Abstract

The authors have designed and are conducting a current profile control experiment aimed at reducing fluctuations and improving confinement in RFP plasmas. Profile modification is achieved via electrostatic injection of electrons from approx.30 miniature plasma sources. Each source produces a 1 kA electron beam which is dense (approx 150 kA/cm2 at 70 cm from the source), highly directional, and without large impurity content. An initial multi-injector experiment in which a total current of 5 kA was injected is completed.
