Physicist Fatima Ebrahimi conducts computer simulations that indicate the efficiency of an innovative fusion start-up technique

Physicist Fatima Ebrahimi at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection (CHI), could also benefit tokamaks that use superconducting magnets. The research was published in March 2016, in Nuclear Fusion, and was supported by the DOE's Office of Science.

Physicist Egemen Kolemen awarded funding from the U.S. Department of Energy's Early Career Research Program

Physicist Egemen Kolemen, who has dual appointments at both Princeton University and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), has been awarded funding from the DOE's Early Career Research Program. The grant, covering five years and totaling almost $850,000, will support research on how to monitor and control instabilities within fusion machines known as tokamaks.

Physicist Tyler Abrams models lithium erosion in tokamaks

The world of fusion energy is a world of extremes. For instance, the center of the ultrahot plasma contained within the walls of doughnut-shaped fusion machines known as tokamaks can reach temperatures well above the 15 million degrees Celsius core of the sun. And even though the portion of the plasma closer to the tokamak's inner walls is 10 to 20 times cooler, it still has enough energy to erode the layer of liquid lithium that may be used to coat components that face the plasma in future tokamaks.

Hunting for Big Bang neutrinos that could provide fresh insight on the origin of the universe

Big Bang neutrinos are believed to be everywhere in the universe but have never been seen.  The expansion of the universe has stretched them and they are thought to be billions of times colder than neutrinos that stream from the sun.  As the oldest known witnesses or “relics” of the early universe, they could shed new light on the birth of the cosmos if scientists could pin them down. That’s a tall order since these ghostly particles can speed through planets as if they were empty space.

PPPL engineers design and build state-of-the-art controller for AC to DC converter that manages plasma in upgraded fusion machine

The electric current that powers fusion experiments requires superb control. Without it, the magnetic coils the current drives cannot contain and shape the plasma that fuels experiments in doughnut-shaped tokamaks correctly.

PPPL inventors win award for device that creates medical isotope vital for diagnosing diseases

Charles Gentile, an engineer at PPPL, and fellow inventors George Ascione and Adam Cohen won third prize at Princeton University Keller Center’s 11th Annual Innovation Forum on Feb. 24 for their invention of an on-demand method to create a badly needed isotope used routinely in medical imaging for diagnosis.
