Highly ionized hollow cathode discharge
WebMar 27, 2012 · Fast neutral atom and molecule beams have been studied, the beams being produced in a vacuum chamber at nitrogen, argon, or helium pressure of 0.1–10 Pa due to charge-exchange collisions of ions accelerated in the sheath between the glow discharge plasma and a negative grid immersed therein. WebJul 25, 2024 · The main characteristic of the hollow cathode discharge compared to conventional electrical discharges is the high ionization rate, which can be a magnitude larger to normal glow discharges. The hollow cathode discharge takes place within the bounding walls of a cathode cavity.
