“…For the whole set of chosen equation you can refer to. [22][23][24][25][26][27][28][29][30] In order to break the symmetry of the background plasma and excite the filamentary patterns, high density column of electron and ion is introduced to the center of the plasma. It is noted that the time required for the evolution of filamentary patterns is shorter if a larger perturbation is introduced into the plasma bulk so we assumed the perturbation column to have a density of 5 × 10 15 m −3 (i.e.…”

Growth of nanoparticles in plasmas is an emerging topic of research due to its numerous implications in industrial, and fusion plasmas applications. In this paper, effect of a magnetic field induced filaments on the growing nanoparticles and vice versa has been investigated. The experiment has been performed in a capacitive coupled radio-frequency Ar/C2H2 discharge. The magnetic field affect the plasma dynamics and confined it within the electrodes. At a very high magnetic field (B ≥ 1 T) a stationary or moving filamentary structures are formed between the electrodes that are aligned along the magnetic field. These filamentary structures are found to be suppressed during nanoparticle growth. A particle in cell simulation has been performed to understand the suppression of these filamentary structure.

“…The research interest in such discharge obviously is not weakened [15], [16], [17], [18], [19], [20], [21]. Yuan et al simulated an electron beam generated by a glow discharge with grid anode [4], [22] and found that a DC glow discharge with grid anode could be used as part of a larger coating mounted on an aircraft to provide a plasma envelope that could be turned on and off.…”

The characteristics of post-cathode plasma maintained by a self-made DC short glow-discharge plasma generator with grid electrodes were measured by optical emission spectroscopy. The discharge existed in an abnormal glow discharge mode at a voltage of 250-400 V and a helium pressure of 3-15 Torr and a discharge gap of 3 mm. The results indicate that the intensity distribution of helium atom spectral lines in the post-cathode space differs from that in the post-anode space. The temperature of electron excitation in the post-cathode plasma reaches its peak of 1500-3000K at 5-6 mm from the grid cathode. The difference in the intensity distributions of helium atom spectral lines in the post-cathode and post-anode spaces is associated with electron generation mechanism in these cases.INDEX TERMS Glow discharge, grid anode, spectral characteristics, post-anode plasma, effective thickness of plasma.

This paper presents a new composite grid electrode structure for the generation of plasma that is suitable for modeling microwave radiation transmission through atmospheric plasma. The new grid anode-composite cathode (GA-CC) structure is to be contrasted with the ordinary grid anode-cathode plate (GA-CP) structure. It is found that the breakdown voltage of the new GA-CC electrode structure is lower than that of the GA-CP structure and is a bit shifted to the right on the Pd-axis. An advantage of the GA-CC structure over the GA-CP structure is that it requires a lower voltage to generate the same current. It is found that plasma generated by the new GA-CC structure selectively strengthens electromagnetic waves attenuation in the frequency range of 9-12 GHz.
