Abstract
A multi-pass time-of-flight mass spectrometer is disclosed having an elongated orthogonal accelerator (). The orthogonal accelerator () has electrodes () that are transparent to the ions so that ions that are reflected or turned back towards it are able to pass through the orthogonal accelerator (). The electrodes () of the orthogonal accelerator () may be pulsed from ground potential in order to avoid the reflected or turned ion packets being defocused. The spectrometer has a high duty cycle and/or space charge capacity of pulsed conversion.
