Description
The MADMAX experiment is aimed to directly detect dark matter axions
with masses between $40\,\mu{\rm eV}$ and $400\,\mu{\rm eV}$ by using
their conversion to photons at boundaries between materials of different
dielectric constants under a strong magnetic field. Combining many such
surfaces, this conversion can be significantly enhanced using
constructive interference and resonances. We present a first
proof-of-principle realization of such a booster system consisting of a
copper mirror and up to 5 sapphire disks. The electromagnetic response
of the system is investigated by reflectivity measurements. The
mechanical accuracy, calibration process of unwanted reflections and the
repeatability of the results using basic optimization algorithms to
place the disks are investigated. Possible systematics from 3D effects
such as tilts are discussed. We find that for the presented cases the
electromagnetic response predicted by previous one-dimensional
theoretical calculations is sufficiently realized with our setup.
