Abstract
A controlled gradient device acts as a reflectron that controls the velocity and direction of a charged particle stream when an external voltage source is applied. An enclosing insulating structure has a metallized contact ring on each end. The interior surface has a resistive coating to provide a continuous electrically resistive surface that generates a desired voltage gradient along the length when a voltage is applied across the metallized contact rings. Each of the metallized contact rings can be a metal mesh that is coincident with a cross-sectional region of the conduit so that the electrical potential is constant at these locations.
