5. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Objective and Scope The LS2 Committee is: THE executive committee dealing with all technical and organisational aspect of the LS2 (2019-20), including EYETS 2016-17 and YETS 2017-18 periods. It includes the accelerators themselves as well and the associated transfer lines and facilities. It covers all activities carried out and resources needed in the context of the LS2 period over the whole CERN accelerator facilities. 5

6. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Objective and Scope It will : Examine and define the safety conditions taking into account co-activities; Monitor all the activities entering in this scope and corresponding schedules (EYETS, YETS, LS2): Closely monitor and continuously optimise the schedule to ensure best use of resources and minimise impact of any unforeseen event. Examine and decide changes of activities and priorities. Follow-up the quality control; It is : THE information channel towards all departments, groups and experiments concerned by the LS2; The place to introduce and assess any new proposal recommended by the LMC or IEFC involving work during the EYETS 2016-17, YETS 2017-18 and LS2 (2019-20). 6

7. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Objective and Scope 7 Long Shutdown 2 (LS2) Project Project Scope & Mandate of LS2 coordinator (1/2) The project scope covers all activities carried out and resources needed in the context of Long Shutdown 2 over the whole CERN accelerator facilities. Long Shutdown 2 “Period” (LS2) EYETS 2016-17 YETS 2017-18 “LS2” 2019-2020

8. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Long Shutdown 2 (LS2) Project Project Scope & Mandate of LS2 coordinator (1/2) The project scope covers all activities carried out and resources needed in the context of Long Shutdown 2 over the whole CERN accelerator facilities. The mandate of the project coordinator includes: Prior to the start of the LS2, the definition of main works to be achieved over the LS2 and of potential options based on priorities given to activities. This study shall highlight in particular LS2 duration and resources needed for each option and be presented to the Directorate by Q3-2016 for final decision; The definition of a CERN-wide “resource-loaded planning”, ensuring the compatibility of resources and planning across the LHC Machine and LHC Experiments; 8 José Miguel Jimenez, LS2 Coordinator

9. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Long Shutdown 2 (LS2) Project Project Scope & Mandate of LS2 coordinator (2/2) The preparation, coordination and follow-up till completion of all LS2 activities in the frame of the LIU, HL-LHC Projects and other CERN approved projects. Work packages will define: The work absolutely essential to achieve the LS2 objectives (activities which will bear a Priority 1-2), which execution will be closely followed up by the LS2 Coordinator; The work which can be postponed to the LS3 (activities which will bear a Priority >2), which impact on LS3 will be assessed by the LS2 Coordinator. The flexibility to use the end-of-year technical stops before and after the LS2 to decrease the load of the LS2 is left at the discretion of the LS2 coordinator and is also part of the scope of the project. 9 José Miguel Jimenez, LS2 Coordinator

12. 1 st of April 2016 http://indico.cern.ch/event/ABCDED/ 1 st LS2C Interfaces / Reporting The LS2C reports to the director of the A&T Sector and to the Enlarged Directorate. The LSC shall assess any new proposal recommended by the LMC or IEFC which involves work during LS2 Period in order to decide if this can be incorporated into the overall shutdown schedule and if, as a result, it is necessary to suppress or delay other activities. 12
