Measurements of the Beam-Driven Current in the DITE Tokamak

Abstract

The beam-driven current produced by neutral injection into the DITE tokamak has been measured. The variation of this current with electron density and gas current has also been investigated. Good agreement is found between experiment and a model in which the Fokker-Planck equation describes the fast-ion distribution and a magnetic field diffusion equation gives the time dependence of the electromagnetic fields.
