Abstract
A theory of the depth dependence of the first bubble pulse period of an infinitely long cylindrical charge is developed. The charge is represented by a cylinder of adiabatic gas and the time equation for expansion from its initial radius to equilibrium is derived as a function of the weight of explosive per unit length and the hydrostatic head. There is substantial agreement between theory and experiment, the agreement improving as the length-to-diameter ratio of the charge increases.
