      abstract     = {Heterodyne detection using microwave cavities is a
                      promising method for detecting high-frequency gravitational
                      waves (GWs) or ultralight axion dark matter. In this work,
                      we report on studies conducted on a spherical 2-cell cavity
                      developed by the MAGO collaboration for high-frequency GWs
                      detection. Although fabricated around 20 years ago, the
                      cavity had not been used since. Due to deviations from the
                      nominal geometry, we conducted a mechanical survey and
                      performed room-temperature plastic tuning. Measurements and
                      simulations of the mechanical resonances and electromagnetic
                      properties were carried out, as these are critical for
                      estimating the cavity’s GW coupling potential. Based on
                      these results, we plan further studies in a cryogenic
                      environment. The cavity characterisation does not only
                      provide valuable experience for a planned physics run but
                      also informs the future development of improved cavity
                      designs.},
