The Tracer-Encapsulated Solid PELlet (TESPEL) injection is one of the simplest new ideas to study the impurity confinement and other plasma properties. The special features of this method are: (a) local deposition inside the plasma, (b) precise knowledge of the deposited tracer amount, (c) wide selection of tracer materials. The achievements of the multi-functional diagnostics using TESPEL injection on LHD are to measure: (a) impurity transport properties, (b) heat diffusivity, (c) particle flow features in and out of the magnetic island, and (d) fast neutral particle fluxes.
