Description
The MADMAX experiment aims to search for dark matter axions in the frequency range 10-100 GHz using a configuration where large thin dielectric disks are stacked in parallel under a strong magnetic field.
When searching for a narrow signal using a large bandwidth, data acquisition plays a critical role. Here we describe a data acquisition system based on a spectrum analyzer. In addition we present the power calibration, and another important component of the experiment where the signal amplification factor (boost factor) is deduced using the bead-pull method [1] in an open booster system.
