3-D printed model of the Mu2e solenoid

This model of the Mu2e solenoids was made on a 3-D printer at the University of Virginia. The Mu2e solenoids will form a continuous magnetic channel that captures pions from a production target, form a secondary muon beam and provide a constant field for momentum analysis of 100-MeV electrons. The magnetic field varies from nearly 5 Tesla (at the far right) to 1 Tesla (at the far left). The Mu2e tracker and calorimeter reside inside the solenoid at the far left. 3-D printing technology makes it possible to fabricate detailed models for a fraction of the cost of a traditional scale model.
