AbstractIn this paper, the blackbody radiation (BBR) temperature rise experienced by a Ca-40(+) ion confined in a miniature Paul trap and its uncertainty have been evaluated via finite-element method (EhM) modelling. The ELM model was validated through comparisons with thermal camera measurements at several points on a dummy trap. Before the validation, the thermal camera was calibrated by using a PT1000 resistance thermometer. The input modelling parameters were analyzed carefully, and their contributions to the uncertainty of the trap environment temperature were evaluated using the validated ELM model. The result shows that the temperature rise experienced by the Ca-40(+) ion is 1.72 K with an uncertainty of 0.46 K. It results in a contribution of 2.2 mHz to the systematic uncertainty of a Ca-40(+) ion optical clock, corresponding to a fractional uncertainty 5.4 x 10(-18). This is much smaller than the uncertainty caused by the BBR shift coefficient, which is evaluated to be 4.8 mHz and at the 10(-17) level in fractional frequency units.
