TESPEL consists of polystyrene as an outer part and LiH as an inner core. For proving the essential concept of the new diagnostics, TESPEL is injected into a neutral-beam-heated plasma of the Compact Helical System. This experiment shows the successful local deposition of the tracer, and the behavior of tracer particles deposited locally in the plasma core region is also observed by a method of charge exchange recombination spectroscopy. Thus, our new diagnostic concept has been proven for the first time from the viewpoints of both the production method of a tracer-encapsulated pellet as well as from the observation of the tracer particles.}, title = {Particle Transport Study with Tracer-Encapsulated Solid Pellet Injection}, year = {1998} }
