Abstract
Čestice fuzijske prašine iz tokamaka JET analizirane su snopom iona helija-3 energije 4 MeVa. Kako bi se našli tragovi fuzijskog goriva korištene su analitičke metode NRA i PIXE. Poseban naglasak je stavljen na geometriju eksperimenta zbog velikog prostornog kuta NRA detektora. Analiza je pokazala da su čestice fuzijske prašine sačinjene od volframa, inkonela (nikla, željeza, kroma, niobija, molibdena), deuterija, berilija, dušika itd. Većina čestica je podrijetlom iz dijelova reaktorske komore koji su izloženi plazmi, no dio ih je nefuzijskog podrijetla. Potonje su vjerojatno nastale kontaminacijom tokom održavanja.
Abstract (english)
Fusion dust particles from the JET tokamak were analyzed using a 4 MeV helium-3 microbeam. NRA and PIXE methods were used with the aim of finding residual fusion fuel (deuterium) in fusion dust particles. Particular emphasis has been put on the geometry of the experiment due to the large solid angle of the surface barrier detector used in the analysis. The analysis has shown that the particles are comprised of tungsten, inconel (nickel, iron, chromium, niobium, molibdenum), deuterium, beryllium, nitrogen, etc. While the most of the particles are a result of plasma interacting with plasma-facing components, some of them are clearly non-fusion in origin. The latter particles are most probably the result of maintenance procedures.
