摘要：

Dust has been collected and analyzed from NSTX at PPPL and JT-60U at JAERI-Naka. A total quantity of 39 mg of dust was collected from NSTX, and 170 mg was obtained from sampling areas in JT-60U. Particle sizes determined by count-based measurements from all locations in NSTX averaged 3.27 mu m, and JT-60U dust has a similar average size of 3.08 mu m. Dust from both devices was composed mainly of carbon. Specific surface areas of two dust samples from JT-60U are 1.18 m(2)/g and 0.28 m(2)/g. NSTX samples contained insufficient mass for measuring specific surface area. Details from the analysis of each dust collection activity in NSTX and JT-60U are described in this paper.
