There are a number of pressing problems mankind is facing today that could, at least in part,
be resolved by space systems. These include capabilities for fast and far-reaching …

Comprehensive collisional radiative (CR) models have been developed for the diagnostic of
argon plasma using Ar and Ar+ emission lines. The present CR models consist of 42 and …

Neutral beam injection (NBI) is known as one of the important methods of plasma auxiliary
heating and current drive in fusion reactors. Optimization of the ion sources, as one of the …

The Helicon Plasma Source (HeliPS) designed and developed at the Centre of Plasma
Physics—Institute for Plasma Research is a versatile helicon plasma device, which operates …

Multiple potential drops have been observed in the presence of a thick grounded ring when
Argon plasma is allowed to expand in a Helicon Plasma Source (HeliPS) setup. Potential …

Oxygen (O 2) helicon plasmas in multiple wave modes were excited by a right-helical
antenna with an upper metal endplate at low pressure. Mode transitions were observed at …

In recent years, helicon plasma sources have attracted much attention from scientific centers
and industry. In this regard, the power coupling is of particular importance for the production …

This paper reports the study of the effects of an externally applied magnetic field (0–300 G),
in the mode transition as well as in the radial and axial variation of different plasma …

Negative ion rich oxygen plasma at low pressure is produced in a Helicon Plasma Source
setup, which is primarily designed to perform electronegative gas plasma experiments …

In this work, different plasma parameters, such as electron density, temperature, and
negative ion density are measured in both the source and expansion chamber of the …
