Aria is designed to purify the argon, extracted from underground wells in Colorado, USA, and used as the DarkSide-20k target material, to detector-grade quality. In this paper, we report the first measurement of argon isotopic separation by distillation with the 26m tall Aria prototype. We discuss the measurement of the operating parameters of the column and the observation of the simultaneous separation of the three stable argon isotopes: <sup>36</sup>Ar, <sup>38</sup>Ar, and <sup>40</sup>Ar. We also provide a detailed comparison of the experimental results with commercial process simulation software. This measurement of isotopic separation of argon is a significant achievement for the project, building on the success of the initial demonstration of isotopic separation of nitrogen using the same equipment in 2019.application/pdfenCreative Commons Attribution 4.0 InternationalMeasurement of isotopic separation of argon with the prototype of the cryogenic distillation plant Aria for dark matter searchesArticle - Refereed2023-06-04The Author(s)The European Physical Journal Chttps://doi.org/10.1140/epjc/s10052-023-11430-0
