ABSTRACT:
A time of flight spectrometer having a dynode detector in which a set of dynode plates at an output end of the dynode is each connected to an associated capacitor that functions as a charge reservoir for said dynode, thereby substantially avoiding saturating this dynode. A grid is place adjacent to and parallel to a front surface of a target to produce an acceleration region that accelerates ions substantially perpendicularly away from said front surface, thereby reducing time of flight deviations caused by nonperpendicular emission of ions from the target. A biased guide wire aligned perpendicular to the front surface of the target produces an electric field that images ions from the target onto a detector.
