Abstract

Correction of an angle of tilt of an ion beam front in a Time of Flight (TOF) mass spectrometer is described. In one aspect, an ion beam front tilt corrector can include an electrode that, when applied with a voltage, defines an equipotential channel of particular dimensions to allow for ions in different transverse positions along a transverse axis of the equipotential channel to have different traversal times.
