Lithium Tokamak Experiment (LTX)

The Lithium Tokamak Experiment (LTX) produced its first plasma in September, 2008. The new device will continue the promising, innovative work started on CDX-U in 2000, involving the use of pure lithium metal on surfaces facing or contacting the plasma. PPPL researchers believe that LTX may herald a new regime of plasma performance with improved stability, lower impurity levels, better particle and temperature control, and more efficient operation.

National Spherical Torus Experiment (NSTX)

The National Spherical Torus Experiment (NSTX) at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) is yielding research results that may open an attractive path towards developing fusion energy as an abundant, safe, affordable and environmentally sound means of generating electricity.

The NSTX device is exploring a novel structure for the magnetic field used to contain the hot ionized gas, called plasma, the fuel for the production of fusion energy.

ITER Experiment Brochure

ITER is a large international fusion experiment aimed at demonstrating the scientific and technological feasibility of fusion energy. ITER (Latin for “the way”) will play a critical role advancing the worldwide availability of energy from fusion — the power source of the sun and the stars.
