WITHDRAWN Gopher 2022: Close-in Signatures From Shallow Explosions in Unconsolidated Environments
Description:
WITHDRAWN Our team at Los Alamos National Laboratory conducted two field-scale chemical high-explosive (HE) experiments in September 2022 nicknamed Gopher S and U (for Surface and Underground) to improve capability for rapidly conducting shallowly buried HE experiments and to provide novel close-in measurements of explosion phenomena from this emplacement scenario. Downhole diagnostics in the main borehole and satellite borehole included pressure transducers, thermocouples and downhole sampling for a suite of fission relevant gas tracers. Surface diagnostics included a 3-component accelerometer within the ejecta crater, high-speed video of the evolving surface disturbance, and a DAS cable deployed on the surface stretching from 5 to 100 meters in distance. A local permanent seismoacoustic network at LANL used for seismic hazards also recorded the explosions out to several kilometers. Downhole diagnostics (that were not damaged or ejected) recorded the explosive cavity formation and contraction as well as the tracer gas injection and migration. Post-shot recovery of the experiment canister provided additional information on the early-time behavior of the energy and material deposition in the sub-surface. Results from these experiments help to understand and predict the complex interaction of engineering and geology that define the explosive phenomena from shallowly buried explosions.
