From examination of EKXL code run output and of analytic studies of particle density distributions, a picture emerges of the behavior of ions and electrons in flow through simple Polywelltm systems. This shows that the region within the momentum-limited core is net positively charged, and always develops a virtual anode. If the ion current, for given electron drive current, is allowed to become sufficiently large, this virtual anode increases in height above the potential well minimum and the core radius broadens accordingly.
