Summary: Fusion energy represents a promising alternative to 
         fossil fuels and nuclear fission for world energy 
         production. This Glossary is a compendium of Frequently Used
         Terms in Plasma Physics and Fusion Energy Research.  Refer
         to the FAQ on Conventional Fusion for more detailed info
         about topics in fusion research.  This Glossary does NOT 
         discuss unconventional forms of fusion (like Cold Fusion).

# J:  variable used to indicate current density

$ J:  abbreviation for Joule; see entry

@ JET:  Joint European Torus; see entry

@ JT-60, JT-60U: Japan Torus - 60 (Upgrade); see entry

> Janus:  Early Inertial Confinement laser system at 
Livermore; used for one- and two-beam laser-target 
irradiation experiments in 1974 and 1975.

> Joint European Torus:  Large tokamak next to the Culham 
Laboratory in Oxfordshire, England, commonly owned by the 
European Community.  First reactor to achieve > 1 MW of fusion 
power, in 1991.  Largest tokamak currently in operation (to the 
best of the editor's knowledge).

> JT-60: A large Japanese tokamak, located north of Tokyo.
JT-60U is an "upgrade" to JT-60 now in operation.

$ Joule:  SI unit of energy.  1 Joule = 1E7 ergs = 1 Watt of
power occurring for one second.  1 Joule is roughly 0.001 BTU
and 1 calorie is roughly 4 joules.  There are 3.6 million joules
in a kilowatt hour.
