ABSTRACT:
The invention covers novel ion reflectors which are conceived principally for use in time-of-flight mass spectrometry. Caused by special electrodes of conical construction, such ion reflectors also have special ion-optical properties which are made possible through optimum compensation of the spherical and chromatic aberrations both of the ion flight times and of the ion flight paths. The time and place focusing of the ions hereby achieved means for time-of-flight mass spectrometers high mass resolution capability and high transmissions.
