The U.S. Department of Energy (DOE) has awarded $21 million in funding for collaborators to install and operate new scientific instruments on the flagship fusion facility at the DOE’s Princeton Plasma Physics Laboratory (PPPL).
The U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has launched engineering design activity on several plasma diagnostic systems for ITER, the international fusion experiment now under construction in France. When installed on the ITER tokamak, these diagnostics will allow scientists to make measurements needed to understand the behavior of the hot super-charged gas called plasma under fusion conditions in which ITER will produce for the first time a self-sustaining or burning plasma.
A key obstacle to controlling on Earth the fusion that powers the sun and stars is leakage of energy and particles from plasma, the hot, charged state of matter composed of free electrons and atomic nuclei that fuels fusion reactions. At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), physicists have been focusing on validating computer simulations that forecast energy losses caused by turbulent transport during fusion experiments.
Scientists have created a novel method for measuring the stability of a soup of ultra-hot and electrically charged atomic particles, or plasma, in fusion facilities called “tokamaks.” Involving an innovative use of a mathematical tool, the method might lead to a technique for stabilizing plasma and making fusion reactions more efficient.
Steven Cowley, a theoretical physicist and international authority on fusion energy, became the seventh Director of the Princeton Plasma Physics Laboratory (PPPL) on July 1 and will be Princeton professor of astrophysical sciences on September 1.
Any solid surface immersed within a plasma, including those in satellite engines and fusion reactors, is surrounded by a layer of electrical charge that determines the interaction between the surface and the plasma. Understanding the nature of this contact, which can affect the performance of the devices, often hinges on understanding how electrical charge is distributed around the surface. Now, recent research by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) indicates a way to more accurately measure these electrical properties.
A team of scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has won a DOE Office of Science award to develop new X-ray diagnostics for WEST — the Tungsten (W) Environment in Steady-state Tokamak — in Cadarache, France. The three-year, $1-million award will support construction of two new devices at PPPL, plus collaboration with French scientists and deployment of a post-doctoral researcher to test the installed devices at CAE Laboratories, the home of the WEST facility.
