摘要：

We present the development of an explosively driven physics tool to generate two mostly uniaxial shockwaves. The tool is being used to extend single shockwave ejecta models to account for a second shockwave a few microseconds later. We explore techniques to vary the amplitude of both the first and second shockwaves, and we apply the tool experimentally at the Los Alamos National Laboratory Proton Radiography (pRad)facility. The tools have been applied to Sn with perturbations of wavelength lambda = 550 mu m, and various amplitudes that give wavenumber amplitude products of kh is an element of {3/4, 1/2, 1/4, 1/8}, where h is the perturbation amplitude, and k = 2 pi/lambda is the wavenumber. The pRad data suggest the development of a second shock ejecta model based on unstable Richtmyer-Meshkov physics.
