Abstract

A conventional VMI (velocity map imaging)-TOF (time-of-flight) spectrometer is modified by adding an extra electrode. By this small modification, the longitudinal focus can be realized for TOF mass resolution while maintaining the lateral focus for optimal VMI energy resolution simultaneously. The mass-resolving power by four-electrode ion optics is greatly enhanced. Our design is especially useful in experiment with a non-focused laser beam.
