Experimental observation of pinned solitons in a flowing dusty plasma
Garima Arora, P Bandyopadhyay, M G Hariprasad +1
Pinned solitons are a special class of nonlinear solutions created by a supersonically moving object in a fluid. They move with the same velocity as the moving object and thereby r…
An enhanced operating regime for high frequency capacitive discharges
Sanket Patil, Sarveshwar Sharma, Sudip Sengupta +2
We report the existence of an enhanced operating regime for a high-frequency, low-pressure capacitively coupled plasma (CCP) discharge in the presence of a weak magnetic field appl…
Excitation of dust acoustic shock waves in an inhomogeneous dusty plasma
Garima Arora, P. Bandyopadhyay, M. G. Hariprasad +1
An experimental investigation of the propagation characteristics of shock waves in an inhomogeneous dusty plasma is carried out in the Dusty Plasma Experimental (DPEx) device. A ho…
Driving frequency effect on discharge parameters and higher harmonic generation in capacitive discharges at constant power densities
Sarveshwar Sharma, Nishant Sirse, Animesh Kuley +2
Very high frequency (VHF) driven capacitive discharges are now being increasingly adopted for plasma-based materials processing due to their high processing rates and lower substra…
Experimental observation of a first order phase transition in a complex plasma mono-layer crystal
M. G. Hariprasad, P. Bandyopadhyay, Garima Arora +1
The formation and melting of a mono-layered charged dust particle crystal in a DC glow discharge Argon plasma is studied. The nature of the melting/formation process is established…
