Findings from an international team of scientists show that twisted magnetic fields can evolve in only so many ways, with the plasma inside them following a general rule.
The U.S. Department of Energy (DOE) announced a plan to provide $30 million for experimental research on magnetic fusion energy science at international fusion facilities known as tokamaks.
Scientists tame damaging edge instabilities in steady-state conditions required in a fusion reactor.
Combining a first laser pulse to heat up and “drill” through a plasma, and another to accelerate electrons to incredibly high energies in just tens of centimeters, scientists have nearly doubled the previous record for laser-driven particle acceleration at Berkeley Lab’s BELLA Center.
A novel experimental geometry at the Linac Coherent Light Source reveals, for the first time, how silicon responds to shocks similar to those in a planet’s core.
Spectroscopic measurements reveal that main ions flow much faster than impurities at the edge of fusion-relevant plasmas.
Surprisingly, a magnetic island does not necessarily perturb the plasma current in a dangerous way and destroy fusion performance.
ORNL neutrons investigate novel carbon capture crystals; gleaning valuable Twitter data to quickly map power outages; lightweight, heat-shielding graphite foam test yields positive results in fusion reactors; open source software scales up analysis of motor designs to run on supercomputers
Feature describes use of Magnetorotational Instability Experiment at PPPL to confirm an important mechanism involved in star formation.
Scientists at TRIUMF, the Institut de Physique Nucléaire, and Lawrence Livermore National Laboratory have for the first time accurately predicted the properties of polarized deuterium-tritium thermonuclear fusion. Their findings, described in a Nature Communications publication released today, add to our current understanding of the dynamics of nuclear fusion and may enable more accurate predictions of other thermonuclear reactions critical to nuclear science applications.
Feature describes prototype of new device that mitigates disruption of fusion plasmas faster than the most developed techniques today.
EarthCam names remote-control experiment at PPPL one of 25 most interesting Webcams of 2018.
To develop a future fusion reactor, scientists need to understand how and why plasma in fusion experiments moves into a “high-confinement mode” where particles and heat can’t escape. Scientists at the Department of Energy’s Princeton Plasma Physics Laboratory simulated the transition into that mode starting from the most basic physics principles.
Feature describes first direct sighting of a trigger for bursts of heat that can disrupt fusion reactions.
Like surfers catching ocean waves, particles within plasma can ride waves oscillating through the plasma during fusion energy experiments. Now a team of physicists led by PPPL has devised a faster method to determine how much this interaction contributes to efficiency loss in tokamaks.
New findings further the understanding of a machine known as the magnetorotational instability experiment, which is named for and brings us closer to detecting the source of the instability that causes interstellar gas and dust to collapse into celestial bodies.
Feature describes newly discovered stabilizing effect of underappreciated 1983 finding that variations in plasma temperature can influence the growth of magnetic islands that lead to disruption of fusion plasmas.
Feature summarizes and links to discoveries and breakthroughs at the Princeton Plasma Physics Laboratory in 2018, plus a profile of the knight who leads the laboratory.
