Perspective: The dusty plasma experiments a learning tool for physics graduate students
Mangilal Choudhary
The plasma is an ionized gas that responses collectively to any external (or internal) perturbations. Introducing micron-sized solid dust grains into plasma makes it more interesti…
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…
