Abstract
A multi-reflecting time-of-flight mass spectrometer comprises a pair of parallel aligned ion mirrors and a set of periodic lenses for confining ion packets along the drift z-direction. To compensate for time-of-flight spherical aberrations T|zz created by the periodic lenses, at least one set of electrodes are disposed within the apparatus, forming an accelerating or reflecting electrostatic fields which are curved in the z-direction in order to form local negative T|zz aberration. The structure may be formed within an accelerator, within flinging fields or intentionally and locally curved fields of ion mirrors, within electrostatic sector interface, or at curved surface of ion to electron converter at the detector.
