The ALICE Collaboration is preparing a major upgrade of the ALICE detector,
planned for installation in the second long LHC shutdown. The construction is
expected to be completed by 2020 for data taking until 2029. A key element of
the ALICE upgrade is the construction of a new, ultra-light, high-resolution
Inner Tracking System (ITS).

With respect to the current ITS, this upgrade is aiming at a better position
resolution (5 micron), a lower material budget (0.3% X0) and a faster readout
(up to 100 kHz in Pb-Pb collisions). This will be obtained by seven concentric
detector layers based on an advanced Monolithic Active Pixel Sensor (MAPS)
chip, with a pixel pitch of 30x30um^2. The general layout and main components
of the new ITS, a summary of the R&D activities, the current status and an
outlook will be presented.
