Tokamak start-up with electron-cyclotron heating. Holly, D., J., Prager, S., C., Shepard, D., A., & Sprott, J., C. Nuclear Fusion, 21(11):1483, 1981.
Paper
Website abstract bibtex Experiments are described in which the start-up voltage in a tokamak
is reduced by about a factor of two by the use of a modest amount
of electron cyclotron resonance heating power for pre-ionization.
The solution of the zero-dimensional start-up equations indicates
that the effect is due to the high initial density which increases
the rate at which the conductivity increases in the neutral-dominated
initial plasma. The effect extrapolates favourably to larger tokamaks.
A 50% reduction in the start-up volt-second requirement and impurity
reflux is also observed.
