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…
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…
Purification Efficiency and Radon Emanation of Gas Purifiers used with Pure and Binary Gas Mixtures for Gaseous Dark Matter Detectors
K., Altenmüller, J. F. Castel +22
Rare event searches require extreme radiopurity in all detector components. This includes the active medium, which in the case of gaseous detectors, is the operating gas. The gases…
Recoil imaging for directional detection of dark matter, neutrinos, and physics beyond the Standard Model
C. A. J. O'Hare, D. Loomba, K. Altenmüller +164
Recoil imaging entails the detection of spatially resolved ionization tracks generated by particle interactions. This is a highly sought-after capability in many classes of detecto…
AlphaCAMM, a Micromegas-based camera for high-sensitivity screening of alpha surface contamination
Konrad Altenmüller, Juan F. Castel, Susana Cebrián +12
Surface contamination of Rn progeny from the U natural decay chain is one of the most difficult background contributions to measure in rare event searches experimen…
Conceptual Design of BabyIAXO, the intermediate stage towards the International Axion Observatory
A. Abeln, K. Altenmüller, S. Arguedas Cuendis +123
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 heliosc…
