Heating and current drive on NSTX
Low aspect ratio tokamaks pose interesting new challenges for heating and current drive. The NSTX (National Spherical Tokamak Experiment) device to be built at Princeton is a low aspect ratio toroidal...

Applications of fast wave in spherical tokamaks
In spherical tokamaks (ST), the magnetic field strength varies over a wide range across the plasma, and at high betas it deviates significantly from the 1/R dependence of conventional tokamaks. This, ...

Radio Frequency auxiliary heating for Low Aspect Ratio Tokamaks can facilitate startup and access to high energy density plasmas, reduce the demand on ohmic core volt-seconds, and provide off axis electron heating for a high 
e plasma. Calculations for several waves both below and at high harmonics of the ion cyclotron frequency predict significant RF heating even at the lower electron temperatures and densities typical of startup plasmas. Real time adjustments of the antenna array phasing can track plasma start up evolution. ©1997 American Institute of Physics.
