Description
The Canfranc Axion Detection Experiment (CADEx) will search for axions in the yet unexplored mass range of 330–460 micro–electronvolts (µeV). Operating in the W-band (75–110 GHz), CADEx will be installed in a dilution cryostat at the Canfranc Underground Laboratory, combining, for the first time, a cavity haloscope in a strong magnetic field with a Kinetic Inductance Detector (KID) camera. This novel combination is designed to detect the polarization signature of the axion.
Achieving the necessary sensitivity requires advances in two key areas: signal generation and detection. Superconducting technologies provide a key advantage in both. On the one hand, superconducting coatings enhance the performance of the cavities within the haloscope; on the other, superconducting KIDs enable sensitivities that surpass those of traditional HEMT amplifiers. In this talk, I will present the CADEx experiment and the developments achieved over the last years through the use of superconducting technologies.
