Cryogenics for large scale applications

The discovery of high-temperature superconductors in 1986 seemed to herald the end of the era of large cryogenic systems. Phase transition temperatures of up to 138 K were achieved in ceramic materials within a short period of time. Superconductivity at room temperature seemed within reach. However, further success proved much more difficult than expected. The material class of hydrides, for...

Oral

Princeton Plasma Physics Laboratory (PPPL) is a DOE national laboratory focused on plasma physics and nuclear fusion science. Our primary mission is research into and development of fusion as an energy source. PPPL recently developed a REBCO coated conductor continuous in-field characterization system and tested a large warm bore conduction cooled Nb3Sn model coil capable of generating 6 T in...

86. On the use of a hyperconducting centre solenoid for spherical tokamaks

Cryogenics for large scale applications

Oral or Poster

Tokamaks rely upon a centre solenoid to initiate and warm up the plasma at the beginning of each pulse [1]. A conventional centre solenoid consisting of hollow copper conductors and insulated with epoxy resin-impregnated glass and kapton tape was used in JET [2]. In the larger ITER, however, it was decided that only a superconducting coil could fulfil the flux requirements. NbTi cooled down to...
