The sheath formation mechanism is modeled in a four-component collisional
electronegative warm plasma considering the behavior of positive ions by fluid equations …

Potential double layers are observed to form as nested cylindrical sheaths that energize
charge particles in the absence of any externally applied magnetic field. These visibly …

Low-frequency sheath oscillations, initiated by the sheath-plasma instability, are observed in
connection with the complex structure formations in expanding radio frequency (RF) plasma …

Intensely luminous double layers develop and then expand in size in a visibly glowing RF
discharge produced using a plasma source consisting of a semi-transparent cylindrical …

Parametric characterization of multiple double layers is done during high pressure glow
discharge in a toroidal vessel of small aspect ratio. Although glow discharge (without …

Experimental investigations of a hollow cathode discharge through the controlled variation
of anode potential inside a hollow cylindrical cavity, in the absence and presence of the …

A hollow cathode source is designed to generate multiple double layer (MDL) structures by
the trapping of charged particles in the absence of any auxiliary plasma source or magnetic …

Multiple luminous sheath structures develop in the localised plasma formation inside a
cylindrical gridded cathode plasma source. These structures gradually expand into the …

Helicity in the dynamo field components of helicon wave is examined during the novel study
of wave induced helicity current drive. Strong poloidal asymmetry in the wave magnetic field …

Wave magnetic field components are measured across the radius (− 10 cm≤ r≤ 10 cm) for
a low-pressure (0.3 mbar) helicon discharge, in a toroidal vacuum chamber of small aspect …
