Heating & Current Drive Systems

RF-EBW

RF heating synergistically enhance LHI/CHI efficiency

  • Classical helicity dissipation scaling :  Rp ~ Te-3/2

EBW can couple to over-dense ST plasmas

Collaboration with ORNL

  • 8Ghz, ~ 500 kW system previously used on FT

Possible expansion to add ECH and ECCD
