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).
