It is almost impossible to get rid of electrons. Electrons are a glue to make matter, if not the electrostatic forces makes impossible to confine ions but in vary small density.
It is similar to tokamaks but works in a different manner because tokamaks needs a lot of energy, are very difficult to manage and have a lot less particle density. The system is a mix of a cyclotron, a tokamak, a sychroton a pulsotron other accelerator systems and even a tokamak, so we could simplify saying that is a very evolutinated tokamak system.
