A time-of-flight analyzer with the path length 2.2 m has been constructed and tested by employing a pulsed ion gun. The optimum time resolution achieved in this analyzer was t/Δt = 6500. The time-of-flight apparatus was used for velocity analysis of fast Li atoms produced by charge exchange reactions in moderate energy Li+-Li collisions. The pulsed alkali-ion beams with time duration of a few ns have been formed by chopping the well-collimated continuous beams. For the pulsing a negative square-wave voltage was applied to a pair of condenser plates.
