propel the craft forward. Current
space-proven plasma
thrusters use electric fields to
propel the particles.
The new concept would accelerate
the particles using
magnetic reconnection, a process
found throughout the universe,
including the surface of
the sun, in which magnetic
field lines converge, suddenly
separate, and then join again,
producing lots of energy.
PPPL scientists have designed
a new type of magnet
that could aid devices ranging
from doughnut-shaped fusion
facilities known as tokamaks to
medical machines that create
detailed pictures of the human
body.
Tokamaks rely on a central
electromagnet known as a solenoid
to create electrical currents
and magnetic fields that
