Monbusho; Ministry o£ Education, Science and Culture, Japan, after 

 its Japanese acronym. 



Neutral-beam injection: Heating of contained plasma toward 



ignition by injection of beams of energetic (typically greater than 

 100 thousand electronvolt) neutral atoms, which can cross the 

 magnetic lines of force but which are later ionized in the 

 contained plasma, thus being themselves contained. 



NET: Next European Torus. 



ORNL: Oak Ridge National Laboratory. 



OTR: A next-generation engineering test reactor, USSR. 



Plasma: A gas comprising some large fraction of charged particles. 



Radio-frequency heating: The application of radio- frequency 



eletromagnetic power (loosely speaking — microwave power is included 

 under this rubric) , which, when in resonance with the gyromagnetic 

 properties of the plasma, can be used to deposit energy in it, thus 

 heating toward ignition. 



Reversed- field pinch: An alternative magnetic confinement concept 

 under investigation in several countries. 



RTNS-II: Rotating Target Neutron Source II. 



STA: Science and Technology Agency, Japan. 



Stellarator: A toroidal device (pioneered in the United States) 



wherein plasma equilibrium and stability are achieved by externally 

 imposed magnetic fields rather than by torodial currents within the 

 plasma, as in the tokamak. 



Super-Phenix: A 1200-megawatt (electric) fast breeder reactor, in 

 France. 



Tandem mirror: A magnetic containment device in which two mirror 

 machines close the ends of a simple magnetic solenoid. 



TEXTOR: A plasma technology experiment built by the Federal Rebublic 

 of Germany. 



TFCX: Tokamak Fusion Core Experiment, proposed in the United States. 



TFTR: Tokamak Fusion Test Ractor, Plasma Physics Laboratory, 

 Princeton University. 



TORE SUPRA: Tokamak being built at Caderache, France. 



Tokamak: A magnetic containment device in which the magnetic lines 

 of force are closed on themselves in the shape of a torus, with a 

 large current flowing through the plasma. 



Toroidal: The azimuthal direction, about the central axis, within 

 a toroidal containment device. 



U.K.: United Kingdom.
