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…
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…
Neutral Bremsstrahlung emission in xenon unveiled
C. A. O. Henriques, P. Amedo, J. M. R. Teixeira +90
We present evidence of non-excimer-based secondary scintillation in gaseous xenon, obtained using both the NEXT-White TPC and a dedicated setup. Detailed comparison with first-prin…
The Dynamics of Ions on Phased Radio-frequency Carpets in High Pressure Gases and Application for Barium Tagging in Xenon Gas Time Projection Chambers
NEXT Collaboration, B. J. P. Jones, A. Raymond +107
Radio-frequency (RF) carpets with ultra-fine pitches are examined for ion transport in gases at atmospheric pressures and above. We develop new analytic and computational methods f…
Cosmogenic activation in double beta decay experiments
Susana Cebrian
Double beta decay is a very rare nuclear process and, therefore, experiments intended to detect it must be operated deep underground and in ultra-low background conditions. Long-li…
Demonstration of background rejection using deep convolutional neural networks in the NEXT experiment
NEXT Collaboration, M. Kekic, C. Adams +88
Convolutional neural networks (CNNs) are widely used state-of-the-art computer vision tools that are becoming increasingly popular in high energy physics. In this paper, we attempt…
