Description
The design of superconducting magnet for a high-energy Muon Collider continues to push the limits of present magnet technology, requiring new ideas that go beyond those encountered in conventional LTS systems. In this context, we are exploring a block-coil dipole concept specifically tailored to the unconventional boundary conditions imposed by muon physics: intense radiation from muon decay, tight geometric constraints and the need for both large aperture and ultra-high field. The design targets 16 T in a 140 mm bore, featuring an innovative stacked REBCO cable orientation and an unconventional end-winding concept.
In this contribution, we present the current status of our conceptual design, developed through a finite-element model implemented in ANSYS APDL. We focus on electromagnetic analysis, aimed to optimize the geometric field quality while maintaining the required operating margin on the load line and accounting of the impact of persistent currents due to the magnetization effects. Furthermore, we discuss our mechanical modelling approach based on a stress-management concept designed to meet the new mechanical paradigms introduced by HTS cable technology. We then present the corresponding mechanical analysis results, including the stress distribution induced by cool-down and energization.
