000587798 520__ $$aBefore the successful detection of gravitational waves (GWs) with LIGO and VIRGO, superconductingradio frequency (SCRF) cavities were already considered as potential alternativesfor large laser interferometers. They are particularly suited to probe high frequencies above∼ 10 kHz by using a heterodyne approach where the GW has to be resonant with the frequencydifference of two cavity eigenmodes. Since DESY/UHH and FNAL intend to reactivatethe research on these detectors, this thesis revisits the theory of the GW-detector interaction.In this context, we consider the indirect coupling to the cavity boundaries as well as the directcoupling to the electromagnetic field mediated by the Gertsenshtein effect. The formalismis applied to the geometry of the MAGO prototype, which was built in 2005 at INFN inGenoa.We compare the results with recent publications that focus on the same type of detectors.Different to these papers, we include a damping term that was initially found by Bernard et al. (2002) and significantlyflattens the Breit-Wigner curves of the resonances. We further provide a detailed analysisof the mechanical coupling as well as possible noise sources and the prospective sensitivity ofthe MAGO cavity. The results are compared to signals above 10 kHz from promising candidatesfor new physics, including primordial black holes (PBHs) and black hole superradiance. Weshow that future improvements of the MAGO parameters could enable to reach the region ofnew physics. The aim of this thesis therefore is to provide a basis for future research on thetheoretical as well as experimental aspects of the detector, focusing on possible modifications.
