摘要：
In order to investigate fluctuations in the edge regions of tokamaks and their influence on particle and energy transport, we are developing an ñ diagnostic for the DIII-D system based on an injected neutral lithium beam. Analysis of the 670.8 nm light emitted along the beam trajectory due to collisional excitation should yield the behavior of the electron density and its associated fluctuations in the edge region of DIII-D in both L- and H-mode plasma configurations. The planned system, design considerations, and expected performance levels will be presented.
