摘要：

The evidences for the structures of similar topology (a tubule with a cartwheel in the edge cross-section) and very different length scale are found in the tokamak dust and tokamak plasmas. In the dust deposit, such structures of 50-100 nm diameter are assembled from tubules of the size typical for multiwall carbon nanotubes. In the plasma, similar structures of centimeter scale diameter are observed in the visible Light emission. These data are compatible with the hypothesis about microsolid skeletons, assembled from carbon nanotubes (or similar nanostructures), of the observed long-living filaments in plasmas.
