Abstract

Experimental results of the campaign to determine a method for measuring the temperature of a surface exposed to the highly concentrated radiation at HoSIERthrough three different conditions: quartz window, PYREX® window and without window are presented in this paper. It seeks to achieve a method for measuring the surface temperature without any thermocouple contact, preventing its overestimation due to the effect of the surface's radiosity itself.This methodology is able to determine a correction factor of the emissivity (FCε) depending on the incident temperature. In addition to determine the temperature difference overestimated due to the component of the radiation reflected by the surface.
