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…
