Power boost optimisation for the MADMAX dielectric haloscope — •Lolian Shtembari for the MADMAX collaboration — Max Planck Institute for Physics, Munich, Germany

The MADMAX experiment is aimed to directly detect dark matter axions with masses between 40μeV and 400μeV by means of a dielectric haloscope.

Such a setup promotes the conversion of axions to photons at boundaries between materials of different dielectric constants under a strong magnetic field in order to produce an electromagnetic signal.

Combining many such surfaces, the conversion and the power of the emitted signal can be significantly enhanced using constructive interference and resonances.

In the highly dimensional phase space defined by the relative position of such surfaces with respect to each other, we investigate the distribution of the power boost and we look for the largest possible enhancement by means of global optimisation algorithms.
