N2 - An experimental facility has been created at the BINP SB RAS for simulating pulsed thermal loads using a laser pulse of submillisecond duration. Tungsten was used as the test sample material, for which the surface temperature was determined by pyrometry. The main factors affecting the temperature measurement accuracy by this method are that there is a need to take into account the surface roughness of the samples and the literature contains different emissivity data, which are not consistent with each other. However, the results of theoretical simulation showed these factors have little effect on pyrometry accuracy. Based on the thermophysical data of tungsten and the parameters of the laser pulse, the temporal dynamics of the tungsten surface temperature during thermal shock was simulated. The obtained experimental data are consistent with theoretical simulation.
