Outline of Final Research Achievements

To measure the size, density, charge and flux of nanoparticle, we have developed a novel nanoparticle detection method using a compact drift tube. In this study, we have fabricate a dc-bias type compact drift tube and measured dynamics of nanoparticles by sampling them at the side wall of the tube.
We have obtaied following conclusions: (1) Sampled particles are melted in plasmas, and (2) The information of nanoparticle transport in tube can be obtained from position dependence of size distribution and incident angle of sampled particles. The characteristics of nanoparticles should be involved in these results.
