Magnet Structural Materials

The high-strength alloys that hold a magnet together against its own field.

Lorentz hoop forces

Analysis

Bore-resolved stress

A high-field magnet generates immense Lorentz forces that try to blow it apart; the winding pack must be reinforced with high-strength, cryogenically-tough structural alloys and a robust case. The REBCO study resolves the stress through the winding-pack stack.

Kronos analyses bore-resolved stress against material limits; the static case is sound, with cyclic fatigue flagged as the binding magnet gate.
