An experimental technique is discussed for measuring the mass‐velocity distribution of material ejected from strongly shocked surfaces. The two major advantages of this technique are, first, that it is useful for measuring large amounts of surface ejecta and, second, that it allows a direct determination of the mass‐velocity distribution of ejecta, without the need for differentiating experimental data. The method has been applied to a measurement of surface ejecta from shock‐loaded porous tungsten.
