Description
In a joint effort between DESY/U. Hamburg and Fermilab, we are advancing the R&D program originally initiated by the MAGO collaboration (led by INFN Genoa) to search for high-frequency gravitational waves using superconducting radio-frequency (SRF) cavities. We are using a MAGO prototype cavity, fabricated nearly two decades ago but never previously tested. Following a detailed mechanical survey, we performed plastic tuning to correct geometric deviations, and carried out extensive measurements and simulations of its mechanical resonances and electromagnetic properties, which are key factors for evaluating its GW coupling potential. Ongoing cryogenic tests focus on noise characterization and the development of cavity control and signal readout systems. This effort lays the foundation for a first GW search with the existing cavity and informs the design of next-generation cavities.
