We have used Lawrence Livermore National Laboratory's (LLNL's) linear, and new coaxial, electric guns in a variety of studies involving 1-D shock waves produced by the impact of plastic flyers at velocities up to 18 km/s. Flyer integrity and characteristics of the pressure pulse at impact are compared with code predictions for a variety of flyer thicknesses and velocities. Applications discussed include a study of the net forward impulse gain measured for 0.30-mm-thick flyers at normal incidence on thick targets of 6061-T6 aluminum at atmospheric pressure and under vacuum. Use of the LLNL electric gun for equation-of-state studies is described in an accompanying paper. 2 refs., 5 figs.
