PPPL scientist uncovers physics behind plasma-etching process

Physicist Igor Kaganovich at the Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and collaborators have uncovered some of the physics that make possible the etching of silicon computer chips, which power cell phones, computers, and a huge range of electronic devices. Specifically, the team found how electrically charged gas known as plasma makes the etching process more effective than it would otherwise be.

PPPL physicist uncovers clues to mechanism behind magnetic reconnection

Physicist Fatima Ebrahimi at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has published a paper showing that magnetic reconnection — the process in which magnetic field lines snap together and release energy — can be triggered by motion in nearby magnetic fields. By running computer simulations, Ebrahimi gathered evidence indicating that the wiggling of atomic particles and magnetic fields within electrically charged gas known as plasma can spark the onset of reconnection, a process that, when it occurs on the sun, can spew plasma into space.

Scientists develop a path toward improved high-energy accelerators

Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), in collaboration with researchers in South Korea and Germany, have developed a theoretical framework for improving the stability and intensity of particle accelerator beams. Scientists use the high-energy beams, which must be stable and intense to work effectively, to unlock the ultimate structure of matter.  Physicians use medical accelerators to produce beams that can zap cancer cells.

PPPL and Max Planck physicists confirm the precision of magnetic fields in the most advanced stellarator in the world

Physicist Sam Lazerson of the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has teamed with German scientists to confirm that the Wendelstein 7-X (W7-X) fusion energy device called a stellarator in Greifswald, Germany, produces high-quality magnetic fields that are consistent with their complex design.

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.
