Multiturn spiral time-of-flight mass analyzer based on cylindrical sector fields and periodic lenses

Based on numerical simulation investigated is a possibility to use in multiturn sector time-of-flight mass analyzers with spiral ion motion of an array of periodic lenses, similar to used in mirror multireflecting time-of-flight analyzers. It is shown that this solution retains the resolving power of the mass analysis while considerably simplifying the design of the device because of using cylindrical sector fields and adding a possibility to double ion flight path length with the aid of reflecting ions in the direction of the spiral drift.
