摘要：

ALICE has devised a comprehensive upgrade strategy to enhance its physics capabilities and to exploit the LHC running conditions after the second long shutdown of the LHC scheduled in 2018-2019. Within this upgrade programme, the upgrade of the Inner Tracking System (ITS) forms an important part. The upgraded ITS will have a barrel geometry consisting of seven layers of Monolithic Active Pixel Sensors (MAPS) with high granularity, which would fulfil the material budget, readout and radiation hardness requirements for the upgrade. In this contribution, an overview of the upgraded ITS, its technology and performance studies are presented. (C) 2014 CERN. Published by Elsevier B.V. All rights reserved.
