Rotational properties of annulus dusty plasma in a strong magnetic field
Mangilal Choudhary, Roman Bergert, Sandra Moritz +2
The collective dynamics of annulus dusty plasma formed between a co-centric conducting (non-conducting) disk and ring configuration is studied in a strongly magnetized radio-freque…
3-Dimensional Dusty Plasma in a Strong Magnetic Field: Observation of Rotating Dust Tori
Mangilal Choudhary, Roman Bergert, Slobodan Mitic +1
The paper reports on the dynamics of a 3-dimensional dusty plasma in a strong magnetic field. An electrostatic potential well created by a conducting or non-conducting ring in the…
Influence of External Magnetic Field on DustAcoustic Waves in a Capacitive RF Discharge
Mangilal Choudhary, Roman Bergert, Slobodan Mitic +1
This paper reports experiments on selfexcited dust acoustic waves (DAWs) and its propagation characteristics in a magnetized rf discharge plasma. The DAWs are spontaneously exci…
Comparative Study of the Surface Potential of Magnetic and Non-magnetic Spherical Objects in a Magnetized RF Discharge Plasma
Mangilal Choudhary, Roman Berger, Slobodan Mitic +1
We report measurements of the time-averaged surface floating potential of magnetic and non-magnetic spherical probes (or large dust particles) immersed in a magnetized capacitively…
Transport and trapping of dust particles in a potential well created by inductively coupled diffused plasma
Mangilal Choudhary, S. Mukherjee, P. Bandyopadhyay
A versatile linear dusty (complex) plasma device is designed to study the transport and dynamical behavior of dust particles in a large volume. Diffused inductively coupled plasma…
Transient evolution of solitary electron holes in low pressure laboratory plasma
Mangilal Choudhary, Satyananda Kar, Subroto Mukherjee
Solitary electrons holes (SEHs) are localized electrostatic positive potential structures in collisionless plasmas. These are vortex-like structures in the electron phase space. It…
