Enhanced Target Interaction Area of Helical Plasma Plumes in a Pulsed RF Atmospheric Plasma Jet
Radhika T P, Satyananda Kar
Helical plasma plumes generated in pulsed radiofrequency atmospheric pressure plasma jets exhibit unique flow dynamics arising from the coupling between Kelvin-Helmholtz instabilit…
Development and optimization of low power non-thermal plasma jet operational parameters for treating dyes and emerging contaminants
Deepchandra Joshi, G. Veda Prakash Shaikh Ziauddin Ahammad, Satyananda Kar +1
Emerging contaminants (ECs) have come out as the latest class of environmental contaminants, which are highly recalcitrant and toxic in nature. Currently, no suitable rectification…
Influence of pulse modulation frequency on helium RF atmospheric pressure plasma jet characteristics
Mahreen, G. Veda Prakash, Satyananda Kar +2
This work investigates the influence of pulse modulation frequency ranging from 50 Hz- 10 kHz on the helium RF atmospheric pressure plasma jet's fundamental characteristics. The im…
Excitation of helical shape argon atmospheric pressure plasma jet using RF pulse modulation
Mahreen Khan, Veda Prakash G., Satyananda Kar +2
The article reports the excitation of a helical argon atmospheric pressure plasma jet using a pulse modulated 13.56 MHz radiofrequency (RF) power source. This helical structure is…
A Joint Calibration Technique for Improving Measurement Accuracy of Voltage and Current Probes During Synchronous Operation for RF Based Plasma Devices
Mahreen, A. Ganguli, Veda Prakash Gajula +2
This paper presents a joint calibration scheme for voltage (V) and current (I) probes that helps resolve accurately voltage-current phase differences even when the difference is ve…
Observations of Pressure Anisotropy Effects within Semi-Collisional Magnetized-Plasma Bubbles
E. R. Tubman, A. S. Joglekar, A. F. A. Bott +21

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…
Microwave power coupling in a surface wave excited plasma
Satyananda Kar, Lukas Alberts, Hiroyuki Kousaka
In recent decades, different types of plasma sources have been used for various types of plasma processing, such as, etching and thin film deposition. The critical parameter for ef…
Generation of a neutral, high-density electron-positron plasma in the laboratory
G. Sarri, K. Poder, J. Cole +17
We report on the laser-driven generation of purely neutral, relativistic electron-positron pair plasmas. The overall charge neutrality, high average Lorentz factor ($γ_{e/p} \appro…
