چکیده

By performing global fits to inverse beta decay (IBD) yield measurements from existing neutrino experiments based at highly $^{235}$U enriched reactor cores and conventional low-enriched cores, we explore current direct bounds on production by the sub-dominant fission isotope $^{241}$Pu. For this nuclide, determine an IBD of $\sigma_{241}$ = 8.16 $\pm$ 3.47 cm$^2$/fission, a value (135 58)% that conversion models. This constraint is shown derive non-linear relationship between burn-in $^{241}$Pu $^{239}$Pu in fuel. considering new hypothetical high-enriched, low-enriched, mixed-oxide, fast facilities, investigate feasible limits future knowledge yields for $^{235}$U, $^{238}$U, $^{239}$Pu, $^{241}$Pu, $^{240}$Pu. We find first measurement $^{240}$Pu can be performed plutonium-burning reactors, while suite correlated multiple types achieve precision meets or exceeds theoretical predictions.

Terrestrial Antineutrino Flux Measurements

Electron antineutrinos accompanying the β-decays of long-lived isotopes of uranium, thorium, and potassium in the earth carry information about the quantity and distribution of these geologically important, heat-producing isotopes. This letter discusses terrestrial antineutrino flux measurements at both a continental and an oceanic site. A combined analysis of both measurements provides informa...

Measurement of the Reactor Antineutrino Flux and Spectrum at Daya Bay.

This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296 721 and 41 589 inverse β decay (IBD) candidates were detected in the near and far hall...

Improved Measurement of the Reactor Antineutrino Flux and Spectrum at Daya Bay

A new measurement of the reactor antineutrino flux and energy spectrum by the Daya Bay reactor neutrino experiment is reported. The antineutrinos were generated by six 2.9 GWth nuclear reactors and detected by eight antineutrino detectors deployed in two near (560 m and 600 m flux-weighted baselines) and one far (1640 m flux-weighted baseline) underground experimental halls. With 621 days of da...

Trigger for the SoLid Reactor Antineutrino Experiment

SoLid, located at SCK-CEN in Mol, Belgium, is a reactor antineutrino experiment at a very short baseline of 5.5 – 10m aiming at the search for sterile neutrinos and for high precision measurement of the neutrino energy spectrum of Uranium-235. It uses a novel approach using Lithium-6 sheets and PVT cubes as scintillators for tagging the Inverse Beta-Decay products (neutron and positron). Being ...
