Improvement and assessment of the radiopurity of Micromegas readout planes

Juan Castel, Susana Cebrian, Theopisti Dafni +17

Micromesh Gas Structures (Micromegas) as readout of gaseous Time Projection Chambers (TPCs) are being considered in experiments investigating rare phenomena, like the nuclear doubl…

Spatial resolution studies with the BabyIAXO Micromegas prototype

A. Quintana, J. Castel, S. Cebrián +20

The spatial resolution of the Micromegas prototype developed for the BabyIAXO experiment was evaluated using a low-energy X-ray beam at the SOLEIL synchrotron facility. BabyIAXO, c…

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…

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…

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…
