New Formalism for Modelling Flowing Plasmas in a Magnetic Field
Subhasish Bag, Ashish Ganguli, Vikrant Saxena +2
A new formalism for modelling a flowing plasma in a magnetic field, having potential for application in plasma thrusters, materials processing, space plasmas, etc., is developed. I…
Mass Spectrometry Studies of Hydrogen Ions Energy Distributions in an ECR- based Large Volume Plasma Source
Bibekananda Naik, Ramesh Narayanan, Debaprasad Sahu +2
Plasma is produced in a Large Volume Plasma Source (LVPS; dia. = 1 m, height = 1m) using CW microwaves (= 400 - 600 W, 2.45 GHz), in a compact ECR plasma source (CEPS) attached to…
Experimental and Theoretical Study of Flow Dynamics of Expanding Hydrogen Plasma from an ECR Plasma Source
Priti Singh, Ramesh Narayanan, Ashish Ganguli +2
The flow of moderately dense (n {\approx} 10^{11} cm^{-3}) hydrogen plasma with high electron temperature (T_{e} {\approx} 30 - 35 eV) and plasma potential (V_{p} {\approx} 100 V),…
Investigation of high pressure capacitively coupled plasmas produced by electrons energized in DC sheath at powered electrode
Anuravi Sharma, Ramesh Narayanan, Arti Rawat +1
A 13.56 MHz, capacitively coupled plasma is investigated experimentally to determine the power absorption mechanism across a wide pressure range ({\approx} 5 - 600 mTorr) at {\appr…
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…
