As part of the global effort to harness power from fusing plasma, PPPL and the University of Seville鈥檚 Plasma Science and Fusion Technology Lab worked on the computer codes, engineering and physics for a new and unique fusion reactor: the SMall Aspect Ratio Tokamak.
Como parte del esfuerzo internacional para el desarrollo de la fusi贸n nuclear como fuente de energ铆a, PPPL contribuye al desarrollo y explotaci贸n cient铆fica del SMall Aspect Ratio Tokamak, SMART, de la Universidad de Sevilla, con algunas de las simulaciones num茅ricas, ingenier铆a y f铆sica del plasma m谩s avanzadas hasta la fecha.
A new paper in Nature Machine Intelligence notes that journal articles reporting how well machine learning models solve certain kinds of equations are often overly optimistic. The researchers suggest two rules for reporting results and systemic changes to encourage clarity and accuracy in reporting.
Nominees for the award must be members of the ACS鈥檚 physical chemistry division. The winner receives the award at the meeting, gives a research presentation, and receives an honorarium. Carter is just the second person to receive this newly established award.
PPPL research scientist Lan Gao received a $2.75 million Early Career Research Program Award from the U.S. Department of Energy for her research on innovative X-ray diagnostics to develop fusion energy. Gao recently became head of PPPL鈥檚 High Energy Density Laboratory Plasmas Division of the Discovery Plasma Science Department.
Greg Hammett and Bill Dorland have been awarded the 2024 James Clerk Maxwell Prize for Plasma Physics for their pioneering work on turbulence in plasma, a key challenge in the quest for fusion energy.
PPPL scientists have observed new details of how plasma interacts with magnetic fields, potentially providing insight into the formation of enormous plasma jets that stretch between the stars.
New fusion simulations of the inside of a tokamak reveal the ideal spot for a 鈥渃ave鈥� with flowing liquid lithium is near the bottom by the center stack, as the evaporating metal particles should land in just the right spot to dissipate excess heat from the plasma.
Seasoned national laboratory scientist and leader Laura Berzak Hopkins joins PPPL as its new associate laboratory director for strategy and partnerships and deputy chief research officer.
Can plasma be sufficiently heated inside a tokamak using only microwaves? New research suggests it can! Eliminating the central ohmic heating coil normally used in tokamaks will free up much-needed space for a more compact, efficient spherical tokamak.
The thin slats of a PPPL prototype might create the ideal path for molten metal to carry away excess heat from a fusing plasma.
Researchers at the U.S. Department of Energy鈥檚 Princeton Plasma Physics Laboratory are applying their expertise in physics, chemistry and computer modeling to create the next generation of computer chips, aiming for processes and materials that will produce chips with smaller features.
PPPL physicists have developed a computer program incorporating machine learning that could help identify blobs of plasma in outer space known as plasmoids. In a novel twist, the program has been trained using simulated data.
Ravinder Bhatia, a leader and engineer with three decades of experience managing collaborative science initiatives, is the new head of ITER projects at PPPL. In this role, Bhatia oversees the design and fabrication of six diagnostic systems that PPPL is building for ITER.
A team of fusion researchers led by engineers at Princeton University and the U.S. Department of Energy鈥檚 Princeton Plasma Physics Laboratory (PPPL) have successfully deployed machine learning methods to suppress harmful edge instabilities 鈥� without sacrificing plasma performance. The research team demonstrated the highest fusion performance without the presence of edge bursts at two different fusion facilities 鈥� each with its own set of operating parameters.
The exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel鈥檚 innards as once thought, according to new research about escaping plasma particles made by researchers at the Princeton Plasma Physics Laboratory, Oak Ridge National Laboratory and ITER Organization (ITER).
PPPL scientists have developed a new theoretical model about the edge of a plasma, which can become unstable and potentially damage a fusion reactor. The model refines ideas about a critical obstacle on the path to harnessing clean energy from this fourth state of matter.
Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.
Researchers at the Department of Energy鈥檚 (DOE) Princeton Plasma Physics Laboratory (PPPL) are using artificial intelligence to perfect the design of the vessels surrounding the super-hot plasma, optimize heating methods and maintain stable control of the reaction for increasingly long periods.
