SUMMARY:Smaller and Sooner: Exploiting new superconductor technology t
 o accelerate fusion's development \, Plasma Physics (Physics/ECE/NE 92
 2) Seminar\, Dennis Whyte\, MIT
DESCRIPTION:Rare-Earth Barium Copper oxide (REBCO) superconductor (SC)
  tapes are a newly available technology that promise to revolutionize 
 plasma and fusion research. REBCO are superconducting at liquid nitrog
 en temperature\, providing easy access to ~1-2 tesla steady-state magn
 etic fields in the laboratory and\, unlike standard SCs\, have almost 
 no degradation of their critical current at high magnetic fields when 
 sub-cooled. These features allow >23 tesla magnetic coils\, double the
  B-field of standard SC such as used in ITER\, and the design of demou
 ntable SC coils. The implications of such coils have been examined in 
 ARC\, a conceptual tokamak fusion pilot plant. Exploiting the B4 depen
 dence in fusion power density\, ARC produces >500 MW in a device 1/8th
  the volume of ITER. Demountable coils permit modular internal compone
 nts and a simple liquid immersion blanket. The compact\, high-B tokama
 k provides for robust steady-state operational regimes with largely de
 monstrated physics\, while high-B provides the margin to transient and
  disruption limits needed in burning plasmas. Critical path science an
 d technology R&D issues are discussed that would enable this attractiv
 e path to smaller\, more flexible fusion devices.
