摘要：
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 (similar to 5 eV), a spatially localized, small-size ion source (similar to 4 cm) mounted inside the vacuum vessel with relatively low ion energy (similar to 100 eV-1 keV) can be used. The source consists of an aluminosilicate Li-6 ion emitter (6 mm diameter, 10-30 mu A 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. (c) 2006 American Institute of Physics.
