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 Multi-Point Thomson Scattering (MPTS) diagnostic system has been providing time dependent Te and ne profile measurements on NSTX for ten years.
Low-temperature plasma, a rapidly expanding source of innovation in fields ranging from electronics to health care to space exploration, is a highly complex state of matter. So complex that the Princeton Plasma Physics Laboratory (PPPL) has teamed with Princeton University to become home to a collaborative facility open to researchers from across the country to advance the understanding and control of this dynamic physical state.
Scientists produce the first laboratory measurement of the precursors to shock waves driven by solar flares.
Leadership of laboratory experiments that bring astrophysical processes down to Earth has won physicist Will Fox the 2019 Thomas H. Stix Award. The American Physical Society (APS) honor, which recognizes outstanding early career contributions to plasma physics, was established in 2013 in the name of the late Thomas H. Stix, the pioneering plasma researcher who founded the graduate plasma physics program at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL).
Original and seminal experiments
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.
Experiment opens the door to studying cosmic shocks in greater detail than is possible with spacecraft.
The Matter-Radiation Interactions in Extremes (MaRIE) project will provide capability that will address the control of performance and production of materials at the mesoscale. MaRIE will characterize the behavior of interfaces, defects, and microstructure between the spatial scales of atomic structures and those of the engineering continuum where there is a current capability gap.
Two U.S. Department of Energy (DOE) laboratories working on very different types of fusion experiments have begun a novel collaboration. Under the arrangement, the DOE’s Princeton Plasma Physics Laboratory (PPPL) will design a diagnostic system to provide high-resolution analysis of research on the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). This work is supported by the DOE Office of Science and LLNL.
Intense laser and particle beams can be focused down to intensities in excess of 10^23 W/cm^2. Similar intensities are also present in extreme astrophysical scenarios. Under these conditions, the interaction of these intense beams and fields with plasmas is very rich, permeated by collective processes, relativistic nonlinearities and strong field physics. The complexity of these scenarios can only be grasped resorting to large scale numerical simulations. Advanced multi-scale models combined with massively parallel high performance computing are driving new discoveries.
