Abstract
A technique employing volume conductive electrodes for the generation of linear or non-linear electric fields is provided for devices used in charged ion optics. A hollow cylinder of a conductive polymer, which is loaded with conductive carbon particles or inherently conductive, and which is used to improve the performance of a dual stage gridless reflectron. Instrumental resolution measurements comparing a conventional discrete ring reflectron with a hybrid polymeric/discrete ring validate the design.
