Front-end's control system and threshold scan evaluation for the ν-Angra Experiment

The v-Angra experiment aims to develop a new technique to monitor the activity of nuclear reactors through a compact surface detector. As the thermal power released in the fission is proportional to the flux of antineutrinos, by measuring the flow rate of these particles, it is possible to infer the quantity of fuel that has been burned and its composition. As the detector operates at a noisy environment, it is important to make a precise adjustment of the threshold level in order to detect single photoelectron (SPE) signals more efficiently. Since the access to the nuclear power plant is restricted, the possibility to make this configuration remotely is important. This work describes a control system designed to remotely configure the v-Angra's front-end parameters and some results obtained with its implementation.
