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.
Mark your calendar and prepare to have some fun at The Princeton Plasma Physics Lab's Open House on June 1 from 9 a.m. to 4 p.m. when the Laboratory will open its doors for the public to see the National Spherical Torus Experiment and other research experiments. Come take a self-guided tour, take part in hands-on activities, watch demonstrations. Plans also include a moon rocks display from NASA, lectures on fusion by PPPL Director Stewart Prager, a cryogenics show, firefighting demonstrations and numerous other activities as well as refreshments and give-aways.
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.
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.
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).
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.
