Analysis
This paper investigates the generation and confinement of a plasma column using a hollow cathode discharge in a linear plasma device, focusing on the role of an axisymmetric magnetic field. The study highlights the importance of energetic electron confinement and collisional damping in plasma propagation. The use of experimental diagnostics and fluid simulations strengthens the findings, providing valuable insights into plasma behavior in magnetically guided systems. The work contributes to understanding plasma physics and could have implications for plasma-based applications.
