Miniature Integrated Nuclear Detection System (MINDS)

Anti-terrorism efforts are getting a boost from the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL). A team led by PPPL engineer Charles Gentile has developed a Miniature Integrated Nuclear Detection System, called MINDS, which can be used to scan moving vehicles, luggage, cargo vessels, and the like for specific nuclear signatures associated with materials employed in radiological weapons.

Magnetic Reconnection Experiment (MRX)

The PPPL Magnetic Reconnection Experiment (MRX) was built to study a fundamental plasma process in a controlled laboratory environment. A plasma is a hot, ionized gas that can be confined using a magnetic field. Plasmas are often considered to be the fourth state of matter after solids, liquids, and gases, and account for more than 99 percent of the visible universe.

Fusion Power

For centuries, the way in which the sun and stars produce their energy remained a mystery to man. During the twentieth century, scientists discovered that they produce their energy through the fusion of light atoms.

E=mc2, Albert Einstein's familiar formula, provided the basis for understanding fusion. Einstein's theory that mass can be converted into energy was further explored by other physicists who discovered two practical methods for achieving this conversion.

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.
