The installation of five modules of the TRD will follow and so complete this complex detector system, which consists of 18 units,  In addition to these mainstream detector activities, all of the 18 ALICE subdetectors underwent major improvements during LS1 while the computers and discs of the online systems are replaced, followed by upgrades of the operating systems and online software. All of these efforts are to ensure that ALICE is in good shape for the three-year LHC running period after LS1, when the collaboration looks forward to heavy-ion collisions at the top LHC energy of 5.5 TeV/nucleon at luminosities in excess of 1027 Hz/cm2. The ALICE collaboration has plans for a major upgrade during the next long shutdown, LS2, currently scheduled for 2018. Then the entire silicon tracker will be replaced by a monolithic-pixel tracker system built from ALPIDE chips; the time-projection chamber will be upgraded with gaseous electron-multiplier (GEM) detectors for continuous read-out and the use of new microelectronics; and all of the other subdetectors and the online systems will prepare for a 100-fold increase in the number of events written to tape.
