March 2015 : Outcomes of the Cost and Schedule review Findings LIU is a collection of upgrade projects with a material budget of 186 MCHF (excluding LINAC 4, ) total manpower resources of 691 FTE-yrs CERN staff and 194 FTE-yrs of “associate” labor. As a project it started around 2011 and expected completion is around 2019. Yearly expense last year was about 13 MCHF; the maximum planned yearly expense is about 42 MCHF. Comments High priority has to be given to accelerate the project progress. LIU yearly material expenditure is similar to the LHC consolidation effort (CONS). The identification of the scope as part of either LIU or CONS is not complete and also sometimes arbitrary. Scope definition of LIU is not complete for the ion program and only partially complete for SPS. There is a consistent concern by work package coordinators about availability of manpower resources. Design performance for proton beams corresponds to 85% of the HL-LHC luminosity goal with the appropriate expectation that 100% will be reached during commissioning and early operation. Equipment performance requirements should be based on reaching 100% of HL-LHC luminosity. Dispatched at the level of the LIU-machines. 2016 Chamonix recommendations: • Match the LIU beam parameter goals and the HL-LHC requirements to each other. • Secure adequate human resources to support the design, testing and 17 -19 October 2016 commissioning LIU Project - Malika Meddahi, of the large number of RF and LLRF systems for the LIU / HL-LHC Cost Giovanni Rumolo and Schedule Reviewinjectors.

2016 LIU / groups coordination Since January 2016, reflecting the LIU executing phase: LIU management meeting one group, reoccurring every 3 months, as needed. Scope of the meeting: review the planned DEPT/GROUP activities for the LIU project and cover the following questions: • Does DEPT/GROUP have all needed information from LIU (all requests? specifications? Timeline? ) • Are DEPT/GROUP preparatory activities within the expected timeline to meet the LIU installation schedule ? • Has all the LIU required work declared in PLAN? • Are the LIU EVM timeline and budget correct? • Are the DEPT/GROUP CONSolidation items links to the operation of LIU approved, in time and within specification? • Are all dependencies on other groups defined? 17 -19 October 2016 LIU / HL-LHC Cost and Schedule Review LIU Project - Malika Meddahi, Giovanni Rumolo 14

Summary • • • High priority was successfully put to accelerate the project progress – importance of Fellows, adequately supervised by experienced staff. Acknowledge support from all Department Heads and Group Leaders Need to continue on this rising PV path, with another acceleration throughout 2017 – additional corresponding resources needed (more Fellows and CERN staff) Scope definition has been clarified for LIU-ions program, and a robust baseline implemented, based on an intense study program launched in Nov. 2015 LIU proton beam parameters and HL-LHC are aligned - with the associated risks. Result of an extensive theoretical/simulation/experimental studies and anticipated installation of upgraded equipment Rigorous financial follow-up in place to monitor the project progress and steer it as needed. 17 -19 October 2016 LIU / HL-LHC Cost and Schedule Review LIU Project - Malika Meddahi, Giovanni Rumolo 34

Goals and means for the LIU Increase intensity/brightness in the injectors to match HL-LHC requirements Þ Inject H- into the PSB at 160 Me. V (replace Linac 2 with Linac 4, re-design injection into PSB) Þ Raise injection energy in PS to 2 Ge. V (increase field in PSB magnets, replace main power supply, change transfer equipment, re-design PS injection) Þ Double RF power in SPS (new 200 MHz power plant, rearrange 200 MHz system, power 2 nd 800 MHz cavity, new low-level) Þ Enable PSB/PS/SPS to accelerate and manipulate higher intensity beams (electron cloud mitigation, impedance reduction, protection devices and dumps, feedbacks, etc. ) Þ Upgrade the injectors of the ion chain (Linac 3, LEIR, PS, SPS) to produce beam parameters at the LHC injection that can meet the luminosity goal Increase injectors’ reliability and lifetime to cover HL-LHC run (until ~2035!) closely related to CONSolidation Þ Upgrade/replace ageing equipment (power supplies, magnets, RF…) Þ Improve radioprotection measures (shielding, ventilation…) 17 -19 October 2016 LIU / HL-LHC Cost and Schedule Review LIU Project - Malika Meddahi, Giovanni Rumolo 36

This includes LINAC 4, the PS booster, the PS, the SPS, as well as the heavy ion chain. The project co-ordinator will have the responsibility for the project management (WBS, technical co-ordination and integration, manpower and budget agreement with the departments as well as budget and timescale control). They will report on a regular basis to the 17 -19 October 2016 Director of Accelerators and Technology. The executive role for manpower and budget for the LIU Project - Malika Meddahi, LIU / HL-LHC Cost 37 Giovanni Rumolo projects/studies remains with the technical groups in the departments. and Schedule Review

Performance reach: evolution white area accessible • High risks HL-LHC request • PS longitudinal instabilities • SPS longitudinal losses (PS bunch rotation + intensity effects) • Medium risks • PS space charge at the limit + new beam parameters at PSB-PS transfer • SPS longitudinal instabilities • SPS transverse instabilities • SPS e-cloud (scrubbing or staged a-C coating) • Low risks • PSB brightness within margin • PS TFB for headtail and e-cloud instabilities • SPS dump and protection devices 17 -19 October 2016 LIU / HL-LHC Cost and Schedule Review LIU Project - Malika Meddahi, Giovanni Rumolo 39
