"Big Science" Descriptor ; Magnetic fusion 



Description of Facility/Instrument : JFT-2M Is a medium-sized tokamak. 

 It serves as a test bed for the radio frequency (RF) heating and 

 current drive that Is to be used In JT-60. It Is similar in size 

 and research program to PLT in the United States.

"Big Science" Descriptor ; Magnetic fusion 



Description of Facility/Instrument ; GAMMA 10 is the Japanese thermal 

 barrier tandem mirror experiment. Its parameters are comparable 

 to TMX-U in the U.S. program. GAMMA 10 is different from TMX-U 

 in that its end plugs have more axlsymmetry, which Is expected to 

 Increase radical confinement. On the other hand, the end plugs 

 are larger than the TMX-U end plugs, and this is a disadvantage.

In designing GAMMA 10, the Japanese collaborated with 

 scientists from the U.S. mirror program because of their 

 experience in designing TARA and TMX-U.
