SUPAX - A Superconducting Axion Search Experiment — •Tim Schneemann, Kristof Schmieden, and Matthias Schott — Johannes Gutenberg-Universität, Mainz

Supax is one of the first RF cavity based experiments in Germany to search for axions. Axions are hypothetical particles that could solve the well known strong CP problem in the standard model of particle physics. Furthermore axions could explain the dark matter content of the universe. Axions are expected to convert to photons in the presence of a strong magnetic field, where the photon frequency depends on the axions mass. For wavelengths in the microwave regime resonators are typically used to enhance the axion signal. We propose to use a superconducting radio frequency cavity with high quality factor. A Copper RF cavity has already been successfully tested probing for Dark Photons in the absence of a magnetic field whilst tune-able and superconducting RF cavities are currently being developed. With this innovative approach and by using an existing 14T magnet at the Institute of Physics at the Johannes Gutenberg University in Mainz, the largely unexplored mass region between 20 µeV to 50 µeV could be tested.

In this talk I will cover the experimental setup, data acquisition, analysis and current results of the experiment as well as future ideas of the experiment beside the search for axions.
