Abstract

A method is described for space-focusing ions accelerated to constant momentum that includes accelerating ions in an electric field having a negative gradient in the direction the ions are accelerated. A single stage ion accelerator (400, 410) that provides a decreasing electric field along the ion optical axis also is disclosed. Combined with a detector (414, 418) placed onto a space-focal plane where ions are focused after being accelerated, the accelerator provides a simple, sensitive time-of-flight mass spectrometer (416). In combination with an energy analyzer (410), the disclosed decreasing electric field ion accelerator provides a mass analyzer (416) that can measure constant momentum spectra, and that may be combined with existing mass spectrometers to enable a number of novel mass spectrometric methods.
