The VORTEX cavity for the RADES axion haloscope
Jose MarÃa GarcÃa-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. GarcÃa-Barceló, Jose R. Navarro-Madrid, Alejandro DÃaz-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…
RADES axion search results with a High-Temperature Superconducting cavity in an 11.7 T magnet
S. Ahyoune, A. Ãlvarez 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 MarÃa GarcÃa-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…
Microwave Technologies in Experiments for Detection of Dark Matter Axions
Jose R. Navarro-Madrid, Jose MarÃa GarcÃa-Barceló, Alejandro DÃaz-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…
