1. Booster and PS LIU workunits EPC Project Meeting 06-09-2011 Serge Pittet TEEPC

2. The LIU Project The LHC Injectors Upgrade should plan for delivering reliably to the LHC the beams required for reaching the goals of the HL-LHC. This includes LINAC4, the PS booster, the PS, the SPS, as well as the heavy ion chain. 06/09/2011TE-EPC - Serge Pittet2 TEEPC D. NisbetD. Nisbet (inj.) S. Pittet Project leader R. Garoby Linac4 M.

3. LIU Project status RCS option studied and rejected. LIU project approved in the 24 th of august LMC. Official date for project start on 1 st of September 2011. TDR to be completed by the end of 2011. Startup of upgraded machines at the end of LS2 (2017?). Some budget codes already funded. WBS and WUs will soon be transferred in APT. 06/09/2011TE-EPC - Serge Pittet3 TEEPC

7. POPS based Baseline 06/09/2011TE-EPC - Serge Pittet7 TEEPC Benefits Overall voltage available increases and would allow a reduction of the RMS current using a faster ramping. The capacitor bank totally absorbs the peak power on the 18kV network. Meyrin SVC would then become optional. Spare sharing between MPS A and B and eventually with POPS. Only a few new cables needed between the reference magnet (BCER) and the MPS. New B-field regulation to minimize eddy currents and saturation effects impact at higher current and acceleration rate. Drawbacks Cost estimation 14MCHF using POPS module.

8. Layout of MPS new building 06/09/2011TE-EPC - Serge Pittet8 TEEPC New MPSB (2 GeV) (26m x 16m) TT6 420m 2 required, only 190m 2 available in bdg. 271 ground floor. Only 200kg/m 2 allowed in bdg. 271 first floor. No space left in bdg. 361. With this new building: We can install and commission during Booster operation. We have a backup power supply during the first years. Easy connection to existing cables and cooling services.

9. LIU-PSB 5.2 – ALG1&2 The linear stage can handle the new rated current. The capacitor bank size needs to be increased. 06/09/2011TE-EPC - Serge Pittet9 TEEPC Perform ALG1&2 upgrade Holderdavid.nisbet@cern.ch Budget code99327 (not active yet) Budget200kCHF unit(s)4 DeadlineLS2
