Description
The nature of dark matter is one of the biggest open questions in physics today.
One possible answer is the axion, which was originally predicted as a solution
to the strong CP problem but also makes for an excellent cold dark matter can-
didate. The MAgnetized Disk and Mirror Axion eXperiment (MADMAX) aims
at detecting axions from the galactic dark matter halo in the theoretically well
motivated mass range around 100 µeV using a dielectric haloscope. It utilizes
a booster system consisting of a stack of dielectric disks and a mirror to reso-
nantly enhance the axion-photon conversion in a magnetic field. This approach
is designed to overcome sensitivity limitations of conventional cavities at axion
masses above ∼50 µeV. The detector concept and how it is calibrated is ex-
plained and recent results of a dark photon and an axion search are presented.
Future plans will also be discussed.
