Vibration Decoupling System for the NUCLEUS Experiment — •Alexander Wex, Raimund Strauß, Johannes Rothe, Luca Pattavina, Nicole Schermer, Andreas Erhart, Tobias Ortmann, Victoria Wagner, and Margarita Kaznacheeva — Technische Universität München, Physik Department Lehrstuhl E15, James-Franck-Straße 1, D-85748 Garching

The coherent neutrino nucleus scattering experiment NUCLEUS deploys a new-generation dry dilution refrigerator. Vibrations induced by the cryostat's pulse tube cooler are a challenge for stable detector operation. To achieve detector performance undisturbed by pulse tube operation, a dedicated spring-decoupling system is being developed for NUCLEUS. Recent results and benchmark measurements for the design of this cryogenic vibration decoupling system are presented. The research was supported by the DFG through the Excellence Cluster ORIGINS and the SFB1258, and the ERC Starting Grant 2018 "NU-CLEUS".
