Those formed in the center move radially, frequently in a thin blue beam, but tend to hit the wall and stay there if the chamber is metal-walled.

It is possible to bias the outer grid a little positive and emit electrons to it, or create electrons from the glow discharge, in which case the electrons go to the outer grid and oscillate there for a while. This makes the glow discharge process brighten substantially. Magnetic fields greatly enhance this effect.
