A commercially viable deuterium-tritium fusion device needs a blanket to shield against neutrons and produce tritium. Columbia’s research in this area is focused on extracting tritium from the blanket and modeling how conducting blanket concepts interact with plasma dynamics.

Design against off-normal events is an essential part of fusion energy research. The rapid quench of the tokamak plasma (called a 'disruption') releases a burst of energy into the reactor vessel that must be controlled. Research involves designing systems and techniques to manage this energy release in a benign manner.
