Researchers find unexpected electrical current that could stabilize fusion reactions

Electric current is everywhere, from powering homes to controlling the plasma that fuels fusion reactions to possibly giving rise to vast cosmic magnetic fields. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that electrical currents can form in ways not known before.

Egemen Kolemen wins 2020 Excellence in Fusion Engineering Award

Egemen Kolemen, an assistant professor in Princeton University’s Department of Mechanical and Aerospace Engineering and a physicist who focuses on solving challenges to the development of fusion facilities at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory, has won a prestigious 2020 Excellence in Fusion Engineering award presented by Fusion Power Associates (FPA).

Scientists propose a novel method for controlling fusion reactions

Scientists have found a novel way to prevent pesky magnetic bubbles in plasma from interfering with fusion reactions – delivering a potential way to improve the performance of fusion energy devices. And it comes from managing radio frequency (RF) waves to stabilize the magnetic bubbles, which can expand and create disruptions that can limit the performance of ITER, the international facility under construction in France to demonstrate the feasibility of fusion power.

First results of an upgraded experiment highlight the value of lithium for the creation of fusion energy

Lithium, the silvery metal that powers smart phones and helps treat bipolar disorders, could also play a significant role in the worldwide effort to harvest on Earth the safe, clean and virtually limitless fusion energy that powers the sun and stars. First results of the extensively upgraded Lithium Tokamak Experiment-Beta (LTX-β) at the U.S.

Doctoral graduate Yuan Shi wins 2020 Marshall N. Rosenbluth Outstanding Doctoral Thesis Award

Physicist Yuan Shi, who received his doctorate from the Princeton Program in Plasma Physics in 2018, has won the prestigious 2020 Marshall N. Rosenbluth Outstanding Doctoral Thesis Award presented by the American Physical Society (APS). The award recognizes “exceptional young scientists who have performed original doctoral thesis research of outstanding scientific quality and achievement in the area of plasma physics.”
