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…
A study of multicavity concept applied to hexagonal coaxial haloscopes
J. M. García-Barceló, Jose R. Navarro-Madrid, Alejandro Díaz-Morcillo
In this work, a study on the development of scalable multicavity architectures for axion haloscopes, based on a hexagonal coaxial geometry operating at GHz frequencies, is pre…
Microwave Technologies in Experiments for Detection of Dark Matter Axions
Jose R. Navarro-Madrid, Jose María García-Barceló, Alejandro Díaz-Morcillo
This article reviews different microwave technologies used in dark matter axion detection experiments with resonant cavities. The general concepts of the experiment are presented a…
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…
