The present invention provides charged particle energy deflectors, analyzers, devices, device components and methods for terminating charged particle systems and electrically isolating device components. One embodiment of the present invention provides a transparent field termination system for a cylindrical charged particle deflector that is capable of providing an electric field that closely approximates the substantially logarithmically varying electric field of the deflector. The present invention also provides multichannel charged particle analyzers and multichannel EEL spectrometers capable of measuring charged particle energy distributions, including electron energy distributions, with enhanced resolution and sensitivity compared to conventional analyzers.
