Your task: Take apart, decontaminate, refurbish, relocate, reassemble, realign and reinstall a 75-ton neutral beam box that will add a second beam box to the National Spherical Torus Experiment-Upgrade (NSTX-U) and double the experiment’s heating power. Oh, and while you’re at it, hoist the two-story tall box over a 22-foot wall.
The U.S. Department of Energy has bestowed many hours of access to scientists at the Center for Edge Physics Simulation (EPSI), led by C.S. Chang, a physicist at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory. The highly competitive award allows 270 million core hours on two powerful supercomputers that will enable researchers to continue staging complex simulations of how charged particles behave in the tokamak edge. The award was the second highest in the INCITE program.
Investigating long-term solutions to the world's energy needs and investing in sustainable technologies are crucial as the climate crisis comes into focus, a set of experts cautioned at Princeton University on Nov. 14.
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.
When scientists at the Korea Supercomputing Tokamak Advanced Research (KSTAR) facility needed a crucial new component, they turned to PPPL engineer Bob Ellis. His task: Design a water-cooled fixed mirror that can withstand high heat loads for up to 300 seconds while directing microwaves beamed from launchers to heat the plasma that fuels fusion reactions.
