Axion dark matter searches using superconducting radio frequency cavities — •Tom Krokotsch1, Robin Löwenberg1, Daniel Klein1, Gudrid Moortgat-Pick1,2, and Krisztian Peters2 — 1Universität Hamburg, Hamburg, Germany — 2Deutsches Elektronen-Synchrotron DESY, Hamburg, Germany
Recent proposals of employing superconducting radio frequency (SRF) cavities to detect axions suggest promising sensitivities in previously unexplored parameter space. This includes QCD axions and axion-like dark matter with masses in a range of about eight orders of magnitude.
The setup aims to detect photons generated through the predicted interaction of axions with electromagnetic fields. An advantage of this design is that it allows scanning over a range of axion masses by slightly altering the cavity. Such a detector benefits from the high quality factors achieved in modern SRF technology.
In the talk we discuss the general idea behind the detector, it's most significant parameters to achieve a high signal power and evaluate which cavity geometries and transitions are the most promising. Particular attention must be paid to minimise various noise sources which limit the sensitivity of the setup.
