PPPL scientists deliver new high-resolution diagnostic to national laser facility

Scientists from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have built and delivered a high-resolution X-ray spectrometer for the largest and most powerful laser facility in the world. The diagnostic, installed on the National Ignition Facility (NIF) at the DOE’s Lawrence Livermore National Laboratory, will analyze and record data from high-energy density experiments created by firing NIF’s 192 lasers at tiny pellets of fuel. Such experiments are relevant to projects that include the U.S. Stockpile Stewardship Program, which maintains the U.S.

PPPL honors Grierson and Greenough for distinguished research and engineering achievements

A breakthrough in the development of fusion diagnostics and the creative use of radio frequency waves to heat the plasma that fuels fusion reactions earned the 2017 outstanding research and engineering awards from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). Physicist Brian Grierson and engineer Nevell Greenough received the honors from PPPL Interim Director Richard Hawryluk at a ceremony November 7 for their exceptional achievements.

Physicists propose new way to stabilize next-generation fusion plasmas

A key issue for next-generation fusion reactors is the possible impact of many unstable Alfvén eigenmodes, wave-like disturbances produced by the fusion reactions that ripple through the plasma in doughnut-shaped fusion facilities called “tokamaks.” Deuterium and tritium fuel react when heated to temperatures near 100 million degrees Celsius, producing high-energy helium ions called alpha particles that heat the plasma and sustain the fusion reactions.

PPPL delivers new key components to help power a fusion energy experiment

Fusion power, which lights the sun and stars, requires temperatures of millions of degrees to fuse the particles inside plasma, a soup of charged gas that fuels fusion reactions. Here on Earth, scientists developing fusion as a safe, clean and abundant source of energy must produce temperatures hotter than the core of the sun in doughnut-shaped facilities called tokamaks. Much of the power needed to reach these temperatures comes from high-energy beams that physicists pump into the plasma through devices known as neutral beam injectors.

Simulation demonstrates how exposure to plasma makes carbon nanotubes grow

At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), research performed with collaborators from Princeton University and the Institute for Advanced Computational Science at the State University of New York at Stony Brook has shown how plasma causes exceptionally strong, microscopic structures known as carbon nanotubes to grow. Such tubes, measured in billionths of a meter, are found in everything from electrodes to dental implants and have many advantageous properties.
