Description
The JUNO experiment is under preparation in China.
It's main goal is to determine the $\nu$ mass ordering via the precise measurement of the energy spectrum of $\bar\nu$ from nuclear reactors 53 km away.
To achieve JUNO's goals it is essential to suppress or control the
background processes rate that fake the signal
from $\nu$ in the Central Detector (CD).
The most dangerous of those is the cosmogenic isotopes produced by atmospheric muons.
To reduce their contribution to the $\bar\nu$ spectrum, the Veto system will forbid event detection in vicinity of muon tracks. It
consists of the Top Tracker (TT) and the Water Cherenkov (WC) detector surrounding the CD.
The TT consists of 3 layers of scintillator strips covering about
1/3 of the surface above the WC detector. The TT will precisely reconstruct
the trajectory of muons to study and supress the cosmogenic background.
This poster will discuss JUNO's Top Tracker design and expected performance.
