STERLING EVENT CLOSE-IN PHENOMENOLOGY MEASUREMENTS

摘要

The Sterling Event, the first decoupled nuclear shot in the underground detection program, was executed December 3, 1966, at a site near Hattiesburg, Mississippi. In the region near the cavity, measurements of stress history, cavity pressure, parti¬cle acceleration, and cavity collapse were made for use in defining and evaluating the parameters controlling the magnitude of the decoupling ratio. Data are presented for the accelerometers, one stress-history gage and the cavity-collapse transducer. Al¬though the acceleration and cavity-collapse data are satisfactory, data from several gages were not recorded;these losses were primarily the result of an unusually large ground loop present in the electronics system.
