Abstract

A technique for infrared thermometry remote monitoring of temperature of area of a polymer film under ion irradiation is described. Calculation part of the technique takes into account the case when the irradiated area is significantly smaller than the instrument field of view. Temperature measurements were carried out with 20 μm polyimide films irradiated by 1000 to 1600 keV protons, with 1…5 μA/cm2 current density. A model for calculation of temperature depth distribution in the irradiated film is developed. The model is also applicable for the case of ion irradiation in gaseous atmosphere, and takes into account temperature dependence of the polymer substance thermal conductivity, of the emissivity coefficient, and of the convective heat transfer coefficient. The calculated data are compared with the temperature measurements.
