TARGET detector evaluation using cosmic ray events for the ν-Angra Experiment

The v-Angra Experiments intends to develop a detector capable of inferring the dissipated power of nuclear reactors by means of measuring the rate of neutrinos events detected by a system installed at sea level a few tens of meters away from the nuclear core. The TARGET detector is a key component of the v-Angra Experiment and of its trigger system since its signals are sent to the trigger electronics which makes use of them to select events for storage. Alongside, cosmic rays represent its main background noise and, consequently, its characteristics when interacting with the detector should be well known in order to enable the experiment to develop an efficient events-selection algorithm. This work presents a study of the characteristics of cosmic rays events in the TARGET detector in order to acquire valuable information for the development of trigger system.
