The VORTEX cavity for the RADES axion haloscope

Jose María García-Barceló, Cristian Cogollos, Babette Döbrich +3

One of the major challenges in axion dark matter haloscope searches is a loss-less tuning mechanism that is able to cover a significant frequency range around the haloscope's centr…

RADES axion search results with a High-Temperature Superconducting cavity in an 11.7 T magnet

S. Ahyoune, A. Álvarez Melcón, S. Arguedas Cuendis +23

We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperatur…

Split-cavity tuning of a rectangular axion haloscope operating around 8.4 GHz

Jessica Golm, Jose María García-Barceló, Sergio Arguedas Cuendis +3

The axion haloscope is the currently most sensitive method to probe the vanishingly small coupling of this prominent Dark Matter candidate to photons. To scan a sizeable axion Dark…
