Demonstrating Electromagnetic Properties of a MADMAX prototype booster — •Jacob Egge for the MADMAX collaboration — Max-Planck-Institut für Physik

Axions are a promising candidate for dark matter. The Magnetized Disc and Mirror Axion Experiment (MADMAX) uses dielectric discs to boost axion to photon conversion by the Primakoff-effect. A small scale prototype for the MADMAX experiment is being developed. The purpose of this setup is to demonstrate the ability to understand the electromagnetic properties of a future dielectric haloscope with a given boost factor. This is done by arranging 20 saphire discs with micrometer precision motors in different configurations and measuring reflections of microwaves with a vector network analyzer. By comparing the electromagnetic properties with simulations a boost factor can be inferred. We will present the latest results of this ongoing process with emphasis on the procedure used to optimize discs arrangements.
