Abstract
A tracer-encapsulated solid pellet (TESPEL) injection system for the TJ-II stellarator was recently
developed. In order to reduce the time and cost for the development, we combined a TESPEL injector
provided by National Institute for Fusion Science with an existing TJ-II cryogenic pellet injection
system. Consequently, the TESPEL injection into the TJ-II plasma was successfully achieved,
which was confirmed by several pellet diagnostics including a normal-incidence spectrometer for
monitoring a tracer impurity behavior.
