AN ANGULAR ALIGNMENT OF THE ION DETECTOR SURFACE IN TIME-OF-FLIGHT MASS SPECTROMETERS

摘要

Electrostatic deflectors (11, 12) are used in a time-of-flight mass spectrometer to steer ions (41) into a detector (40) positioned at the end of a drift region (28); where the detector (40) is tilted in relation with the steered ion beam (41) in a manner which improves mass spectral resolution.
