Considerations on a Cost Model for High-Field Dipole Arc Magnets for FCC

Abstract

In the frame of the European circular collider, a conceptual design study for a post-Large Hadron Collider research infrastructure based on an energy-frontier 100 TeV circular hadron collider, a cost model for the dipole arc magnets is being developed. This paper presents an analysis of the different cost drivers for these magnets, in particular for what concerns magnet aperture, the nature and extent of grading, margin and operating temperature.
