Description

In order to study impurity particle transport by a transient response of the tracer ions, Tracer-Encapsulated Solid PELlet (TESPEL) has been developed. TESPEL consists of polystyrene (-CH(C6H5)CH2-)n as an outer shell and tracer particles as an inner core. In case of the titanium (Ti) tracer, the temporal behavior of line emissions from the highly ionized tracer ions has been clearly observed by both X-ray pulse height analyzer (PHA) and a vacuum ultra violet (VUV) spectrometer. These experimental obtained data are compared with the ones simulated by the impurity transport code, MIST. Moreover, the propagation of the cold pulse caused by TESPEL injection was observed by a 32-channel electron cyclotron emission (ECE) heterodyne radiometer and the heat plasma conductivity has been evaluated.
