Abstract

AbstractXenon dual-phase time projection chambers designed to search for weakly interacting massive particles have so far shown a relative energy resolution which degrades with energy above $$\sim $$∼ 200 keV due to the saturation effects. This has limited their sensitivity in the search for rare events like the neutrinoless double-beta decay of $$^{136} \hbox {Xe}$$136Xe at its Q value, $$Q_{\beta \beta }\simeq 2.46\,\hbox {MeV}$$Qββ≃2.46MeV. For the XENON1T dual-phase time projection chamber, we demonstrate that the relative energy resolution at $$1\,\sigma /\mu $$1σ/μ is as low as ($$0.80 \pm 0.02$$0.80±0.02) % in its one-ton fiducial mass, and for single-site interactions at $$Q_{\beta \beta }$$Qββ. We also present a new signal correction method to rectify the saturation effects of the signal readout system, resulting in more accurate position reconstruction and indirectly improving the energy resolution. The very good result achieved in XENON1T opens up new windows for the xenon dual-phase dark matter detectors to simultaneously search for other rare events.
