From: Observation of two-neutrino double electron capture in 124Xe with XENON1T

Extended Data Fig. 1

Interaction depth Z versus squared radius R2 for events with energies 80–140 keV. High-density areas correspond to the edges of the TPC, where most of external β and γ radiation is absorbed. The 1,502-kg fiducial volume is indicated by the solid red line. Further segmentation into an inner (1.0 t) and an outer (0.5 t) volume is marked by the black dashed line.
