±¬×ߺÚÁÏ

The US Department of Energy's (DOE's) Princeton Plasma Physics Laboratory (PPPL) is a key contributor to ±¬×ߺÚÁÏ. PPPL provides hardware, fabrication and R&D for ±¬×ߺÚÁÏ under contract to the US Domestic Agency US ±¬×ߺÚÁÏ, a DOE Office of Science project managed by Oak Ridge National Laboratory. "It is very exciting to work on such a challenging global science project with the potential for so great a global payoff," said PPPL physicist Dave Johnson, who heads the development of diagnostic tools for US ±¬×ߺÚÁÏ.

 

The PPPL tools will provide essential data during experiments on the donut-shaped, 10-story tall ±¬×ߺÚÁÏ tokamak. PPPL also is procuring the bulk of the electrical network that will deliver steady-state, or constant, power across the sprawling 445-acre ±¬×ߺÚÁÏ site. PPPL contracts for these and other hardware components of the USD 17 billion-plus machine could total about USD 180 million, some USD 90 million of which will flow to subcontractors.

 

PPPL is conducting experimental and theoretical research relevant to ±¬×ߺÚÁÏ as well. For example, experiments planned for the National Spherical Torus Experiment (NSTX), PPPL's major fusion facility, could contribute to understanding how plasma will behave and perform in ±¬×ߺÚÁÏ. The NSTX is currently undergoing an upgrade that is doubling the strength of both its electric current and magnetic fields.
