R.G. 5 LIU status - 6/03/2012 Achievements in 2011 Formal organization of the LIU project: Nomination of additional members of the project team (Project Safety Officer and responsible for ions) Adjustment of project scope with transfer of activities from Linac4 (H - injection the PSB and all PSB-related tasks) and Consolidation Definition of Work Breakdown Structure, most of Work Units, budget codes and budget needs. Scientific/technical achievements: Analysis of injectors’ potential using MDs and simulations Refinement of the required actions on equipment (upgrades and replacement) with reviews (e-cloud, 160 MeV injection, beam instrumentation…) Workshop with HL-LHC project in view of converging on beam characteristics.

R.G. 7 LIU status - 6/03/2012 Goals for 2012 and 2013 Scientific/technical goals: Analysis of injectors’ potential using MDs and simulations in view of stating the final project goals in agreement with HL-LHC at the end of Specification of actions on equipment (upgrades and replacement) with reviews (e-cloud, …) Publication of Design Report in 2013, Preparation of future upgrades during LS1.5(?) and LS2. Management goals: EVM follow-up of the PSB upgrade. Specification of cost to completion at the beginning of Start of EVM follow-up of PS and SPS upgrades in 2013.

R.G. 8 LIU status - 6/03/2012 Main work on the accelerators during LS1 PSB: Construction of H - injection equipment (magnets, pulsers, vacuum chambers and valves…) Cabling for H - injection equipment Replacement of beam dump and crane Preparation for new main power converter (new building) Upgrade of beam instrumentation (new orbit measurement system and devices for H - injection) New LLRF and prototype RF cavity PS: Radiation shielding on Road Goward and above septum 16 Finemet-based longitudinal damper New beam instrumentation (fast BLMs, study of IPMs) Design/order of power converters for low energy correctors SPS: Preparation for upgrade of 200 MHz RF system Installation of aC coated vacuum chambers in 2-4 half-cells Upgrade of transverse damper Installation of wide band transverse feedback Beam instrumentation (BFCT upgrade, BGI development, new diamond BLMs, prototype mechanics for new wire scanner) Cabling! Cabling of fibre optic backbone and one LSS + some coaxial cables!

R.G. 15 LIU status - 6/03/2012 Additional issues (1/2) Will there be an LS1.5 at ~end of 2016? Very useful for (1) making use of the investment in Linac4, (2) reducing risk (stop of Linac2) and (3) minimizing workload and time/risks for commissioning after LS2 (staging of the upgrades) Necessitates resources for work on the PSB during LS1 and preparation of cabling with Linac4. Need for planning LS2: at least 12 months for hardware installation + n months for hardware and beam commissioning. => no beam from the injectors during ~18 months.

R.G. 16 LIU status - 6/03/2012 Additional issues (2/2) Letter of support to the DOE for continuation of the development by US-LARP of a wideband transverse sytem in the SPS. Organization of publications in the Accelerator Sector Present situation is not satisfying (no easy means to identify the publications on LIU at least) Little progress from my side (lack of time) except for a draft proposal prepared with Malika. Suggestion to put someone in charge from the Project Support Office for refining a proposal, proposing it to the ATSMB and following its implementation
