Axion search with RADES — •Elisa Gabbrielli for the RADES MPP collaboration — Max Planck für Physik, Munich

RADES (Relic Axion Detection Exploratory Setup) is a haloscope experiment designed to search for axions originating from the local dark matter galactic halo in the μeV mass range, under the assumption that dark matter is entirely composed of axions. The detection technique relies on a resonant cavity placed inside a strong magnetic field, which enhances the conversion of axions into detectable photons. The collaboration has achieved significant progress regarding the development of new cavity geometries, leading to two physics results at axion masses around 30 μeV.

An innovative RADES setup incorporating transmon qubits is currently being developed within the collaboration. This talk focuses on the activities at the Max Planck Institut für Physik in Garching. To maximise the signal-to-noise ratio, the experiment operates at cryogenic temperatures using a dilution refrigerator that can reach approximately 10 mK. At these extremely low temperatures, superconducting devices such as transmon qubits can be employed as single-photon detectors to further improve signal sensitivity.
