Skeletal dendritic structure of dust microparticles and of their agglomerates in tokamak T-10

Electrodynamic Aggregation of Nanodust as a Source of Long-Lived Filaments in Laboratory Electric Discharges and Space

“…1) the presence of skeletal structures of certain distinctive topology (namely, tubular and cartwheellike structures, and their simple combinations) in the range of 10 −5 -10 23 cm in laboratory electric discharges of various type [13] (including the dust deposits in tokamak [14], [15]), severe weather phenomena [16]- [18], and space [17]; 2) the trend toward self-similarity within above skeletal structures; 3) self-illumination of skeletal structures, in their critical points, in the range of 10 −1 -10 22 cm (e.g., the shining butt-end of a truncated filament) [17], [19]; 4) some signs of skeletal structuring in the galaxy redshift surveys in the range of 10 24 -10 26 cm [16], [20]. The proof-of-concept studies enabled us to call these structures (namely, tubular and cartwheellike structures, and their simple combinations) a USS [21].…”

“…The topological identity (i.e., the similarity) of the above structures (particularly, of the cartwheel as a structure of essentially nonhydrodynamic nature) and the observed trend toward assembling of bigger structures from similar smaller ones (i.e., the self-similarity), which are identified in the range of 10 −5 -10 23 cm, enabled us to put all these skeletal structures under one roof and claim the probable presence, in these structures, of a skeleton composed of a fractal condensed matter of particular topology of the fractal [17]. Specifically, this matter may be self-assembled from nanotubular blocks in a way predicted in [1], [2], and [9] (formation of tubular macroblocks from tubular nanoblocks) and found in the skeletons in the submicrometer dust particles [14], [15]. Also, the following facts, namely:…”

Self-assembling of tubular skeletons from electric current filaments composed of magnetized thin rods

“…Here we report on numerical modeling, in the framework of the approach [2], of dynamics of ∼ 10 2 -10 3 nanodipoles and make a qualitative comparison with the analysis [15,16] of the data on transmission electron microscopy of submicron particles in the dust deposits in tokamak, and with experiments on laser production of large carbon-based toroids [17], including the Q-shaped toroids.…”

Temperature and spectroscopic characteristics of homogeneous co-deposited carbon–deuterium films produced in the T-10 tokamak

“…The translucent homogeneous reddish-gold films, or 'flakes' of 10-30 µm thickness have a complicated internal nanostructure [4][5][6][7] and a [D]/[C] atomic ratio of up to 0.8 [1]. Unless regularly removed, these films may accumulate much tritium, thus posing a severe problem for the safety of the International Thermonuclear Experimental Reactor (ITER).…”
