Characterization of large diameter ultra-thin vacuum windows for soft X-ray applications

K. Desch, E. Ferrer-Ribas, F. J. Iguaz +3

We present novel, ultra-thin, large-diameter silicon nitride windows for various soft X-ray applications. Together with the company NORCADA, we developed windows with 200 nm and 30…

Optical readout of MPGDs with solid wavelength shifters

F. M. Brunbauer, A. Cools, M. Cortesi +20

Optical readout of MicroPattern Gaseous Detectors (MPGDs) makes use of the high granularity of imaging sensors to achieve good spatial resolution for radiation imaging and particle…

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…

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…
