Power Calibration of a Dielectric Haloscope — •Bernardo Ary dos Santos for the MADMAX collaboration — RWTH, Aachen, Germany

The MADMAX collaboration intends to build a dielectric haloscope targeted to detect galactic axion dark matter, in the mass range from 40 to 400 μeV . This experiment consists of a series of dielectric discs and a mirror placed inside a strong homogeneous magnetic field that would produce the emission of coherent electromagnetic radiation with a frequency related to the mass of the axion. A prototype has recently been tested at CERN inside a 1.6T dipole magnet. In this talk I will explain the Power calibration procedure used during the data taking that allows us to estimate the sensitivity of the experiment.
