How to track impurities such as titanium, iron, nickel, copper or tungsten migrating throughout fusion plasmas? It is possible that tiny hand-made pellets manage to perform this task. The study is carried out by three fusion parties, namely NIFS in Japan, CIEMAT in Spain and Max Planck Institute for Plasma Physics (IPP) in Germany.
According to fusion researcher René Bussiahn from IPP Greifswald, the Tracer Encapsulated Solid Pellets (TESPELs) proved very reliable in depositing impurities in the core plasma and observing their behaviour. Impurity transport study is one of the main task perform in many fusion devices. The upcoming W7-X campaign will involve 100 to 200 TESPELs fabricated in CIEMAT dedicated laboratory.
