Description
The High Luminosity LHC (HL-LHC) Project requires changing or modifying numerous magnet circuits in the High Luminosity insertions (Point 1 and Point 5) of the collider. The higher peak field, higher current and larger magnetic energy, as well as the necessity to displace the power converter far from radiation areas, with use of superconducting links, make the system more complex and technically very challenging. “Mr. HL-LHC Circuit”, Felix Rodriguez Mateos, has been appointed to steer the optimization and ensure consistency of the whole system.
The goal of this review is to examine the baseline choices and open variants with respect to the following aspects:
- Circuit Topology
- Magnet and Circuit Protection
- Circuit Integration
- Operation
- Voltage Withstand Levels
- Plan and Schedule
Review panel: Akira Yamamoto (CERN & KEK, Chair), Guram Chlachidze (FERMILAB), Arnaud Devred (ITER), Chen-Yu Gung (ITER), Davide Tommasini (CERN), Rudiger Schmidt (CERN), Markus Zerlauth (CERN, Sc. Secretary).

The review is scheduled on 21st to 23rd March 2016 with the close-out on 23rd March at CERN.
