Title:

Thermal and Electric Oscillation Driven by Orbit Loss in Helical Systems

Date of publication:

Mar. 1993

Key words:

radial electric field, direct orbit loss, oscillation, energy confinement time, slowing down time, torsatron/heliotron

Abstract:

Coupled oscillation of the radial electric field, the heating power and the plasma temperature in helical systems is analysed. This oscillation is caused by the influence of the radial electric field on the direct loss of injected fast ions. The damped oscillations of the radial electric filed, temperature and fast-ion loss are predicted. Conditions for the mode and the dependence of the frequency are discussed.
