ABSTRACT:
The present invention relates to time-of-flight mass spectrometers that use a pulser to provide an orthogonal acceleration to a continuous flow of a beam of ions so as to cause a packet of ions to flow out into an orthogonal direction and enter a detector. The invention makes the size of the emission outflow aperture of a pulser in the direction of the continuous flow of ions greater than the size of the aperture of the ion detector in the direction of the continuous flow of ions. In particular, the size of the ion emission aperture is at least twice as large as the size of the aperture of the detector.
