Options for ultra-high-frequency gravitational wave detection at DESY — Axel Lindner, Krisztian Peters, •Christoph Reinhardt, Andreas Ringwald, and Aaron Spector — DESY, Hamburg, Germany

Fueled by recent achievements of km-scale gravitational-wave observatories, efforts towards the development of "down to lab-scale" detectors are currently gaining momentum. By virtue of their smaller dimensions, these detectors target gravitational-waves above the established observation window (i.e., 10 to 10⁴ Hz) at "ultra-high-frequencies" (i.e., 10⁴ to 10¹⁹ Hz). The sources proposed for generating potentially observable signals in this frequency range are of cosmological origin or require new physics beyond the Standard Model.

Current work at DESY towards three on-site experiments for axion searches (ALPS II, BabyIAXO, and MADMAX) provides the unique opportunity to exploit synergies with regard to the development of ultra-high-frequency gravitational wave detectors: On the one hand, these axion experiments are also sensitive to gravitational waves via "graviton-to-photon conversion" in the presence of a magnetic field. On the other hand, the underlying infrastructure of the axion experiments, comprising, e.g., a distribution system for liquid helium, can be a prerequisite for implementing dedicated detectors. This talk will present options for ultra-high-frequency gravitational wave searches at DESY, Hamburg.
