Neilson visits German stellarator to pave way for U.S. researchers

Hutch Neilson, PPPL’s head of Advanced Projects, is saying “auf wiedersehen” to the Lab for the next nine months as he travels to Greifswald, Germany, where he will be paving the way for future U.S. researchers to participate on the Wendelstein 7-X (W7-X) program as the experiment begins preparing for operations next year.

David Gates, a principal research physicist and the stellarator physics leader at PPPL, will be serving as Interim Head of Advanced Projects in Neilson’s absence.

“Rip” Perkins, pioneering PPPL physicist and a design leader for ITER, dies at 80

Francis “Rip” William Perkins Jr., a pioneering plasma physicist whose contributions to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) ranged from seminal advances in fusion energy and astrophysical research to the education of a generation of scientists, died on July 26 in Boulder, Colo. He was 80 and had long battled Parkinson’s disease.

Experts assemble at PPPL to discuss mitigation of tokamak disruptions

Some 35 physicists from around the world gathered at PPPL last week for the second annual Laboratory-led workshop on improving ways to predict and mitigate disruptions in tokamaks. Avoiding or mitigating such disruptions, which occur when heat or electric current are suddenly reduced during fusion experiments, will be crucial for ITER the international experiment under construction in France to demonstrate the feasibility of fusion power.

PPPL’s dynamic diagnostic duo

Kenneth Hill and Manfred Bitter are scientific pioneers who have collaborated seamlessly for more than 35 years. Together they have revolutionized a key instrument in the quest to harness fusion energy — a device called an X-ray crystal spectrometer that is used around the world to reveal strikingly detailed information about the hot, charged plasma gas that fuels fusion reactions.
