Development of Volume Produced Negative Ion Source using a CCRF Discharge
Pawandeep Singh, Swati Dahiya, Avnish Pandey +2
This work shows the development of a volume-produced negative ion source that consists of annular parallel plates driven by a 13.56 MHz capacitively coupled radio frequency in a pu…

Sheath effects with thermal electrons on the resonance frequency of a DC-biased hairpin probe
Pawandeep Singh, Avnish Pandey, Swati Dahiya +3
The dielectric constant of a sheath, whether ionic or electronic, formed around the cylindrical limbs of a hairpin probe, is often considered the same as that of a vacuum. However,…

Experimental investigation of an electronegative cylindrical capacitively coupled geometrically asymmetric plasma discharge with an axisymmetric magnetic field
Swati Dahiya, Narayan Sharma, Shivani Geete +3
In this study, we have investigated the production of negative ions by mixing electronegative oxygen gas with electropositive argon gas in a geometrically asymmetric cylindrical ca…
