Inductive method of registration of shock-wave parameters in condensed media

We discuss a method of measurement of particle velocity behind a shock-wave front in a condensed dielectric medium. The method is based on recording of the electromotive force (emf) that is induced in a current-carrying coil when the shock wave deforms it. A toroidal probe coil was used to reduce electrical noise. A current of 500 A was supplied to the coil by means of aperiodic discharge of a capacitor. The recorded emf amplitude is proportional to the measured particle velocity and equals 20 V for a velocity of 1 km/sec. The influence of some phenomena accompanying shock-wave propagation along the coil on the accuracy of the particle-velocity measurements was estimated.
