Searching for Axion Like Particles with the MADMAX prototype

The MADMAX experiment proposes to search for QCD dark matter axion in the range 40-400 $\mu$eV using the novel dielectric haloscope concept. In order to validate this technique a prototype will be build and needs to be tested in a large bore dipole magnet. The CERN Morpurgo magnet, currently available in EHN1 and operated by ATLAS for its test beam on the H8 line, could be used for that purpose. The period of interest will be during the SPS shutdowns in the period 2022-2024. In addition to the prototype validation, one month of operation in the MORPURGO magnet will allow to probe an unexplored region of the ALP and dark photon phase spaces.
