摘要： A pulse-type ion source derived from a pulse laser produced plasma provides an ion beam which is analyzed in a time-dependent field which varies monotonically as an inverse function of time for the pulse period. Ions of common charge to mass ratio are collected at different points after executing a trajectory, which, because of the time dependent nature of the field, traverses the same path for ions of the same charge to mass ratio, irrespective of their initial velocity when entering the field; thus, facilitating the determination of the mass, charge and energy spectrums of the entire population of particles emitted in pulses or bursts, simultaneously and even from individual bursts.
