The thermal contact conductance (TCC) of a real front‐end component at SPring‐8 has been quantitatively estimated by comparing the results of experiments with those of finite‐element analyses. In this paper one of the methods of predicting the TCC of a real instrument is presented. A metal filter assembly, which is an indirect‐cooling instrument, was selected for the estimation of the TCC. The temperature of the metal filter assembly for the maximum heat load of synchrotron radiation was calculated from the TCC that is expected under normal conditions. This study contributes towards the ongoing research program being conducted to investigate the real thermal limitation of all front‐end high‐heat‐load components.
