Two devices for the measurement of the velocity distribution of ions from laser-produced plasmas are presented. Characteristics of the normal Thomson Parabola apparatus are examined under the constraints of small overall dimensions few centimeters and moderate ion velocities. A second device uses a novel modification of the Thomson Parabola apparatus to produce separation of the ionic species into linear traces. The same constraints are employed for this apparatus. The use of solid state track detectors, charge collectors, and microchannel plates in both devices are discussed.
