Schematic cross-section of the ALICE detector perpendicular to the LHC beam direction (status of the detector since the start of LHC \run{2}). The central barrel detectors cover the pseudorapidity range $| \eta | \lesssim 0.9 $ and are located inside the solenoid magnet, which provides a magnetic field with strength $B$ = \SI{0.5}{\tesla} along the beam direction.
