Helicon waves are waves in low-temperature, partially ionized plasmas in a dc magnetic
field (B-field). The study of helicons involves both ion–neutral collisions and Larmor orbits …

Helicon high-density (up to~ 1013 cm− 3) plasma sources using a radio frequency wave in
the presence of a magnetic field under a low pressure are very promising for various …

1999 Litografia Geda, Torino, 1999, p. 107 Mini-RFTF. Experimental observations of the
radial shape of the density profile can be quantitatively reproduced by iteratively converging …

This paper describes a helicon-wave-sustained plasma generated by a novel birdcage
antenna with cosine azimuthal current distribution. The resonant birdcage source maintains …

Helicon plasma sources attract keen interest worldwide. These types of plasma sources can
generate a uniform, high-density (electron density up to 1020 m− 3) and low-temperature …

Radio-frequency (RF) driven helicon plasma sources can produce relatively high-density
plasmas (n> 10 19 m− 3) at relatively moderate powers (< 2 kW) in argon. However, to …

Recent discoveries in a helicon plasma show a decrease in equilibrium plasma density as
magnetic field strength is increased. This can be explained in the framework of a low …

Helicon plasma density may show a non-monotonic dependence on the magnetic field at
low strength, so-called “low-field peak (LFP).” We presented the multiple LFPs and the …

We present time-resolved measurements of an edge-to-core power transition in a light-ion
(deuterium) helicon discharge in the form of infra-red camera imaging of a thin stainless …

The Proto-MPEX helicon source has been operating in a high electron density'helicon-
mode'. Establishing plasma densities and magnetic field strengths under the antenna that …
