Abstract New developments in liquid scintillators, high-efficiency, fast photon detectors, and chromatic sorting have opened up the possibility for building a large-scale detector that can discriminate between Cherenkov scintillation signals. Such could reconstruct particle direction species using light while also having excellent energy resolution low threshold of scintillator detector. Situated deep underground, utilizing new techniques computing reconstruction, this achieve unprecedented...
The reactor antineutrino anomaly might be explained by the oscillation of antineutrinos toward a sterile neutrino eV mass. In order to explore this hypothesis, STEREO experiment measures energy spectrum in six different detector cells covering baselines between 9 and 11 m from compact core ILL research reactor. Letter, results 66 days turned on 138 off are reported. A novel method extract rates has been developed based distribution pulse shape discrimination parameter. test new is performed...
The STEREO experiment is a very short baseline reactor antineutrino aiming at testing the hypothesis of light sterile neutrinos as an explanation deficit observed neutrino interaction rate with respect to predicted rate, known Reactor Antineutrino Anomaly. detector center located 10 m away from compact, highly 235U enriched core research nuclear Institut Laue Langevin in Grenoble, France. This paper describes site, components and associated shielding designed suppress external sources...
Abstract Super-Kamiokande has been searching for neutrino bursts characteristic of core-collapse supernovae continuously, in real time, since the start operations 1996. The present work focuses on detecting more distant whose event rate may be too small to trigger but identified using an offline approach. analysis data collected from 2008 2018 found no evidence bursts. This establishes upper limit 0.29 yr −1 out 100 kpc at 90% C.L. For that fail explode and collapse directly black holes...
Abstract We present the sensitivity of Theia experiment to low-energy geo- and reactor antineutrinos. For this study, we consider one possible proposed designs, a 17.8-ktonne fiducial volume -25 detector filled with water-based liquid scintillator placed at Sanford Underground Research Facility (SURF). demonstrate ’s measure antineutrinos via inverse-beta decay interactions after year data taking $$11.9 \times 10^{32}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow>...
The STEREO experiment will search for a sterile neutrino by measuring the anti-neutrino energy spectrum as function of distance from source, ILL nuclear reactor. A dedicated electronic system, hosted in single microTCA crate, was designed this experiment. It performs triggering two stages with various selectable conditions, processing and readout via UDP/IPBUS 68 photomultiplier signals continuously digitized at 250 MSPS. Additionally, detector performance monitoring, electronics allow...
In 2011, a re-evaluation of the antineutrino spectrum emitted by nuclear reactors revealed 6% deficit between observed flux and expected one. This anomaly is significant at 2.9$σ$ can be explained new oscillation short range due to light sterile neutrino, with parameter $Δm^2=\mathcal{O}(\text{eV})$. The STEREO detector in construction ILL will first ever measure precision its very distance (9-11m) it able confirm or reject existence this neutrino. following we introduce relevant study...
The stereo experiment is searching for a non-standard oscillation in the propagation of anti-neutrinos produced by nuclear reactor which could be sign existence sterile state eV mass and origin anti-neutrino anomaly. In this paper, results from 66 days turned on 138 off are reported excluding large amplitude oscillations. A special focus put data analysis studies correlated backgrounds. particular background measured periods discussed. This mainly originates neutrons cosmic radiation.
