Azimuthal electric fields and ambipolarity in a multiple-helicity torsatron

D. E. Hastings, K. C. Shaing

Research output: Contribution to journalArticlepeer-review


In a torsatron there are multiple solutions to the ambipolarity relationship for the electric field. If the electric field is small over some region of space then the self-consistent poloidal electric field can be important and lead to potential islands. If the plasma is in the superbanana plateau regime, then slow resonant particles limit the rate of change of the electric field and, hence, give a minimum width for the spatial zone where the plasma is changing roots of the ambipolarity relationship.
