“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.”

LIU Project status

TE

EPC

  • RCS option studied and rejected.
  • LIU project approved in the 24th of august LMC.
  • Official date for project start on 1st 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.

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.

TE

EPC

  • 420m2 required, only 190m2 available in bdg. 271 ground floor.
  • Only 200kg/m2 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.

  • The linear stage can handle the new rated current.
  • The capacitor bank size needs to be increased.

  • Optimization still need to be done: pulsing converters and keep existing magnets, BT.BHZ10 magnet design, 2GeV quadrupoles optic, reuse of some converters or spares
