In the near future BabyIAXO will be the most powerful axion helioscope, relying on a custom-made magnet of two bores of 70 cm diameter and 10 m long, with a total available magnetic volume of more than 7 m3. In this document, we propose and describe the implementation of low-frequency axion haloscope setups suitable for operation inside the BabyIAXO magnet. [...]

Design of New Resonant Haloscopes in the Search for the Dark Matter Axion: A Review of the First Steps in the RADES Collaboration / Díaz-Morcillo, Alejandro (Cartagena Politecnica U.) ; Barceló, José María García (Cartagena Politecnica U.) ; Guerrero, Antonio José Lozano (Cartagena Politecnica U.) ; Navarro, Pablo (Cartagena Politecnica U.) ; Gimeno, Benito (Valencia U., IFIC) ; Cuendis, Sergio Arguedas (CERN) ; Melcón, Alejandro Álvarez (Cartagena Politecnica U.) ; Cogollos, Cristian (Barcelona, IEEC) ; Calatroni, Sergio (CERN) ; Döbrich, Babette (CERN) et al.
Within the increasing interest in the dark matter axion detection through haloscopes, in which different international groups are currently involved, the RADES group was established in 2016 with the goal of developing very sensitive detection systems to be operated in dipole magnets. This review deals with the work developed by this collaboration during its first five years, from the first designs, based on the multi-cavity concept, aiming to increase the haloscope volume and, so, to improve its sensitivity, their evolution, the data acquisition design, and, finally, the first experimental run.

Conceptual Design of BabyIAXO, the intermediate stage towards the International Axion Observatory / IAXO Collaboration
This article describes BabyIAXO, an intermediate experimental stage of the International Axion Observatory (IAXO), proposed to be sited at DESY. IAXO is a large-scale axion helioscope that will look for axions and axion-like particles (ALPs), produced in the Sun, with unprecedented sensitivity. [...]

New Upper Limit on the Axion-Photon Coupling with an Extended CAST Run with a Xe-Based Micromegas Detector / CAST Collaboration
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 solar axions via their back conversion to X-ray photons in a 9-T 10-m long magnet directed towards the Sun. [...]

First results of the CAST-RADES haloscope search for axions at 34.67 μeV / CAST Collaboration
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67μeV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. [...]

On the use of ferroelectric material in the detection of dark matter axions / Barceló, J.M. García (Cartagena Politecnica U.) ; Melcón, A. Álvarez (Cartagena Politecnica U.) ; Cuendis, S.

(Cartagena Politecnica U.) ; Navarro, P. (Cartagena Politecnica U.) ; Wuensch, W. (CERN)
Tuning is an essential requirement for the search of dark matter axions employing haloscopes since its mass is not known yet to the scientific community. At the present day, most haloscope tuning systems are based on mechanical devices which can lead to failures due to the complexity of the environment in which they are used. [...]
