Not exact matches
In the United States, government - funded
labs are simultaneously pushing two tracks — inertial
fusion and
magnetic confinement
fusion — but neither with the vigor needed to advance the field meaningfully, according to scientists.
Berkeley
Lab's inertial
fusion energy research has emphasized ion beams — focused by
magnetic fields, not materials like glass, and accelerated by induction accelerators.
There are two approaches to
fusion energy, inertial confinement (the National Ignition Facility or NIF at Lawrence Livermore National
Lab, for example) and
magnetic confinement (the International Thermonuclear Experimental Reactor or ITER, for example).
