      abstract     = {In the last years, low frequency gravitational waves (GWs)
                      have been consistently measured by the LIGO-Virgo
                      collaboration, but little to no attention has been paid to
                      higher frequencies GWs in the range of 10 kHz to 100 MHz, at
                      which confirmation for current theories or even new physics
                      could be hidden.The MAGO 2.0 project aims at filling this
                      gap in the parameter space using superconducting
                      radio-frequency (SRF) cavities. Exploiting the excellent
                      Q-factors of these resonators, we plan to detect tiny
                      harmonic deformations induced by GWs which change the
                      boundary conditions of the oscillating electromagnetic
                      field.We present the results of the first cold tests ran at
                      DESY and FNAL using the cavity prototype built 20 years ago
                      at the end of the MAGO collaboration, characterizing the RF
                      spectrum, Q-factor and surface resistance. Additionally we
                      introduce the mechanical vibration spectrum
                      characteriza-tion and the RF response of the cavity with the
                      injection of a “fake GW” signal using piezoelectric
                      actuators.},
