采用示踪剂封装固体颗粒（TESPEL）诊断颗粒输运。TESPEL由聚苯乙烯为外壳，另一种材料为内芯组成。首先，在致密螺旋系统（CHS）上证实了锂的示踪剂在等离子体中有局部沉积。此外，用电荷交换复合光谱观察了示踪粒子的行为。TESPEL也被注射到大螺旋装置（LHD）中。在这种情况下，不需要中性光束就可以观察到钛的Kα线，表明这种方法是有前途的。
A method using a tracer-encapsulated solid pellet (TESPEL) has been developed to diagnose particle transport. TESPEL consists of polystyrene as the outer part and another material as the inner core. At first, it was confirmed at the compact helical system (CHS) that the tracer of lithium was deposited locally in the plasma. Moreover, the behaviour of the tracer particles was observed by charge exchange recombination spectroscopy. TESPEL was also injected into the large helical device (LHD). In this case, the Kα line of titanium was observed without the necessity of a neutral beam, and it was shown that this method is promising.
