Induced shock propagation on the Non-Proliferation Experiment

The Explosive Effects Physics Project at the Los Alamos National Laboratory planned and conducted experiments on the NPE (Non-Proliferation Experiment) as part of its effort to define source functions for seismic waves. Beyond the explosive chamber, the detonation induced shock propagated through the saturated tuff of the N-tunnel complex. The CORRTEX (COntinuous Reflectometry for Radius vsw Time EXperiment) system was used to investigate the shock propagation in two drill holes and the access drift. The CORRTEX experiments fielded will be described. The data obtained are reviewed and an apparent asymmetry in the radiating shock is discussed
