Abstract

After a second period of operation of more than three years, the accelerator complex will be stopped for about 18 months, from July 2018. The main purpose of the Long Shutdown 2  (LS2) is the LHC injectors upgrade (LIU). Nevertheless LHC will profit from this period to perform full maintenance of all the equipment, to consolidate part of the machine and to anticipate activities, where possible, of the LHC High Luminosity (HL-LHC) project. During LS2 activities across LHC, Injectors and LHC Experiments will be performed. This paper reviews  all the major LS2 activities (maintenance, consolidation and HL-LHC), identifying those which are on the critical path, those which can be anticipated during End of Year Technical Stops,  and those which will have to be postponed to Long Shutdown 3. The support needed from infrastructure services and logistics will be highlighted, as well as those requiring technical  expertise from the Accelerator and Technology sector. A preliminary LS2 schedule is proposed, including the driving activities and the critical path.
