Plasma Blob and Temperature (IMAGE)
Caption
(a) Temporal changes in the 3-D spatial distribution of a plasma blob (time passes from right to left) are shown. A plasma blob (Plasma Filament) is expressed with the permeated tube in green, and at the four cross-sections in different places the high-density region is shown in red and the low-density region is shown in green. Together with the passage of time the plasma blob is moving (to the left) toward the vessel wall. (b) The velocity distribution of plasma particles (electrons) [vocabulary 3]. The width of the velocity distribution represents the temperature. By understanding the micro internal structure such as a velocity distribution, it becomes possible to investigate the influence that the structure gives to the plasma blob's movement.
