First measurements with a MADMAX 8 disk prototype booster system for the search of dark matter — •Umashi Fernando for the MADMAX collaboration — Max-Planck-Institut für Physik, Boltzmannstr. 8, 85748 Garching

The main aim of the MADMAX experiment (Magnetised Disc and Mirror Axion Experiment) is to search for the hypothetical particle that solves the strong CP problem and is also an excellent cold dark matter candidate: the axion. The electric field oscillations due to axion conversion to photons in the presence of a strong magnetic field can be detected, but the signal is very weak. Thus, a configuration with dielectric disks in front of a mirror is used to resonantly enhance the signal over a controllable frequency range.

In this talk, measurements taken with an 8-disk closed prototype booster system CB200 will be discussed. Some details of the used receiver chain and data acquisition system will be given.

Keywords: dark matter detection; axion; receiver chain
