  1. Framework schedule from YETS 2015 to LS3 Marzia Bernardini, on behalf of OSS team Joint LIU and HL-LHC meeting, 15th October 2015

  2. Contents General information YETS and EYETS - activities related to regular maintenance - length of YETS and EYETS for LHC and Injectors LS2 - Framework for LHC - Framework for Injectors Beyond LS3: overview for LHC and Injectors Methodology & Interfaces with EN-MEF Coordination & Schedule & Safety aspects Conclusion M. Bernardini - 15th October 2015

  3. Overview & Contingencies • Contingency strategy • There are NO contingencies in the global schedule, from the general coordination point of view • For the Injectors, a long recommissioning period is foreseen to mitigate potential issues related to the restart of the machines M. Bernardini - 15th October 2015

  4. YETS regular maintenance & tests LHC - CV maintenance in LHC and its Experiments 10 wks • Safety tests (mainly during Christmas Break) by GS-ASE and EN-EL • Minor regular maintenance on cryogenic equipment and rotating machines • LHC Recommissioning  1 wkcan be considered as baseline if not major interventions occur during the YETS Regular maintenance activities on other equipment are performed in the shadow of the activities listed above • In conclusion the minimum length (beam to beam) of the YETS for LHC is 13 wks(including the Christmas Break) M. Bernardini - 15th October 2015

  5. YETS regular maintenance & tests SPS • Hardware tests (mainly magnet tests) before and after the shutdown 2wk • CV maintenance for SPS (not including North Area)  6wks • Activities related to Recommissioning by BE-OP3 wks can be considered as a baseline, but this duration can evolve • The safety tests by GS-ASE and EN-EL Regular maintenance activities on other equipment are performed in the shadow of the activities listed above • In conclusion the minimum length (beam to beam) of the YETS for the SPS is 13 wks* (including the Christmas Break) * The RP cool down period is not included M. Bernardini - 15th October 2015

  6. YETS regular maintenance & tests PSB & PS • Hardware tests (mainly magnet tests) before and after the shutdown 1wk • CV maintenance for PSB, PS, Linac2 and Linac4 (not including Isolde, AD, East Area, CTF3 and n-TOF)  5wks • Activities related to Recommissioning by BE-OP 3wks can be considered as a baseline, but this duration can evolve • The safety tests by GS-ASE and EN-EL Regular maintenance activities on other equipment are performed in the shadow of the activities listed above • In conclusion the minimum length (beam to beam) of the YETS for the PS and PSB is 11 wks* (including the Christmas Break) * The RP cool down period is not included M. Bernardini - 15th October 2015

  7. YETS: reality vs baseline YETS 2015-2016 and 2017-2018 • LHC & SPS: YETS kept to 13 wks • PSB and PS: duration aligned to LHC and SPS. Due to the following requests: • Decabling project and its implementation strategy; • Anticipation of LIU activities during YETS Duration of YETS 2015-2016 & 2017-2018 M. Bernardini - 15th October 2015

  8. EYETS 2016-2017 LHC In addition to the baseline there was a request from CMS to anticipate works of LS2, to prepare the Experiment to cope with the 2e34 cm-2s-1 luminosities. These works imply the full opening of Endcaps and impact the duration of the YETS INJECTORS The implementation strategy of the decabling project foresees a massive decabling campaign in the PSB during the Year End Technical Stop 2016-2017 Extended Year End Technical Stop 2016-2017 M. Bernardini - 15th October 2015

  9. LS2 Framework for LHC During the LS2 three main categories of activities will be implemented • Maintenance: Cryogenics, Cooling and Ventilation, Vacuum, Electrical Systems, Collimation, Access System, Fire detection, ODH, … • Projects: HL-LHC • Consolidation & Other activities: this concerns all equipment in the LHC machine LS2 Days: https://indico.cern.ch/e/436424 The Baseline as for Chamonix 2014 foresaw a Length of LS2 of 18 Months, but following the requests of the Hi-Lumi LHC project and the outcomes of the cost and schedule review, the Length of LS2 is now extended to 24 Months.

LS2@LHC: Proposal of First Draft skeleton TESTS and WARM UP CRYO Maintenance ELECTRICAL Maintenance & Consolidation Magnets replacement Other activities… HL activities @ P2, P4, P6 and P8 Lift replacement HL activities @ LSS7 Cool Down @ P7 COOL DOWN, TESTS and HWC Depending on the cool down and warm up sequence Windows available for activities  Between 18 and 22 Months

  13. LS2 Framework for Injectors Defined by LIU project L4 7 months PSB 15.5 months PS 11.5 months SPS 18 months Start of LS2 for the injectors: • Surface activities for Linac2, Linac4 and PSB machines will start in November 2018, during tunnel RP cooling. • All other surface activities for PS and SPS will start at the end of the ion run, in December 2018.

  14. Beyond LS2 YETS 2021-2022 & YETS 2022-2023  13 wks for LHC & Injectors (beam to beam); equivalent to YETS 2015-2016 & 2018-2019 LS3 for LHC 30 months mainly for HL project LS3 for Injectors  12 months M. Bernardini - 15th October 2015

  15. Methodology and interfaces with EN-MEF M. Bernardini - 15th October 2015

  16. Methodology and interfaces with EN-MEF • SCHEDULING & SAFETY COORDINATION • Coordination meetings are held by the different facility’s coordinators to plan the activities during YETS and LS2 • Groups announce their activities, technical and safety aspects, interfaces are discussed • Facility coordinators gradually will refine the schedule and the organization M. Bernardini - 15th October 2015

  17. Methodology and interfaces with EN-MEF From Space Reservation (Project Phase) to ECR (Installation Phase) Space reservation • Existing situation and introduction • Reason for the change • Detailed description • Impact on other items • References ECR • Existing situation and introduction • Reason for the change • Detailed description • Impact on other items • Impact on items/systems • Impact on utilities and services • Impact on cost, schedule and performance • Impact on operational safety • Elément(s) important(s) de sécurité • Other operational safety aspects • Worksite safety • Organization • Regulatory tests • Particular risks • References M. Bernardini - 15th October 2015

  19. LS2 Project Priorities (by decreasing priorities) Realisation phase • Safety • Quality • Schedule Approval phase • Safety • Activities needed to reach 300 fb-1(Integrated Luminosity) during run3 • HL-LHC and LIU projects • Approved projects • Approved studies • Others M.

Tock – LS2 days LS2 Days 30th September2015 • LS1 Post Mortem: 1st trimester’15 • Start date: Mid December 2018; • Duration: 24 months (end 2020) • Yearly “LS2 day” as of 2015 • Activities declared in Plan by end’15 both for injectors and LHC; • March’16, definition of activities for EYETS 2016; • Mid’16, definition of activities for YETS 2017 and LS2; • Preliminary “final” validation: mid 2017.

  21. Conclusion • The YETS and EYETS are mainly dedicated to annual maintenance in the LHC and its Injectors. Nevertheless major projects as decabling project, LIU and HL-LHC will profit for these times to anticipate activities related to LS2 • The LS2 duration has been re-adjusted to allow the completion of major activities related to LIU and HL-LHC: • From 18 months to 24 (+4) months for LHC & its Injector chain • The LS2 in Injectors is mainly dedicated to the implementation of LIU project • The LS2 in LHC is mainly dedicated to major maintenances, HL-LHC and civil engineering activities in preparation of LS3 • The LS2 committee set the priorities for the LS2 Project, as well main dates and milestones M.
