Fusion reactor design

The design of devices that use powerful magnetic fields to control plasma so fusion can take place. The most widely used magnetic confinement device is the tokamak, followed by the stellarator.

COLLOQUIUM: Achieving 10MW Fusion Power in TFTR: a Retrospective

"The Tokamak Fusion Test Reactor (TFTR) operated at the Princeton Plasma Physics Laboratory (PPPL) from 1982 to 1997. TFTR set a number of world records, including a plasma temperature of 510 million degrees centigrade -- the highest ever produced in a laboratory, and well beyond the 100 million degrees required for commercial fusion. In addition to meeting its physics objectives, TFTR achieved all of its hardware design goals, thus making substantial contributions in many areas of fusion technology development.

COLLOQUIUM: Industrialization of Nb3Sn conductor

Superconducting magnets are enabling tools for scientific research, and are also a vital component of our health care system.  Advances in magnet technology are strongly linked to advances in superconductor performance.  While particle accelerators for high energy physics and tokomaks for fusion are two prominent examples of research applications of superconductors, the demand for superconductors for these “big science” projects is neither steady nor certain.  As a result, it is often not a straight path to commercial success for new superconducting materials.

COLLOQUIUM: Smaller & Sooner: The ARC Pilot Design for Fusion Development

A new generation of superconducting (SC) tapes puts within reach loss-free magnetic fields with B > 20 Tesla on coil, doubling the field allowed by the present SC technology.  The tapes can also provide demountable SC toroidal field coils.  The ARC FNSF/Pilot design study explores how access to such technology would be a “game-changer” for small, robust tokamak reactors.

COLLOQUIUM: Large Scale Superconducting Magnets for Variety of Applications

Over the past several decades the U. S. magnetic confinement fusion program, working in collaboration with international partners, has developed superconductor and superconducting magnet technology to a very advanced level. These developments have been made using the low temperature superconductors (LTS) NbTi and Nb3Sn. The now operating Large Hadron Collider at CERN has demonstrated the scientific success of NbTi technology on a very large scale.

“Rip” Perkins, pioneering PPPL physicist and a design leader for ITER, dies at 80

Francis “Rip” William Perkins Jr., a pioneering plasma physicist whose contributions to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) ranged from seminal advances in fusion energy and astrophysical research to the education of a generation of scientists, died on July 26 in Boulder, Colo. He was 80 and had long battled Parkinson’s disease.

COLLOQUIUM: Superconductors for Fusion for Next Ten Years

Present fusion devices requiring superconductors all use Nb-Ti or Nb3Sn. But conductors for high magnetic field use are undergoing a considerable development at present, especially devices that may be made with the high temperature cuprate superconductors, REBa2Cu3Ox, Bi2Sr2CaCu2O8+x and (Bi,Pb)2Sr2Ca2Cu3O10. We at the magnet lab have used these conductors to generate magnetic fields over 35 Tesla in small insert coils and an all superconducting 32 Tesla magnet for users of the magnet lab is now in construction.
