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…

Search for solar axions produced through the axion-electron coupling using a new GridPix detector at CAST

K. Altenmüller, V. Anastassopoulos, S. Arguedas-Cuendis +61

We present a search for solar axions produced through the axion-electron coupling using data from a novel 7-GridPix detector installed at the CERN Axion Solar Telescope…

The International Axion Observatory (IAXO): case, status and plans. Input to the European Strategy for Particle Physics

A. Arcusa, S. Ahyoune, K. Altenmuller +120

The International Axion Observatory (IAXO) is a next-generation axion helioscope designed to search for solar axions with unprecedented sensitivity. IAXO holds a unique position in…

A new upper limit on the axion-photon coupling with an extended CAST run with a Xe-based Micromegas detector

CAST Collaboration, K. Altenmüller, V. Anastassopoulos +62

Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for…

An accurate solar axions ray-tracing response of BabyIAXO

S. Ahyoune, K. Altenmueller, I. Antolin +124

BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion heliosc…
