Wedge-Shaped Reflector of Ions and Ion-Optical Features

The prospects for creation of the new type of laser time of flight mass spectrometer were described. The mass spectrometer is based on usage of a reflecting wedge-shaped mirror as an analyzer of the ions by masses. The analyzer provides time focusing ion by both energy and initial angle divergence of ions from the source. Time focusing is carried out for the ±20% energy range, what is at least 2 times more, than for known ion-optical systems for similar usage. The resolution of the mass analyzer is ∼850 for extremely small overall dimensions (∼10×10×5 cm).
