21. The MAGO cavity and prospects for HFGW searches

Krisztian Peters (Deutsches Elektronen-Synchrotron (DE))

The former MAGO collaboration, led by INFN Genoa, developed in the past SRF cavities in order to perform R&D with the aim to search for gravitational waves. In a collaborative effort, DESY/U.Hamburg and Fermilab continues this R&D programme. Since July the MAGO cavity is at DESY for measurements and matching simulations to characterise the cavity before surface treatment and cold measurements...

18. Searching for Axions and High-Frequency Gravitational Waves with ABRACADABRA-10cm

ABRACADABRA-10cm has had great success as a lumped-element axion dark matter pathfinder experiment. Now, using the electrodynamics of gravitational waves and a simple change of pickup structures, we are using the ABRACADABRA detector to search for high-frequency gravitational wave in the kHz to MHz range. These higher frequencies may indicate signs of in-spiraling primordial black holes, or...

1. Prospects for HFGW searches with the axion experiments ALPS II and BabyIAXO

Axel Lindner

At DESY in Hamburg, axions search experiments not relying on the dark matter paradigm are taking data (ALPS II) or have good prospects to start construction soon (BabyIAXO). Due to the similarity of axion-photon and GW-photon conversions in background magnetic fields, both experiments will also be sensitive to high frequency gravitational waves (HF-GW). The status of ALPS II and BabyIAXO as...

17. Detection of high-frequency gravitational waves using high-energy pulsed lasers

Georgios Vacalis

We propose a new method for detecting high-frequency gravitational waves (GWs) using high-energy pulsed lasers. Through the inverse Gertsenshtein effect, the interaction between a GW and the laser beam results in the creation of an electromagnetic signal. The latter can be detected using single-photon counting techniques. We present the minimal strain of a detectable GW which only depends on...
