Summary

Functional 3D-printable model of the toroidal magnet system of the ATLAS detector at CERN.
Developed by the S'Cool LAB team.

More info about the ATLAS detector: ATLAS Fact Sheet.

Can also print a 3D compass to use with the model: file available here.

How I Designed This

Designed using FreeCAD, roughly in a scale 1:100 to the real detector.

Inspired by the following paper: "Assembly Concept and Technology of the ATLAS Barrel Toroid"
