ABSTRACT:
The method of measuring at least two distinct properties of a single particle comprising: a) accelerating a particle having a certain velocity in at least one acceleration region, the acceleration region being a region in which the velocity of the particle changes, to cause the velocity of the particle to vary; b) detecting a passage of the particle at each of three or more locations within or near an acceleration region; c) measuring a set of time-of-flight values for the particle, each time-of-flight value being equal to a time interval between the passage of the particle at two locations; and d) determining the values of at least two properties of the particle by comparing the set of time-of-flight values for the particle with calibration data.
