Photothermal radiometry measurement of thermophysical property change of an ion-irradiated sample

Highlights: ► Ion-irradiated sample measured using photothermal radiometry. ► Results agree with other examinations. ► PTR is demonstrated to be useful for post-irradiation examination. ► Many applications exist in the nuclear community. - Abstract: Using photothermal radiometry (PTR) an ion-irradiated ZrC sample's thermal properties are measured by fitting frequency-scan data to a theoretical model for the surface temperature. The technique is shown to measure thermal properties without physical contact of a very small sample.
