ABSTRACT:
An extraction electrode manipulator system, comprising an ion source, a suppression electrode and a ground electrode, wherein the two electrode are supported by coaxially arranged two water cooled support tubes. A high voltage insulator ring is located on the other end of the coaxial support tube system to act as a mechanical support of the inner tube and also as a high voltage vacuum feedthrough to prevent sputtering and coating of the insulating surface.
