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.

To produce practical amounts of fusion power on earth, heavy forms of hydrogen are joined together at high temperature with an accompanying production of heat energy. The fuel must be held at a temperature of over 100 million degrees Celsius. At these high temperatures, the electrons are detached from the nuclei of the atoms, in a state of matter called plasma.

Machine learning technique offers insight into plasma behavior

Machine learning, which lets researchers determine if two processes are causally linked without revealing how, could help stabilize the plasma within doughnut-shaped fusion devices known as tokamaks. Such learning can facilitate the avoidance of disruptions — off-normal events in tokamak plasmas that can lead to very fast loss of the stored thermal and magnetic energies and threaten the integrity of the machine.

Predhiman Kaw, founder of India’s fusion program and former PPPL physicist, is dead at age 69

Predhiman Kaw, an internationally-known plasma physicist who is considered the father of India’s nuclear fusion program, was remembered fondly by his colleagues at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) last week after they learned of Kaw’s June 19 death.  He was 69. 

PPPL-led team wins major award of time on DOE supercomputers for fusion studies in 2017

A nationwide team of researchers led by physicist C.S. Chang of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has won the use of 269.9 million supercomputer hours to complete an extreme-scale study of the complex edge region of fusion plasmas. The award was made by the DOE’s ASCR Leadership Computing Challenge (ALCC) program for 2017, supported by DOE’s Office of Science.

New engineering head Valeria Riccardo has two decades of experience on fusion experiments

Valeria Riccardo, new head of engineering at the Princeton Plasma Physics Laboratory, is a United Kingdom transplant who comes to the position with more than 20 years of experience in project management, fusion design, and analysis on two fusion devices in the U.K. that are similar to the U.S. Department of Energy’s Princeton Plasma Physics Laboratory’s National Spherical Torus Experiment-Upgrade (NSTX-U).  

Top 10 PPPL stories that you shouldn’t miss

The past year saw many firsts in experimental and theoretical research at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL). Here, in no particular order, are 10 of the Laboratory’s top findings in 2016, from the first results on the National Spherical Torus Experiment-Upgrade to a new use for Einstein’s theory of special relativity to modeling the disk that feeds the supermassive black hole at the center of our galaxy.

Valeria Riccardo

Valeria Riccardo is PPPL’s head of engineering, the largest department at PPPL. She worked for more than 20 years at the Culham Centre for Fusion Energy in Oxfordshire, England, which operates the Joint European Torus (JET) and the Mega Amp Spherical Tokamak (MAST) facility, a sister facility to PPPL. As chief engineer at the Culham Center for ve years, she was responsible for ensuring that the consequences of any design, installation and operation decision were understood.

PPPL senior physicist Wei-li Lee honored at week-long symposium

Physicists from around the world gathered at the University of California, Irvine this past summer for a symposium in honor of Wei-li Lee, a senior physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The week-long event, held from July 18-22, focused on gyrokinetic simulation — a technique Lee invented in the 1980s to model the behavior of particles within plasma, the ultrahot gas composed of electrons and atomic nuclei that fuels fusion reactions.
