in 2018 bluegrass supported general atomics by cutting a ¼ scale mockup of the iter solenoid constructed by wrapping 288 individual stainless steel bars with copper conductor and coiling the resulting “superconductor” into a ring 3 ft tall x 2 ½ ft wide. the heart of the iter tokamak, a solenoid is used to magnetically confine a plasma of reactive charged particles into a hollow doughnut-shaped container. the ring of stainless steel and copper was segmented into 4 pieces sized for shipment to another facility for analysis.
