Description

HL-LHC is in the final stage of design and prototyping: all technologies for the hardware upgrade must be fully proven by beginning of 2017. This review covers the 11T dipole, planned to substitute the LHC dipole cryo-magnets in the Dispersion Suppressor, with a new unit producing the same integrated field, requiring a bore field in the range of 11 T, and an integrated by-pass for a collimator. Previous technical reviews addressed the engineering concepts, and cost and schedule (within the overall scope of HL-LHC).

The scope of this review is to examine:

  • Magnet design status, with special attention to the cold mass, its cryostat and electrical, hydraulic, mechanical, vacuum interfaces and integration in the LHC continuous cryostat and LHC arc circuit;
  • By-pass and collimator design;
  • Results of model magnets;
  • Status of prototype magnets;
  • Conductor performance, procurement status and plans; 
  • Status of production tooling, finalization of design and procurement; 
  • Components procurement, status and plans;
  • Test plan, QA/QC, and safety aspects;
  • Production schedule and global plan to installation (including constraints given by LS2).

Review panel: Akira Yamamoto (KEK-CERN, Chair), Giorgio Apollinari (Fermilab), Arnaud Devred (ITER), Pasquale Fabbricatore (INFN), Joe Minervini (MIT), Pierre Vedrine (CEA).

The review is scheduled on 6th to 8th April 2016, at CERN.
