Dr. Tihiro Ohkawa of General Atomics displays a partial model of the copper shell of the Doublet I, with his innovative ‘hourglass-shape’ cross-section to enhance the plasma flow in a fusion energy device. The Doublet I device ultimately led to the development of the DIII-D tokamak, the largest operating fusion facility in the United States. Courtesy General Atomics
