A novel type of ion spectrometer for laser‐produced plasma diagnostics is described. The Thomson parabola configuration is used to separate the expanding plasma ions according to their different charge‐to‐mass ratios. One particular ion species is subsequently collected by a parabola‐shaped charge collector. In this way ion velocity distributions of a single charge‐to‐mass ratio are obtained through simple time‐of‐flight analysis. Measured ion energies can be as low as 1 keV per nucleon.
