Kees Bol, a scientist on Project Matterhorn, PDX and numerous experiments, dies at 90

Kees Bol, a physicist who played a part in the history of the Laboratory first as part of Project Matterhorn and then through roles in several crucial experiments at PPPL for three decades, died at his home in Skillman, New Jersey, on Aug. 8 at age 90.

Former colleagues of Bol, whose first name is pronounced “Case,” remembered his quiet professionalism and his role as a mentor in a career that spanned the beginning of the fusion program at PPPL through the 1980s.

A.J. Stewart Smith to step down as Princeton University vice president for PPPL in 2016

As a young man, A.J. Stewart “Stew” Smith won the Canadian National Lacrosse Championship as a member of a powerful Vancouver, British Columbia, club team. That early success and love of teamwork foreshadowed an illustrious career in which Smith has played leading roles as an educator, administrator and particle physicist. Now, after nearly 50 years on the faculty and staff of Princeton University, Smith is stepping down next February from his current post as the University’s initial vice president for the Princeton Plasma Physics Laboratory (PPPL).

Scientists propose an enhanced new model of the source of a mysterious barrier to fusion known as the “density limit”

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a detailed model of the source of a puzzling limitation on fusion reactions. The findings, published in June in Physics of Plasmas, complete and confirm previous PPPL research and could lead to steps to overcome the barrier if the model proves consistent with experimental data. “We used to have correlation,” said physicist David Gates, first author of the paper. “Now we believe we have causation.” This work was supported by the DOE Office of Science.

X marks the spot: Researchers confirm novel method for controlling plasma rotation to improve fusion performance

Rotation is key to the performance of salad spinners, toy tops, and centrifuges, but recent research suggests a way to harness rotation for the future of mankind's energy supply. In papers published in Physics of Plasmas in May and Physical Review Letters this month, Timothy Stoltzfus-Dueck, a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), demonstrated a novel method that scientists can use to manipulate the intrinsic – or self-generated – rotation of hot, charged plasma gas within fusion facilities called tokamaks.
