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.

COLLOQUIUM: Laboratory Study of Magnetic Reconnection: Recent Discoveries on MRX

Magnetic reconnection is a phenomenon of nature in which magnetic field lines change their topology in plasma and convert magnetic energy to particles by acceleration and heating. It is one of the most fundamental processes at work in laboratory and astrophysical plasmas. Magnetic reconnection occurs everywhere: in solar flares; coronal mass ejections; the earth’s magnetosphere; in the star forming galaxies; and in plasma fusion devices.

PPPL physicists win supercomputing time to simulate key energy and astrophysical phenomena

Three teams led by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have won major blocks of time on two of the world’s most powerful supercomputers. Two of the projects seek to advance the development of nuclear fusion as a clean and abundant source of energy by improving understanding of the superhot, electrically charged plasma gas that fuels fusion reactions.

"Coordinated Solar Energetic Events", Professor Alan M. Title, Lockheed Martin Advance Technology Center/Stanford University

The Atmospheric Imaging Assembly (AIA) on the Solar Dynamic Observatory with obtains  full disk images that span the temperature range from 6000 to 20,000,000K with  arcsecond resolution and a 12 second cadence. Because of the enhanced thermal and temporal coverage and the high dynamic range available with AIA, it has been able to discovery collective behavior associated with energeti solar events that are driven by the expansion of magnetic structures.

Masaaki Yamada is a Distinguished Laboratory Research Fellow and the Head of the Magnetic Reconnection Experiment (MRX) research program. He is also a co- principal investigator of the Center for Magnetic Self-Organization in Laboratory and Astrophysical Plasmas, a Physics Frontier Center established by the National Science Foundation (NSF). 

U.S.-Japan Workshop on Magnetic Reconnection draws participants from seven countries to Princeton University

More than 70 researchers from around the world gathered at Princeton University May 23-25 for the 2012 U.S.-Japan Workshop on Magnetic Reconnection. PPPL physicist Hantao Ji chaired the international workshop, which was the twelfth since 1998 and the third to be held at Princeton. The event featured more than 55 papers, including two presented by Ji and Masaaki Yamada, who directs PPPL’s Magnetic Reconnection Experiment.
