Abstract
An ion accelerator for a time-of-flight mass spectrometer includes a pulsed ion accelerator positioned proximate to a sample plate and having an electrode that is electrically connected to the sample plate. An accelerator power supply generates an accelerating potential on the ion accelerator electrode that accelerates a pulse of ions generated from the sample positioned on the sample plate. An ion focusing electrode is positioned after the pulsed ion accelerator. A potential applied to the ion focusing electrode focuses the pulse of ions into a substantially parallel beam propagating in an ion flight path. A static ion accelerator is positioned proximate to the ion focusing electrode with an input that receives the pulse of ions focused by the ion focusing electrode. The static ion accelerator accelerating the focused pulse of ions.
