Fast ion source and detector for investigating the interaction of turbulence with suprathermal ions in a low temperature toroidal plasma
Abstract
A specific experimental apparatus consisting of an ion source and a detector for the investigation of the interaction between suprathermal ions and drift-wave turbulence is developed on the toroidal plasma experiment. Due to the low plasma temperature (∼5 eV), a spatially localized, small-size ion source (∼4 cm) mounted inside the vacuum vessel with relatively low ion energy (∼100 eV-1 keV) can be used. The source consists of an aluminosilicate Li-6 ion emitter (6 mm diameter, 10-30 μA current) installed on a two-dimensional (2D) poloidally moving system. The location, energy, and current density profile of the ion beam will be measured using a 2D movable gridded energy analyzer. © 2006 American Institute of Physics.
