【 摘 要 】

During the second long shutdown (LS2) of the LHC the ALICE detector will be improved with the installation of an upgraded Inner Tracking System (ITS) and a new Muon Forward Tracker (MFT). These detectors will crucially contribute to the precise characterization of the high-temperature, strongly-interacting medium created in ultra-relativistic Pb-Pb collisions at √sNN= 5.5 TeV. In the central barrel, the upgraded ITS will consist of seven cylindrical layers of silicon pixel detectors, starting at a radial distance of 22.4 mm from the beam axis. At forward rapidity, the MFT will be composed of five silicon pixel planes added in the acceptance of the existing Muon Spectrometer (-4 -1, as foreseen for the ALICE upgrade programme.
