Abstract
An apparatus, system, and method are disclosed for modulating electric current. An electron source electrode provides a flow of electrons in a partial vacuum environment. An ionizable gas in the partial vacuum environment forms positively charged ion particles in response to impact with the electrons from the electron source electrode. Application of a bias voltage differential between a first bias electrode and a second bias electrode in the partial vacuum environment forms an electric field gradient in a path of the flow of electrons. A collector electrode in the partial vacuum environment collects more electrons than ion particles when a collector electrode input voltage is above a threshold, and collects more ion particles than electrons when the collector electrode input voltage is below the threshold.
