An experimental method was developed to measure the pressure-time profile of a liquid in a reverberation or multiple-shock experiment. Profiles, with peak pressures to 30 kbars, were measured for carbon disulfide using shorted quartz gauges (25.4 mm diameter by 3.15 mm thick); these gauges formed the back surfaces of cells which contained the carbon disulfide. Sapphire plates were used both as impactors and as the front surfaces of the cell. Up to six pressure steps were clearly observed in the quartz-gauge output. Measured pressure-time profiles were compared to profiles calculated with available equations of state. The experiments agreed well with profiles predicted with an equation of state proposed by Sheffield [J. Chem. Phys. 79, 1981 (1983)]. Calibration experiments were performed to characterize both the initial current response and the subsequent current ramping of the shorted quartz gauges used in this study.
