The Neutrinos Angra (ν-Angra) Experiment aims to construct an antineutrinos detection device capable of monitoring the Angra dos Reis nuclear reactor activity. The proposed system considers a detector operating on the surface, which makes it exposed to a high rate of background noise, mainly due to cosmic rays. Therefore, the veto system has a fundamental role in the experiment viability. This paper...
This paper proposes a detailed evaluation of the impact of digital filters when applied to the Neutrinos Angra Experiment. The signals coming out from its front-end electronics are digitized and then sent to an FPGA where further processing might be carried out. In this context, this work proposes a set of peak amplitude estimators optimized to have minimum variance. Constrained optimization technique...
The Muon Portal Project has as its goal the design and construction of a real-size working detector prototype in scale 1:1, to inspect the content of travelling containers by means of the secondary cosmic-ray muon radiation and to recognize high-Z hidden materials (i.e. U, Pu). The tomographic image is obtained by reconstructing the input and output trajectories of each muon when it crosses the container...
The Muon Portal Project goal is the design and construction of a working detector prototype in scale 1∶1, to inspect the content of travelling containers by means of the secondary cosmic-ray muon radiation and recognize high-Z hidden materials (U, Pu or other fissile samples). The radiographic image is obtained by reconstructing the input and output trajectories of each muon and consequently the scattering...
