Summary

This paper documents the design, manufacturing, and testing of the subSMCC1, a subscale 2-in-1 dipole magnet developed at the Paul Scherrer Institute as part of the CHART/CERN High-Field Magnet programme. The magnet features four stress-managed Nb₃Sn common-coils with a 150 mm straight section and 22 mm bore apertures, constructed entirely from stainless-steel structural components without iron yoke or shell. The work demonstrates manufacturing feasibility and provides experimental data to inform development of full-scale high-field dipole demonstrators.

UK applicability

This superconducting magnet development is primarily relevant to UK institutions involved in high-energy physics infrastructure and accelerator technology. The findings may inform future UK participation in collaborative accelerator R&D programmes with CERN and European research facilities.

Key measures

Manufacturing process parameters, magnet training behaviour, mechanical measurements, stress management characteristics of Nb₃Sn coils

Outcomes reported

The study reports the detailed manufacturing process and test results of the first subscale stress-managed common-coils 2-in-1 dipole magnet, including training behaviour and mechanical measurements.
