WP7: Magnets

WP7 will be coordinated by CERN. Other participants are CEA, INFN, SOTON, TUDa, UTWENTE, UMIL, PSI, UNIGE, KIT, CNRS.

Objectives

The objective of this work package is to address feasibility and technology limits of the magnet and powering systems, assess technology readiness and R&D timeline. The leading topics are: (i) the value of the maximum field and free bore of the solenoids for the target, capture and cooling complex, (ii) the concept and feasibility of the fast accelerator chain, and (iii) design options for the magnets of the collider complex. We address the above topics through a combination of conceptual design work, targeted tests and specific characterization measurements. We also plan to exploit synergies with on-going developments in other fields (high magnetic field science, NMR, fusion) and programs (EU High-Field Magnets R&D, US-MDP).
