shortest heating duration for our calibration measurements from the previously reported 2 s to 100 ms, and we have evaluated these sensors for temperatures between 400 °C and 900 °C, and heating times between 100 ms and 1000 ms. Using spectral matching, we determine the temperature and heating duration.
