Summary
This paper describes the 3-D magnetic and mechanical design of coil ends for CERN's racetrack model magnet (RMM), a test magnet intended to demonstrate the feasibility of achieving 16 T nominal field in a compact 50 mm bore. The authors present an engineering analysis of tie rod and end-plate structures under various loading configurations, evaluating different materials and friction conditions to optimise the design. A final design solution is proposed that balances magnetic performance criteria (lower peak field in ends relative to the straight section) with mechanical requirements (adequate force containment).
Key measures
Magnetic field strength (Tesla), bore diameter (mm), peak field distribution in magnet ends versus straight section, electromagnetic force containment, tie rod and end-plate design parameters, material properties, friction effects
Outcomes reported
The study presents a 3-D magnetic and mechanical design analysis for coil ends of the racetrack model magnet (RMM), demonstrating the feasibility of achieving a nominal magnetic field of 16 T in a 50 mm bore with controlled peak field distribution and contained electromagnetic forces.
