Understanding the RF response of the MADMAX experiment — •Juan Pablo Arcila Maldonado for the MADMAX collaboration — Max Planck Institute for Physics/ University of Bonn

The MADMAX collaboration aims to probe the parameter space of the QCD axion around the well-motivated range of 40-400 µeV, which is out of reach for conventional cavities, using a novel technique referred to as dielectric haloscope. This concept relies on the power enhancement by constructive interference of axion-induced microwave signals from multiple dielectric boundaries. A prototype to verify the sensitivity of this approach was built, which helped to understand the underlying physics and the dependency from parameters on the axion-generated signal power. This talk presents the first results and discusses the next steps toward a possible final MADMAX setup.
