ν-Angra Readout Electronics and Target Detector Assessment using a Cosmic Rays based Trigger

In this work, a battery of measurements have been carried out with the objective of characterizing the target detector of the Neutrinos Angra Experiment using a cosmic rays based trigger. It is its first assessment after the detector was fully equipped with all the 32 PMTs, as foreseen by the project, and its custom-based readout electronics. The $\nu -$ Angra detector was constructed with the purpose of measuring antineutrinos particles generated in the fission process of the Angra dos Reis Nuclear Reactor. Before transporting it to the nuclear reactor facility, it is important to measure its operational characteristics as a first step of the commissioning stage. The achieved results describing some of the main characteristics of the detector system are presented in this document.
