Call for Papers

Background:

Since the gaseous discharging plasma is complex, it is systematically studied by means of the methods of numerical simulation, experimental diagnostic, and analytical theory. With respect to the numerical calculation, we can develop the simulation code, such as fluid model and particle model by ourselves, through the fortran or C++ computer language, or rely directly on the commercial softwares, such as Analysis, Comsol, Pegsus, or Quantemol, etc. Whether using the self-written code or the commercial software, the discharge profiles are always the preliminary data that people are confronted with. At interpreting these profiles of different parameters of plasma, such as density, temperature, charge density, potential, electromagnetic field, flux of mass and energy, and velocity of species etc., the concept of discharge structure is constructed. Usually, the discharge structure of electropositive discharging plasma such as the argon inductively coupled plasma (ICP) is characterized by the parabola and Bessel functions, respectively in axial and radial directions, at the assumption of azimuthal symmetry. While the discharge structure of electropositive plasma is understandable and moreover it is validated by means of simulation, theory and experiment, the discharge structure of electronegative plasma is quite unknown and less cared about yet. Regarding the fact that the industrial plasmas are almost the electronegative plasma type, a systematic study of discharge structure of such plasmas is important since it helps people better recognize the plasma source and hence optimize present plasma techniques and excite new frontier of application in future, probably.

Goal/Rationale:

Actually, the structure of electronegative plasma has been investigated since the 80s of last century, but most of the studies are focused on the analytical theory of fluid model at that time. The theory utilized many assumptions, such as the constant temperature profile, collisionless, cold ions, and net positive chemical source for species, etc. At these approximations, the ambi-polar diffusion of electronegative plasma, the stratification of discharge, the double layer dynamics, and the parabola, ellipse, and flat-top ionic density profiles were given. Presently, the self-consistent fluid simulation technique with less approximations is fully developed, and the plasma model of fluid simulation of Comsol related to the Ar/SF6 ICP generates perfectly the above discharge structure. Moreover, since it is a self-consistent simulation, it is found that the self-coagulation dynamics that consists of free diffusion and net negative chemical source and is centered in the structure prevails, and together with the above other structures, the discharge of electronegative plasma is hierarchical. Furthermore, the correlations of the self-coagulation with the assistance of compressible heating and the discharge hierarchy, to the wave-particle duality of quantum, the nuclear fusion of astrophysical plasma, the particle physics with respect to the Yukawa’s potential, and the geophysical structure morphology are displayed. It is believed that the plasma state experiences the cold plasma (i.e., glow discharge), the thermal plasma (i.e., arc discharge), and the fusion plasma (i.e., nuclear reaction), by means of the self-coagulation and compressible heating. Besides, the self-coagulation is found universal, existing in the chemical dynamics of ions, electrons, and neutrals, and even in the thermal energy dynamics, i.e., not mass transport, but energy transport.

Scope and Information for Participants:

The last conference of this topic preliminarily built the connection between the different branches of plasma physics, since we already included presentations given in the fields of low and high temperature plasmas. As we know, it is the first time for the two plasma sources formally interacting in an academic conference, since they are usually separately reported before. In this new workshop, we address the physical reason why the two types of plasma sources are connected, and moreover the workshop is aimed at widening the inter-disciplinary works from the plasma field itself to the connection of plasma to other fields, such as quantum, particle, nucleus, astrophysics and geophysics.
