IRRADIANCE MEASUREMENTS WITH HIGH TIME RESOLUTION

Abstract

Data are presented on the measurements of the distribution of irradiance as a function of time for three detonations. A high-speed bolometer with a 50-micrn sec time resolution of a modified Naval Research Laboratory (NRL) type was employed. The three detonations were all air bursts, with two at 4,800 feet MDL and one at 36,620 feet MSL. Data from other detonations are also presented. The high-speed bolometer used gave direct data for the thermal pulse on the time to the first maximum, time to minimum, time to the second maximum, the ratio of the radiant exposure of the first pulse to that of the second pulse and to the total radiant exposure, and the ratio of the peak irradiances at the time of the two maxima and the minima.
