Two major new components power the National Spherical Torus Experiment-Upgrade: A widened center stack that doubles the magnetic field strength and plasma current and quintuples the length of fusion experiments, and a second neutral beam injector that doubles the tokamak’s heating power. Taken together, the new parts boost the NSTX-U operating conditions closer to those that will be found in a commercial fusion power plant.
Constructing the National Spherical Torus Experiment Upgrade took years of detailed planning and oversight. The team in charge brought decades of experience to the task, working together to make the $94 million upgrade a reality.
PPPL collaborator Lenore Rasmussen, the sole proprietor of her Princeton-based, startup firm, Ras Labs, LLC, has the gift of serendipity. Two disparate life experiences sparked the polymer chemist’s interest in the development of electro-responsive “smart materials” — electrically-driven polymers that are strong and durable enough to act as artificial muscles in prosthetic devices and robotics.
