    "abstract": "In this technical note the rf control and detection system for a detector of\nsmall harmonic displacements based on two coupled microwave cavities (PACO) is\npresented. The basic idea underlying this detector is the principle of\nparametric power conversion between two resonant modes of the system,\nstimulated by the (small) harmonic modulation of one system parameter. In this\nexperiment we change the cavity length applying an harmonic voltage to a\npiezo-electric crystal. The system can achieve a great sensitivity to small\nharmonic displacements and can be an interesting candidate for the detection of\nsmall, mechanically coupled, interactions (e.g. high frequency gravitational\nwaves).",
