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 …

Abstract The Magnetized Plasma Interaction Experiment (MAGPIE) is a versatile helicon
source plasma device operating in a magnetic hill configuration designed to support a broad …

The availability of future fusion devices, such as a fusion nuclear science facility or
demonstration fusion power station, greatly depends on long operating lifetimes of plasma …

Proto-MPEX is a linear plasma device being used to study a novel RF source concept for the
planned Material Plasma Exposure eXperiment (MPEX), which will address plasma …

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

A plasma cell prototype for the plasma wakefield accelerator experiment AWAKE based on a
helicon discharge is presented. In the 1 m long prototype module a multiple antenna helicon …

In this paper, we investigate the propagation and damping of helicon waves along the length
(50 cm) of a helicon-produced 20 kW hydrogen plasma (${{n} _ {\text {e}}}\sim $1–2$\times …

Antenna radiation patterns in the vicinity of a helicon antenna are investigated in hydrogen
plasmas produced in the MAGPIE linear plasma device. Using a uniform cold-plasma full …

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 …

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 …
