Abstract

The conceptual design study of a hadron Future Circular hadron-hadron Collider (FCC-hh) with a center-of-mass energy of the order of 100 TeV assumes using in the experimental detector the superconducting magnetic system with a central magnetic flux density of an order of 4 T. A superconducting magnet with a minimal steel yoke was proposed as an alternative to the baseline iron-free solenoids. In a present study, both designs are modeled with Cobham's program TOSCA and compared. All the main parameters are discussed.
