We present the status of Angra Neutrino Experiment, aimed at developing an antineutrino detector for monitoring nuclear reactor activity. The comprises a 1.42 m3 Gadolinium-Water Cerenkov target, surrounded by 50 cm water shielding, placed inside commercial container about 30 m from core, II power plant, Brazil. 4 GW thermal will provide few thousand interactions per day. main challenge experiment is to overcome very high cosmic ray induced background sea level. text describes construction...
The Neutrinos Angra Experiment has completed a major step by finishing the comissioning of detector and data acquisition system at experimental site located in dos Reis nuclear power plant. experiment consists water-based associated electronics, both designed with goal detecting electron antineutrinos produced reactor. detection is possible due to Inverse Beta Decay, where final products water are photons UV-to-visible range spectrum. assembled comprises three active volumes filled water:...
The Neutrinos Angra Experiment, a water-based Cherenkov detector, is located at the dos Reis nuclear power plant in Brazil. Designed to detect electron antineutrinos produced reactor, primary objective of experiment demonstrate feasibility monitoring reactor activity using an antineutrino detector. This effort aligns with International Atomic Energy Agency (IAEA) program identify potential and novel technologies applicable nonproliferation safeguards. Operating on surface presents challenges...
The ν-Angra experiment aims to estimate the flux of antineutrino particles coming out from Angra II nuclear reactor. Such is proportional thermal power released in fission process and therefore can be used infer quantity fuel that has been burned during a certain period. To do so, Collaboration developed an detector complete acquisition system readout store signals generated by its sensors. entire detection installed inside container laboratory placed beside dome reactor, restricted zone...
The Neutrinos Angra (ν-Angra) Experiment aims to construct an antineutrinos detection device capable of monitoring the dos Reis nuclear reactor activity. proposed system considers a detector operating on surface, which makes it exposed high rate background noise, mainly due cosmic rays. Therefore, veto has fundamental role in experiment viability. This paper proposes innovative methodology monitor gain variation photomultiplier tubes system, during operation, based rays muons.
The Neutrinos Angra Experiment aims at monitoring nuclear plants by detecting antineutrino particles coming out from its fuel burn-up process. Collaboration developed a fully-equipped detector to accomplish this task. It is currently in operation on the surface and next dome of II reactor. Selecting antineutrinos events challenge task due high level background noise produced cosmic ray particles. One main parameters used select number photons acquired detector's sensors. This quantity...
In this work, a battery of measurements have been carried out with the objective characterizing target detector Neutrinos Angra Experiment using cosmic rays based trigger. It is its first assessment after was fully equipped all 32 PMTs, as foreseen by project, and custom-based readout electronics.

The Neutrinos Angra (ν-Angra) Experiment has the objective of developing a compact surface detector capable monitoring activity nuclear reactors. collaboration ν-Angra makes use Geant4 package to simulate interactions occurring inside detector. outcome this Geant4-based software provides time, position and energy photons that reach sensors; therefore none information about electrical signal formation is given. In context, work proposes method coming out from acquisition chain. such chain...
The v-Angra Experiments intends to develop a detector capable of inferring the dissipated power nuclear reactors by means measuring rate neutrinos events detected system installed at sea level few tens meters away from core. TARGET is key component Experiment and its trigger since signals are sent electronics which makes use them select for storage. Alongside, cosmic rays represent main background noise and, consequently, characteristics when interacting with should be well known in order...

The Neutrinos Angra Experiment aims at developing a system capable of monitoring the fuel-burning process nuclear reactors. This is based on an antineutrino detector located few meters far from core II reactor. One main parameters used to select events released energy left by particle when interacting with medium which, in turn, proportional amplitude and area signals generated detector's transducers. However, estimation such quantities may lose accuracy due saturation effects caused...
