Description
After a second period of operation of more than 3 years, the accelerator complex will be stopped for about 18 months. The main purpose of the Long Shutdown 2 (LS2) is the LHC injectors upgrade (LIU). Nevertheless LHC will profit from this period to perform the 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. This talk will review all the major LS2 activities (maintenance, consolidation and HL-LHC), identifying those which can be anticipated during end of year technical stops, and those which will have to be postponed to Long Shutdown3. The support needed from infrastructure services and logistics will be highlighted, as well those requiring technical expertise from the Accelerator and Technology sector. A preliminary LS2 schedule will be proposed, including the driving activities and the critical path.
