Abstract

We report a new measurement of electron antineutrino disappearance using the fully constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected from October 2012 to November 2013 resulted in a total exposure of 6.9×10 ⁵ GW _th ton days, a 3.6 times increase over our previous results. Improvements in energy calibration limited variations between detectors to 0.2%. Removal of six ²⁴¹Am- ¹³C radioactive calibration sources reduced the background by a factor of 2 for the detectors in the experimental hall furthest from the reactors. Direct prediction of the antineutrino signal in the far detectors based on the measurements in the near detectors explicitly minimized the dependence of the measurement on models of reactor antineutrino emission. The uncertainties in our estimates of ²sin2θ ₁₃ and |Δm ² _ee| were halved as a result of these improvements. An analysis of the relative antineutrino rates and energy spectra between detectors gave ²sin2θ ₁₃=0.084±0.005 and |Δm ² _ee|=(2.42±0.11)×10 ^–3 eV ² in the three-neutrino framework.

Measurement of the Electron Antineutrino Oscillation with 1958 Days of Operation at Daya Bay

Journal Article Adey, D. ; An, F. P. ; Balantekin, A. B. ; ... - Physical Review Letters

Here, we report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ¯ν _e inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ⁹Li and ⁸He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves itsmore »« less

Measurement of electron antineutrino oscillation based on 1230 days of operation of the Daya Bay experiment

Journal Article An, F. P. ; Balantekin, A. B. ; Band, H. R. ; ... - Physical Review D

Here, a measurement of electron antineutrino oscillation by the Daya Bay Reactor Neutrino Experiment is described in detail. Six 2.9-GWth nuclear power reactors of the Daya Bay and Ling Ao nuclear power facilities served as intense sources of ¯ν _e’s. Comparison of the ¯ν _e rate and energy spectrum measured by antineutrino detectors far from the nuclear reactors (~1500–1950 m) relative to detectors near the reactors (~350–600 m) allowed a precise measurement of ¯ν _e disappearance. More than 2.5 million ¯ν _e inverse beta-decay interactions were observed, based on the combination of 217 days of operation of six antineutrino detectorsmore »« less

Measurement of the reactor antineutrino flux and spectrum at Daya Bay

Journal Article D. E. Jaffe ; Bishai, M ; Diwan, M. ; ... - Physical Review Letters

This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9~GW _th nuclear reactors with six detectors deployed in two near (effective baselines 512~m and 561~m) and one far (1,579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296,721 and 41,589 inverse beta decay (IBD) candidates were detected in the near and far halls, respectively. The measured IBD yield is (1.55 ± 0.04) × 10 ^–18 cm ²/GW/day or (5.92 ± 0.14) × 10 ^–43 cm ²/fission. This flux measurement is consistent with previous short-baseline reactor antineutrino experimentsmore »« less
