Development of a Hermetic Gaseous Xenon Detector for Suppressing External Radon Background
Ryuta Miyata, Koki Fujikawa, Rina Harata +3
Radon-induced backgrounds, particularly from Rn and its beta-emitting progeny, present a critical challenge for next-generation liquid xenon (LXe) detectors aimed at probin…

Measurement of the Quantum Efficiency of Electrode Materials for VUV Photons in Liquid Xenon
Shingo Kazama, Naoki Aoyama, Yoshitaka Itow +1
Light dark matter searches using ionization signals in dual-phase liquid xenon (LXe) time projection chambers (TPCs) are limited by low-energy ionization backgrounds, including tho…

Spectral Measurement of the Bi beta-decay to the Po Ground State with XENONnT
E. Aprile, J. Aalbers, K. Abe +170
We report the measurement of the Bi beta-decay spectrum to the ground state of Po using the XENONnT detector. This decay is classified as first-forbidden non-unique…
