First mechanical realization of a tunable dielectric haloscope for the MADMAX axion search experiment
Abstract MADMAX, a future experiment to search for axion dark matter, is based on a novel detection concept called the dielectric haloscope. It consists of a booster composed of several dielectric disks positioned with μm precision. A prototype composed of one movable disk was built to demonstrate the mechanical feasibility of such a booster in the challenging environment of the experiment: high magnetic field to convert the axions into photons and cryogenic temperature to reduce the thermal noise. It was tested both inside a strong magnetic field up to 1.6 T and at cryogenic temperatures down to 35 K. The measurements of the velocity and positioning accuracy of the disk are shown and are found to match the MADMAX requirements.
