The study of plasma, a partially-ionized gas that is electrically conductive and able to be confined within a magnetic field, and how it releases energy.

A collaboration bears fruit as W7-X celebrates first research plasma

Scientists from the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and other national laboratories joined colleagues from around the world at the celebration for the first plasma of the Wendelstein 7-X (W7-X) stellarator at the Max Planck Institute in Greifswald, Germany. The Dec. 10 event heralded the start of the largest and most advanced fusion experiment of its kind in the world and could yield promising solutions to some of the most difficult challenges in developing fusion energy.

Schweickhard “Schwick” von Goeler, inventor of groundbreaking diagnostics used to analyze fusion experiments worldwide, dies at 84

Schweickhard “Schwick” von Goeler, an award-winning physicist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) for more than 35 years and the inventor of numerous X-ray diagnostics used in fusion experiments worldwide, died of leukemia on Dec. 6 in Springfield, Massachusetts. He was 84.

Bernard named communications director of the Princeton Plasma Physics Laboratory

Larry Bernard, a proven developer of strategic communications programs, has been named director of communications for the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), effective December 14. PPPL is the nation’s leading center for the exploration of plasma science and magnetic fusion energy.

PPPL researcher maps magnetic fields in first physics experiment on W7-X

As excitement builds around the first plasma, scheduled for December, on the Wendelstein 7-X (W7-X) experiment in Greifswald, Germany, PPPL physicist Sam Lazerson can boast that he has already achieved results.

Lazerson, who has been working at the site since March, mapped the structure of the magnetic field, proving that the main magnet system is working as intended.  This was achieved using the trim coils that PPPL designed and had built in the United States. He presented his research at the APS Division of Plasma Physics Conference in Savannah, Georgia, on Nov. 18. 

PPPL physicists propose new plasma-based method to treat radioactive waste

Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are proposing a new way to process nuclear waste that uses a plasma-based centrifuge. Known as plasma mass filtering, the new mass separation techniques would supplement chemical techniques.  It is hoped that this combined approach would reduce both the cost of nuclear waste disposal and the amount of byproducts produced during the process.  This work was supported by PPPL's Laboratory Directed Research and Development Program.
