A system of antennas similar to those that astrophysicists use to study radio emissions from stars and galaxies will help shed light on fusion experiments at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL).
The tools used by researchers to assess the characteristics of superheated and electrically charged gases known as plasmas.
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.
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.
In a rare transition, engineer Russ Feder has stepped into a management job that a distinguished physicist last held. Feder leads PPPL’s development of all diagnostic tools for US ITER, which manages U.S. contributions to the international ITER experiment, succeeding physicist Dave Johnson in that role. “I’m excited to keep the momentum going and proud to be part of our strong team,” Feder said. “I also recognize the tough challenges of the job and will need the help of our team and the U.S. diagnostics community to be successful.”
Some 135 researchers, graduate students, and staff members from PPPL joined 1,500 research scientists from around the world at the 56th annual meeting of the American Physical Society Division of Plasma Physics Conference from Oct. 27 to Oct. 31 in New Orleans. Topics in the sessions ranged from waves in plasma to the physics of ITER, the international physics experiment in Cadarache, France; to women in plasma physics. Dozens of PPPL scientists presented the results of their cutting-edge research into magnetic fusion and plasma science.
This lecture reviews the development of x-ray spectroscopy at PPPL, which began in the 1970’s on the ST (Symmetric Tokamak) and has had a significant impact on the magnetic fusion research program worldwide. Several important physics parameters can be measured with these techniques.
