Abstract
Precise temperature monitoring —to the level of a few milli-Kelvin— is essential for the operation of large-scale cryostats requiring a recirculation system. In particular, the performance of Liquid Argon Time Projection Chambers —such as those planned for the DUNE experiment— strongly relies on proper argon purification and mixing, which can be characterized by a sufficiently dense grid of high-precision temperature probes. In this article, we present a novel technique for the cross-calibration of Resistance Temperature Detectors in cryogenic liquids, developed as part of the temperature monitoring system for a DUNE prototype. This calibration has enabled the validation and optimization of the system’s components, achieving an unprecedented precision of 2.5 mK.
