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…

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…

Daily modulations and broadband strategy in axion searches. An application with CAST-CAPP detector

F. Caspers, C. M. Adair, K. Altenmüller +60

It has been previously advocated that the presence of the daily and annual modulations of the axion flux on the Earth's surface may dramatically change the strategy of the axion se…

Background discrimination with a Micromegas detector prototype and veto system for BabyIAXO

K. Altenmüller, J. F. Castel, S. Cebrián +22

In this paper we present measurements performed with a Micromegas X-ray detector setup. The detector is a prototype in the context of the BabyIAXO helioscope, which is under constr…
