Abstract

Systems and methods are provided for time-of-flight analysis of a continuous beam of ions by a detector array. A sample is ionized using an ion source to produce a continuous beam of ions. An electric field is applied to the continuous beam of ions using an accelerator to produce an accelerated beam of ions. A rotating magnetic and/or electric field is applied to the accelerated beam to separate ions with different mass-to-charge ratios over an area of a two-dimensional detector using a deflector located between the accelerator and the two-dimensional detector. An arrival time and a two-dimensional arrival position of each ion of the accelerated beam are recorded using the two-dimensional detector. Alternatively, an electric field that is periodic with time is applied in order to sweep the accelerated beam over a periodically repeating path on the two-dimensional rectangular detector.
