A combination of PPPL modeling led by physicist Gerrit Kramer and DIII - D experiments has found that broadening the electric current in the center of plasma could reduce the loss of crucial elements
called alpha particles that heat the plasma and sustain fusion reactions.
One of the major goals of the ongoing space shuttle mission — Endeavour's final visit to the International Space Station — was to bestow a 7.8 - ton parting gift: an automated
particle detector
called the
Alpha Magnetic Spectrometer (AMS - 02, or, more colloquially, AMS), which was attached to the station yesterday.
