A final focus electrode includes a cylindrical base on one end and a conical portion on the other end such that the diameter of the conical portion is greater than that of the base and also gradually increases with distance from the base. The conical portion of the final focus electrode is located inside a cylindrical accelerating electrode such that it is coaxially surrounded by the latter.
