Magnetic reconnection

Subscribe to RSS - Magnetic reconnection

Magnetic reconnection (henceforth called "reconnection") refers to the breaking and reconnecting of oppositely directed magnetic field lines in a plasma. In the process, magnetic field energy is converted to plasma kinetic and thermal energy.

Experiments at PPPL show remarkable agreement with satellite sightings

As on Earth, so in space. A four-satellite mission that is studying magnetic reconnection — the breaking apart and explosive reconnection of the magnetic field lines in plasma that occurs throughout the universe — has found key aspects of the process in space to be strikingly similar to those found in experiments at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The similarities show how the studies complement each other: The laboratory captures important global features of reconnection and the spacecraft documents local key properties as they occur.

Surprise finding: Discovering a previously unknown role for a source of magnetic fields

Magnetic forces ripple throughout the universe, from the fields surrounding planets to the gasses filling galaxies, and can be launched by a phenomenon called the Biermann battery effect. Now scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that this phenomenon may not only generate magnetic fields, but can sever them to trigger magnetic reconnection – a remarkable and surprising discovery.

No longer whistling in the dark: Scientists uncover a little-understood source of waves generated throughout the universe

Magnetic reconnection, the snapping apart and violent reconnection of magnetic field lines in plasma — the state of matter composed of free electrons and atomic nuclei — occurs throughout the universe and can whip up space storms that disrupt cell phone service and knock out power grids. Now scientists at the U.S.

Energy Secretary Rick Perry cheers on fusion energy, science education at PPPL

The Princeton Plasma Physics Laboratory’s (PPPL) mission of doing research to develop fusion as a viable source of energy is vital to the future of the planet, U.S. Energy Secretary Rick Perry said during an Aug. 9 visit. 

“It’s important not just to PPPL, not just to the DOE (Department of Energy) but to the world,” Perry told staff members during an all-hands meeting. “If we’re able to deliver fusion energy to the world, we’re able to change the world forever.” 

Powerful device to study puzzling process

A millisecond burst of light on a computer monitor signaled production of the first plasma in a powerful new device for advancing research into magnetic reconnection — a critical but little understood process that occurs throughout the universe. The first plasma, a milestone event signaling the beginning of research capabilities, was captured on camera on Sunday, March 4, at 8:13 p.m. at Jadwin Hall at Princeton University, and marked completion of the four-year construction of the device, the Facility for Laboratory Reconnection Experiment (FLARE).
