Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment under construction in China with the main goal of measuring the neutrino mass ordering from reactor antineutrinos. The Top Tracker constitutes part of the veto system of JUNO. Its main task is to track the muons crossing the Central Detector and evaluate the cosmogenic background contribution to the signal. The Top Tracker will be installed on top of JUNO's water Cherenkov and Central detectors and it can precisely track 30\% of the total muon flux at JUNO. It is composed of three layers of several plastic scintillator modules repurposed from OPERA, with each module having two planes of scintillation strips arranged in perpendicular directions for tracking. A new electronics was developed to cope with high background rates at JUNO to trigger and digitize the signal. This poster will present the Top Tracker of JUNO, and discuss its capabilities based on recent detector simulations.
