Converging Annular Time-of-flight Mass Spectrometer

Schematic of CAT

The schematic shows Kore's novel spectrometer geometry (patented) which starts with a ring shaped ion source. The ions are extracted perpendicular to the ring and deflected inwards so that as they proceed through the spectrometer each annular bunch of ions converges to a relatively small size by the time it reaches the detector. This allows a relatively large source to be used with a small detector giving the best of both worlds in terms of sensitivity, mass resolution and cost.
