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…
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…
Low-energy threshold demonstration for dark matter searches in TREX-DM with an Ar source produced at CNA HiSPANoS
J. Castel, S. Cebrián, T. Dafni +16
We report on the successful implementation of an Ar calibration source in the TREX-DM detector, a high-pressure time projection chamber designed for low-mass dark matter sea…
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…
Using Micromegas detectors for direct dark matter searches: challenges and perspectives
K. Altenmueller, . Antolin, D. Calvet +27
Gas time projection chambers (TPCs) with Micromegas pixelated readouts are being used in dark matter searches and other rare event searches, due to their potential in terms of low…
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…
